The Official 370Z Autocross Thread

[AutoX Z]

Ran the second divisional event in Dallas last weekend. The car was crazy loose the whole time and no matter what we did in terms of tire pressures, spraying, driving style, did any good. All around very frustrating and very very slow. Got back to Houston and took the tires of the car and discovered this:


Also found this laying around....

Also found this laying around....

For those of you in the New England area there is an un-paxed event this Sunday run by Track Club USA. See here for info.

Getting this thread back up top.

The shocks are still not completely on the car. It has been a nightmare trying to make these shocks legal, getting the overall and compression lengths correct. However, we are getting closer and should have them on the car for nats. Whether or not they'll be dialed in correctly is a different story...

I'm in the same boat....shocks finally arrived a couple weeks back, and have been struggling with getting them corrected, had to send the rears back and they needed to replace the cylinder with a longer one to make the length legal. Had to do some tinkering on the fronts as well, but they are all sized correctly now and got them on the car this past weekend finally. I have 2 local events before Nats to try and get them dialed in....assuming they are valved correctly, otherwise its back to stock shocks. Sure woulda been nice to have these back in July though

At least you guys will have the fit and valving figured out by the time I go to order them over the winter! Thanks for being the guinea pigs

Now I just need someone to figure out if 315s will work in the front

well then, since we were the guinea pigs for the shocks, i think its only fair for you to be the guinea pig for trying to get 315's working on the front

[ChrisSlicks]

I'm sure I could make 315's work but they wouldn't be on the stock 9" rim unfortunately. 315 on a 10" works.

The only reason I'm tempted to try on the 9" wheel is that I've seen C6 Vette guys running 315/30/18 on an 18x8.5" wheel. They said it gripped as well as the 295 but had much better wear characteristics. The Hoosier spec sheet even says they're the same diameter as the 295/30. With a stock legal 5mm spacer, I think there's a good chance they'll clear on the inside.

Fair?!?! Who said anything about fair? When I try it in the spring, you'll be the first to see how it works. It'll probably be with 315s in front and 295s in rear for the first event
