Three clear laps at Sebring

Some of you may have noticed I just posted videos from Sebring a couple of weeks ago. But, the video I taped that I was most happy with was too big for streetfire.net. Now I am able to share these laps during the second novice session of the day with the help of Kolia, a premier member of this sight...THANK YOU VERY MUCH. My video was edited at the beginning, given a cover title, compressed a bit to be more managable, and put into wide screen.

Now my idea of a perfect racetrack was an empty one as this was only my second outing, so you won't see alot of cars on track in these 10 minutes of video. I wave by a 911 at the beginning, then later catch a Z3, older M3, and a couple of S2000's. This session, which was about 35 minutes, was good enough to win much praise from my instructor and give me high enough scores that I could probably request a solo test at my next day at Sebring with Chinmotorsports. They were nice words to hear. But, my two instructors so far have made my introduction into tracking very fun and informative...so I am not in a big rush just yet to have to start driving alone.

Being new I have been pretty easy on the brakes so my Hawk HPS pads did fine. I got a bit squirly coming out of the Buttonhole(the tightest righthander) which is a second gear corner, and turn 14(the right hander corner starting the esses just before turn 16 takes you on the back straight) near the end of the day. Those got me some good car control grades since I controlled and recovered from my tailhappy antics. Coming out of the Buttonhole it was due to power-on oversteer. In turn 14 it was a bit of power-off oversteer. These were two seperate laps...and not on the video...and got the comment "well that was fun" from my instructor. By the end of the day at the beginning of every session Bart would say, "ok, put my to sleep" since he hardly having to correct/coach me I did a funny vibration in the last session of the day which was a vibration on hard righthand corners. Not wanting to be an example on some "not what to do" video I came into the pits. Was I getting a flat, something in the suspension, a wheel bearing....nope! It was just some glopped on rubber I had picked up from the race track. What a trip scraping hot mushy rubber off my Michelins and washing rubber worms from inside my rims the next day in my driveway! Any seasoned person I am sure would have known it was no big deal, but for a nuub on the racetrack with his nice and cherished G35 he wanted to drive home...I was a bit freaked until I pitted the car.

So here are the videos.
First: It is three laps on an almost empty Sebring track.

Second: Six minutes with my camera pointed to me...so you can see my ugly mug, the seat move around, and hear me say " I wish my friend with the Cobra could have seen that" when I passed another novice in a super charge Cobra. Oh, and you can see the bonus headroom you can have with no sunroof.

this was from my first day at Sebring with NASA

NASA membership: $40.00
1-Day entry fee to Historic Sebring Raceway: $285.00
Extra Maintenance Costs: $80.00 and counting
The chance to ride in a 911 racecar: Apparently $285.00 and some good luck.
Getting to drive my own G35 coupe around Sebring with an experienced racer coaching me: Apparently $285.00… But I thought the experience was priceless.

Around 4:00 AM the alarm clock rings to start one of the most exciting days of my automotive life…I was too cheap to pay for an overnight stay near the racetrack. My wonderful wife, full of fear of me being injured or killed, makes me some coffee and makes me a care package for the day. She just lost both of her parents in the last year and half, so letting me go was not easy for her. I leave with a kiss and a wave goodbye. After driving in the dark for almost 2 hours the first hint of light begins to show as I pull up to the gates of heaven ..uh.. Sebring Raceway. I arrive a few minutes early and am one of the first cars. That means I get to use/park in one of the track’s pit garages

I unload my goodies for the day, food, water, tools, brake pads, helmet, oil, brake fluid. Luckily I did not need any of the automotive supplies I brought. I checked all the fluid levels, tire pressure, say a little prayer. Put on my magnetic numbers I made with the help of my wife getting the supplies…take a picture. Am I really at Sebring with my own pit! I met some nice people, went through tech, attended my class, and then joined the line of cars on pit lane to meet our instructors.

Walt comes up, I introduce myself, we talk about my car, his past experience, and my experience and expectations for the day. I told him that I play a lot of simulation games… he was unimpressed. I told him I was comfortable pushing my car a bit around the local interstate ramps…he was unimpressed. I told him I could heel and toe and my goals were to have fun and not injure myself or the car. Walt said we would get along fine. So we get in the car and appreciate the extra headroom from not having a sunroof. We have plenty of room even with our helmets on. He drives for two laps, we switch and I proceed to drive like I must have had my eyes closed while Walt was trying to show me the line. But at 3.7 miles and 17 turns, it is a bit hard to remember the line in only two laps. After the 35 minute session that seemed like 10 minutes, we park the car. Walt asks me if I would like to ride with him during his session in his 911 racecar to see where the smoothest line is… HELL YEAH! That ride time really gave me a huge head start over my fellow drivers that had no experience like me. During my second and third sessions, I was certainly not the fastest driver, of course, but I did “pass” a Mustang Cobra, and two Corvettes… one of which was a Z06. During the last session when I caught the Z06 again, Walt said “You know the driver of that Z06 must be pissed he getting passed by an Infiniti G35.” Hehehe. About 15 minutes later in the session the driver of the Z06 caught back up and passed me. He had finally started to really learn the correct line. His instructor did not give him a 35 minute ride in his race car

