Please gimme some details and numbers..
and please rate the tires you guys are using for autoXing and tracking..

thanks...hope i can get an idea of what u guys use of ur Gs...or Zs..

 

BBS RGR 18" Diamond Black 8.5 F, 9.5 R. Dunlop SP Super Sport Race 245/35-18 F, 265/35-18 R. These are the combo I use for summer driving and (road race) track day use.

The BBS are almost as light as the 18" Rays forged alloys that came with my car and look awesome to boot! As for the tires, they take a lap to come in, but are quite sticky after that. There are better R-compound tires out there (Kumho V710, Hoosier R3S05 or Michelin Pilot Sport Cups), but they are 2-3X as expensive as the Dunlops. Admittedly, the Super Sport Race are a discontinued model, but remain a bargain for fun track use. Another point in their favor is they have a 'gatorback' tread pattern with enough depth (6/32nds unshaved) that driving in the rain is not that big an issue.

 

Hey thanks alot, thats a very indepth reply
Do u need spacer for that set up?

Is your set up pretty common in G trackers?

thanks alot..!

 

What autox class do you plan on running in?

 

No spacers required for these particular BBS for my 350Z. Whatever wheel you get, I don't recommend using spacers if you can help it. There are additional loads put on the wheel bearings of either the Z or G when you use them. Get the right offset and spacers are redundent.

I've never seen another Z (or G for that matter) using BBS RGRs with the Dunlop SS Race tires at any track event.

 

Hey thanks for the reply, does it make a big difference if i go with 8.5 front 9.5 rear and 9front and 10rear?

thanks

 

If you get hub-centric spacers, they reduce the load on the lugs and bearings, since the wheel sits directly on the spacer much like stock.

 

Hub-centric spacers help, but using spacers remains a stopgap measure. The scrub radius of the front suspension will be changed with spacers and if you're going to the track, compromises are not a desirable quality.

I think unless you have the HP and TQ to support 9.0 F and 10.0 R wheels, it's overkill. There's such a thing as having TOO much rubber on the road. Rolling resistance becomes a bigger tradeoff to cornering power.

 

So will 8 by 9 be more suitable in my situation?

I am not planning to FI my car so lack of HP and TQ is an issue...

what tires should i use? and size....

you do not want to stagger that much. the car will handle more neutral with matched tires. i suggest a minimum of 245 width front, and 245 width rear. although i would probably go with a 265 rear, and a 255 front.

i don't think you need more then 265mm on the rear, esp with sticky tires, a better lsd, and/or good driving. the wider you go on the front end, the better all that weight will get supported in a corner. some people say you will lose delicacy to the steering, but i never noticed such.

i am guessing you are looking at 17 and 18 inch wheels. the most important thing is the diameter, offset, and width. make sure there are tires for the widths you choose. also make sure it will clear your brakes, or any bbk you plan on getting.

some good wheels... enkei's racing series... rpf1, rpf1rc, nt03+m, etc... 5zigen... fn01r-c (or r) mainly, volk 1-piece wheels

if your car is ivory pearl, i suggest a nice 18 inch rpf1 or rpf1rc in silver. very classy and simple, no flash, perfect for the track... keeps the attention low on the street.

 

also, there are many many tire choices that are out there. good non-r compound tires:

bfg gforce kd
bridgestone potenza
pirelli p zero (all varieties, esp corsa)
kumho mx
toyo t1r
michelin pilot sport
bridgestone s03
yoko neova ad07

and the list goes on and on

good r-compounds... toyo ra-1, kumho v700, v710, nitto nt01, avon tech r, michelin pilot sport cup, advan a048, a032... and the list goes on

you have to try tires, and see what you like, there is no magic formula... go with something tested and proven. tire choices for races and auto-x are published online. gradually go to stickier and stickier tires as your skill builds.

i don't suggest an r-compound if you street drive the car (unless you get track wheels). you will not get traction in the wet, or when the tires are cold.

 

Wheels: A-Tech Finalspeed in gunmetal 17x9 +27 all around

Tires: Avon Tech-R 275/40/17 R-Compounds all around

No spacers, and they clear Brembos w/plenty of room to spare.

PICS on my cardomain

 

use your stock wheels and tires and just make sure the tires are in good shape.

I ran the car in stock form last year and it performed fine, but I had only 5k or some miles on the tires then and now it's got over 10k so this might be the last season for them.
