What wheels are people running for AutoX?
 

So after searching and reading various threads and it seems that the preference is to run a squared setup for AutoX?! Just wondering what the Nismo guys are running for their wheels and tire sizes. I know I keep seeing that 295's will fit all around but I'd rather hear that someone is actually running that size instead of just a "it should work" comment. I'm running ASP so I'm not restricted to the factory wheel size.

Also I'd really like to avoid using spacers if possible since I do drive my Nismo on the street also and will be switching between my Nismo wheels and AutoX wheels frequently.

Thanks in advance for the help.

I run Forgestar 10" front, 11" rear 18" diameter. Many more race tire options in the 18's. I run 315's.

Can I assume the F14's? Also what are the offsets on those wheels and do you have to run spacers?

Yes F14's. 18x10 ET+37, 18x11 ET+28.

I ended up needing a 5mm spacer up front to prevent the tire rubbing the control arm under corner load so you could bump the front offset up a touch to negate the need for the spacer, the rears fit perfectly.
A little bit of extra front camber may be required to make it all fit nice. I use -3.0 but -1.5 to -2.0 is probably sufficient.

What square tie setup do you recommend for a nismo on Re11s and dropped on swifts? I was thinking of doing 285/35/19 all around cause Mike recommended it. Do you think I can get away with more without much rub during heavy conering?

You can fit up to a 315 up front with no rub if you have the right wheels with the perfect offset. The ideal offset varies depending on how much camber you have.

On the stock Nismo wheels 285 or 295 all around would work pretty well I think.

I will be trying to stay in spec camber wise for the most part. I will be ordering spl arms for the rear to go with my swifts springs. From what i have read this should keep me in spec, and the front doesnt seem to need them. Thank you much Chris.

You'll probably gain about -0.5 degrees or a little more up front from the swifts which will be good and help tuck the fatter tires. You won't need camber arms unless you were trying to get extra camber up front.

I was pretty sure I would need the camber arms for the rear. Thats what I get from reading in the official swifts springs thread.

Camber gain in the rear will be much greater. Without camber arms in the rear you would be looking at -2.0 as the minimum.

ouch. Thanks for your knowledge. Do you think I should mess with any type of spacers on a square set up of 285/35?

I would avoid the spacers if possible. Are you getting wheels with square offsets or staggered offset?

Im new to all this, so Im not sure what you mean? I am putting the tires on the stock Nismo 19s.

Is this what you are looking for?

370Z NISMO Wheels and Yokohama ADVAN tires.
Lightweight forged aluminum-alloy 19" x 9.5" +40mm offset (front); 19" x 10.5" +23mm offset (rear) Weight: 20.5 lbs. (9.3kg) – front; 20.9 (9.5kg) – rear

Okay that will be fine then. Wheel offset can be used as a tuning tool to alter the 'track' (width between wheels) and hence alter grip. Wider track from lower offset means more grip. With the stock wheels you have a little wider rear track which will keep things in check, if at some point you decide to go with a set of dedicated track wheels that have even offsets all around then you can decide on spacers.

Got ya. So for now spacers are more for show it in my case it seems.

I autocross. Everyone recommended Dunlop Direzza Star Specs for 18" wheels, but they don't make it for 19". Other tire I was told to get is the Hankook Ventus R-S3 (the big daddy of street summer tires by Hankook. Stay away from V10s) - which comes in staggered OEM sizes. (staggered means different tire size in front than in back).

I am ordering some today from Alex at Tirerack and should be here in a few days!

Hankook*Ventus R-S3


These tires are going to stick like glue after break-in and I don't need to modify any spacers or roll fenders or anything. Staying in stock. (Road Tire RWD class... graduating myself out of novice next time)

very nice!

Not sure you run 18 on rtr legally unless you have a base with no sports package. Not that locally anyone will care.

For ASP I think the dope setup would be 18x12 rear with 335 and 18x10.5 front with 315. Anyone running that yet?

What offset and camber setting would you be running to fit that much wheel and tire in the front? :icon14:

I've only run 345 on an 11". I think a 12" wheel would work too, but be advised that the 345 takes all the space and then some :) It rubs on the inside just a hair under lateral load. I'm not sure what the exterior "flushness" requirements are for SCCA, but it is possible that I could move the wheel out another 5mm without rubbing the fender.

I use a 10" wheel right now with a 315. The offset will need to be quite conservative, +27 to +32 with 3 to 3.5 degrees of camber. With more camber you would need a lower offset. I'm going to test fit my 10.5 +15 up front but I think that might be too much.

This stuff is way above my head. :-(

I have run Sport Package Rays and 265f/285r RE-11s in auto-x once and the car is very progressive at the limit with little to no understeer, but low speed corners need a bit of throttle to overcome the slower turn in. Grip is increased dramatically over the last time I ran auto-x with the stock RE050s.

In the ASP class there is no "flushness" requirement. Wheels of any diameter, width, and offset are permitted.