I made a couple major mistakes, at least in my opinion. I just about dropped a wheel off the track just before the start of a rumble strip. Walt told me if I was any farther over there was a bit of a hole/dip before the start of the rumble strip that could have caused some damage if I hit it. Turn 17 was also the hardest for me to learn. So after passing an inexperienced driver in the Cobra, and keeping up with a somewhat experienced guy in I think a Porsche 926, Walt says “ok, we only need to get turn 17 right” as I’m going through turn 16. I then proceed to attempt 17 way too fast, forgetting that the 180 degree turn tightens up half way through. I let off the gas, the front end plows a bit, then I felt some quick hits on the brakes as the VDC helps the car rotate in the direction the front wheels are pointing. Yes, I left the VDC on and it interfered very little. At the Button Hole it came on fairly often and was annoying, but I realized I was trying to get on the gas too soon. Once my line was smooth, the VDC almost never came on, and I was very happy for the help in turn 17. This was the last time I really screwed up turn 17. During the third session Walt told me I finally figured out the turn and I was fairly consistent.

The concentration required is unbelievable, even at my noobie pace. You are directing and controlling your car at high speeds, looking in you mirrors for people catching you to let them pass, trying to look at the corner workers to make sure no flags are being waved, looking ahead, hearing and feeling for any signs you car is starting to go away…like the brakes and tires. I was being as easy as I could on the brakes and did not rev the engine above 5500. I usually had the revs no higher than 5000. I didn’t want to break the car, especially at a track event. I can’t wait until I can go again

I was so busy looking at where I was going, I couldn’t even tell you my speeds in the corners…just the gear and an approximation of rpm’s. I can say there are four places you can easily exceed 100mph. So turn 1 your in fourth gear, apex near the wall and floor it at apex drift out and hold fourth gear through turn two & reach about 5500rpm. Brake, keep to the right, shift in to third and don’t turn in too early. Left into 3, right into 4, stay to the right and if you don’t turn in too early to the left going into 5 you can floor it before you even reach the apex. I shift through fourth gear, fifth around turn 7 at full throttle, but shifting around 5000. This is where I am catching some inexperienced people in faster cars, because my instructor had me going through the previous esses so smoothly. Trying to be easy on the brakes, I start to slow before the bridge, fourth, third, and should be second gear but I’m getting on the gas too early in the buttonhole hairpin and upsetting the VDC so I stayed in third. You are then full throttle through turns 8 & 9 reaching about 100 again. Slow for turn 10, fifth, fourth, then get into third gear, don’t apex early and ease on the gas at the apex… drift to the left. Its gas on, shift into fourth gear through the left hand turn 11, touch the rumble strip on right at 12. I then straighten the car, brake, third gear as you let the car drift to the left side of the track. If you once again don’t turn in too early, you can get on the gas at the apex of the right hand turn of 13. Full throttle, fourth gear, fifth gear and ease off the gas just a bit and fly through the left turn of 14 and remember to let the car drift out to the right after 14’s first apex because there is another left apex coming…because if you can’t turn for the second apex there is a wall waiting to greet you. You need to stay on the left side of the track after the second apex, straighten up and brake for turn 15, shift into fourth gear. Another set of esses which I love…right, left and continue to drift out to the left wide. If you do this right, you can get a pretty straight shot at the right hand turn 16, get on the gas before the apex, let the right side tires get on the rumble strip and out to the left as you enter the longest straight at Sebring. You will go through fifth gear and get into sixth if you are short shifting like I am to be as easy on the car as possible. I brake, fifth gear, then fourth and finally learn to take turn 17 kind of like a three apex turn. Fastest at the first apex, and continue to SLOW DOWN with a tiny hint of trail braking. If you succeed at this, at least to some degree in my case, you can start getting on the gas just after you pass the second apex. I was not getting much of a launch out of 17 since I kept the car in fourth gear, though I should have been in third. But I took so long to learn a smooth and quick line through the long right hander I didn’t want to change anything. You then accelerate out of 17, get into fifth gear, move to the right side of the track, brake, shift into fourth…start all over again

I leave the track about 5:30PM and try to drive like a normal law abiding person on the 2 hour drive home playing in my mind over and over the wonderful day I had with my Infiniti G35 coupe

Thanks.

The pads were fine, for the way I was braking which was early and moderate. If I were threshold braking everycorner I would have been experiencing brake fade definitely. I did not realize how easy I was being on the brembos until my instructor took me out in his sedan with stock pads and brakes. The fear of running out of track had me being WAY to easy at first.

Just to clarify for any members who did not see my write up from last year. The videos are from my second track day which was with Chin Motorsports and the second post story was with my first experience which was with NASA.

I have not been on the board for quite a while, but at least my membership is up to date. The mini-meet looked like fun in the Tampa/St. Pete area. I can't believe it was just yesterday and I just saw the thread. Well at any rate, I was representing us at Sebring again for the third time. Had a great time once again, car was very reliable, and I qualified to drive solo in the afternoon. The video is long, 25 minutes, but there is alot more traffic in the video than my last one. At the end of the day, after my 45 minute solo session you could actually hear the hot Michelins sticking to the pavement while driving down pit lane.

