Yep, that looks about right.
 I corner ballance/ set-up cars all the time. I have done alot of Z's and G's. your car came out pretty good (well ballanced), for not having coilovers. You should have scaled the car with you in it though.

Yeah. I was feeling kind of rushed and realized that I should have weighed the car with me in it just as we rolled it off the scales. Doh! I'm about 140 lbs--135 lbs on a typical autox day as it's too easy to get dehydrated here in Texas right now. Assuming a weight of 140 lbs, a track of 60.6", a wheelbase of 112.2" and my butt 12" in and 60" from the front axle the calculated weights should be (with some roundoff error):
weight: 3536 LF 980 RF 963 LR 815 RR 778 Quote:

wa2good, have you ever weighed a G without a moonroof? I'm curious as to how much weight this option adds.

No, I haven't. I would be curious as to what this option weighs as well.

"Passenger seat all the way back on rails" --- What a great idea!! Move the weight a lil more to the rear eh
 I need to start doing this at track days/auto-X's.Do you bother talking out the stock jack/tools as well?

Yeah. I empty the trunk more so I can fit my race stuff in rather than to lighten the car. It seems to handle better with more weight over the rear--for autox at least. That's why I run a full tank. I have an adj front sway bar and konis on order. I may do some testing with lightening the rear to see if I can compensate for shifting the weight forward with the new adjustments.

Thanks for the info! Great insight
I hope that guy with "3 year G-Driver expertise" get's a hold of this information. Him and his bogus claims  Hey Scott, do you know of any place near Los Angeles where I can weigh my coupe? How much does it usually run for (price)? .

very interesting info. Looks like the infiniti was dead on with 03-04 coupe weight. It was listed upper 34xx lb. Im guessing they listed the weight with full tank of gas and the tools inside. The 03-04 sedans are listed in upper 33xx lb. Looks like I will be looking for a place to weigh my car.

I see most 03-04 Coupe's listed in the lower 3400's according to mags & Infiniti. I agree that Infiniti probably weighed the car with a full tank of gas & tools; if balaguru would have weighed his car with the tools/spare (already including the full tank of gas he had), it would have probably added another 30-35 lbs which would put him exactly where most 04 Coupe's are rated (~3430 lbs) Good to know that Infiniti's weight claims are legit; I just never knew they weighed it with a full tank (including tools/spare). .

I had mine corner weighted and came up with very similar numbers. I was at 3390 lbs.
- 03 Coupe 6mt - No nav, no aero, moonroof, premium package - 350Z 18" 6 spoke wheels with 245 R-comps - Everything stock - Removed spare but with jack - 1/3 tank of gas I bet your Hoosiers/Enkeis were alot lighter than my wheel/tire combo since I had a lot less gas in my car. Wouldn't be that tough to get down to 3300 flat range with a lightweight exhaust, a lighter battery, and less gas.

I can do it down here in San Diego if you need me to, or Steve at M-Works is in the LA area and he can corner ballance your G as well. Price should be between $300-$500, depending on how off your car is and how long it will take. lemme know if you need any more help.

Yeah, the hoosiers weigh 23 lbs and the enkeis 19 lbs. Do you have a rear spoiler? I know you said no aero, but I thought the spoiler was avabilable without the rest of the aero stuff.
If I run only 5 gals of fuel and pull the muffler assembly I should be able to get the car down to 3275. I just don't know how this will upset the handling and compromise my ability to the put the power down on turn exit. A lightweight battery would be great since it's weight off the front end but is illegal for the stock class. I'll be running the hollow Hotchkis front sway bar which I imagine is lighter than stock so that's a few negligible lbs off the front of the car. I was talking to an LS1 f-body driver at the event who got his car down to 3290-ish with stock legal lightening, so whatever I do I'm not going to be all that much lighter than many of my competitors. However, I don't know how much the shelby gt's weigh. They seem to be the car to have this year in f stock. Quote:

From my weight redux thread.
Quote:
I've taken out 96.6lbs out of the car. A third of that comes from the Spare tire a few pounds from the jack, tools, emergency kit, carpets. The remainder from more extreme (i.e. non-stock) measures. So I'd estimate a stock 07 coupe @ 3500 pounds with a half tank. -G __________________

Is anyone here familiar with the DEKA line of batteries, allegedly (as per the forum linked below) the braille lightweight batteries are essentially rebadged dekas, which is really nice becouse they are about half the price.