Nice to hear from you again... It looks like you had a great time at Sebring this year.

Good videos too. You dusted off a few of those guys, too. I didn't think you were supposed to pass other cars, but that certainly isn't the case. I could hear you and the guy in your car talking, but I couldn't really tell what you were saying.

Cool vids...

Nice! I commend you on being one of a handful G35 drivers on here whose interests go beyond the drag strip or putting 20" wheels on their car. I just did my first DE at Moroso last weekend and all I can say is, this is more addicting than crack

Thanks for the great writeups, I'm sure I'll find them useful as I study Sebring. I wanted to have at least one event at a smaller track under my belt before I head up to Sebring, but I'm definitely going on December 30th with Chin. Are you planning on signing up?

A couple of things I'd be interested to know...

How do you do your downshifting? Do you heel and toe? Or do you brake first, and then downshift while still holding the brake but without rev-matching (what my instructor was doing)?

Oh and how does the tech inspection work? Do you have to take your car to an authorized shop and have them fill out an inspection form, then bring it with you to the track, or do they only inspect the cars at the track? How long are the sessions in an open track format?

I actually just spoke to someone who attended the same event, a guy with a black '06 M3 who was there with 2 other guys with a black M6 and silver M3.. you might have passed them somewhere along the way

Trust me when I say that I am definitely not passing the majority of the people there. It is really not about passing at all or comparing your times with others by looking at videos. That being said, it does feel good when you catch somebody when they are in what you percieve to be a faster car...then shortly after an instructor blows your doors off in a spec-race Miata.

I have only been able to afford to go about every six months and we might be out of town between Christmas and New Years. I teach and that is my two week break...so plenty of time to travel. We will see.

I do heel-toe, but would recommend learning on the street at slow speeds. If you know how to heel-toe it is actually easier at the higher speeds you see at the track, but you don't want to screw it up at the track and spin yourself into the grass or a wall. I have only used street pads to date. Just make sure that your brake fluid is new. I also start my tires at about 38 psi when cold...they will be in the 42-45psi range after a session. You can only pass with a point-by on the straights from the car you have catched. This is why I never passed the novice in the BMW Z-8 that I was following at the end of the day. Also the second you start looking at your speedometer, worring about catching somebody or keeping ahead of somebody you shouldn't be you will probably make a bad mistake. You are only out there for fun and to come home in one piece. Sebring is the only track I have ever been by the way. If you sign the inspection form that it was inspected, they pretty much take your word for it. If things are not in order, it will be you and your car paying the price. I would have the car looked over.

Gotto go for now. I will read this later and make sure I answered all your questions.

Yes. It is very expensive crack

Haha, that's so true, it seems like a lot of novices think it's all about speed and passing everyone, when in fact you have to be slow to learn and perfect the line. Getting faster comes naturally after that. I put my car in 3rd and did a couple of laps just to concentrate on the line and not worry about shifting.

Thanks for the advice and I hope to see you out there!

A new track day...April 14

Well again I had an absolute blast at Sebring with Chin Motorsports. This was my first solo day and I must admit it was the most fun I have had yet. I brought along a friend who was a student of mine from five years ago. He has since graduated college. I also ran into a former instructor of mine...Bart...who was a joy to work with all day. He is very patient, informative and just interesting in general to talk to. Anybody would be lucky to have him as instructor, especially when they first start doing track days.

I still run my car totally stock or at least with "street" equipment. I have Hawk HPS pads and Michelin Pilot Sport 2 tires. I believe from watching my videos that my best lap of the day must be about 2 min 55 seconds. Of course I say this now that I am home in one piece like I cared during my track day. I am of course happy that I once again came home in one piece.

The "good, the bad and the ugly" would be within my first few hot laps of the day. I went VERY wide in turn seventeen coming way closer to the tire wall under the bridge than I ever want to be again and then missed turn 13 braking straight into the run off area within the same lap. So I turned around, drove into the pits and said hello to the lead instructor. I explained my error, what I did, and he checked over the car. I then took a couple of cool down laps in the paddock area and took a deep breath. I then analyzed what I had done wrong which mainly was not completing all my braking in a straight line and losing braking force on the inside front tire as the weight of the car shifted while I was trying to finish my braking. The rest of the day was very good in my book with only minor errors or misjudgments...you know no lap is perfect. I also tried very hard not to rev my engine over 5500 rpm even though the red-line is 6500 again trying to ensure that I drive my baby home in one piece. Other Nissan drivers have told me that this is not necessary but I feel better about my short shifting. I also used fourth gear coming out of turn 17 even though I could probably have gone down into 3 only because it simplifies the turn for me saving a downshift and I am not racing. Good thing or I would be losing

My friend got to ride with me for much of the day after I got into my rhythm of course. My former instructor also gave him a ride. He also took some great pictures. A small sample follows. The video is long about 35 minutes and I have not watched the Streetfire video since I obviously have a non-compressed version on my own computer. If there is a problem with it let me know...not that I could do too much to fix it. Hope someone enjoys the video and the few pics.
