The Official 370Z Autocross Thread

[Dcocci]

Sooo LOL @ autocrossing with a 370 base with factory wheels and tires. Talk about zero grip anywhere. I went there to shake the car down before I start modding it, and by the first half run I knew EXACTLY where to start. Wheels n tires plz. The car has sooo much more to offer with a simple wheel and tire upgrade. Just venting fellas

Running on 285 35 19 Kumho XS square, my alignment rear camber is -1.7, toe is at .16. I ran my first event yesterday in my 370z, the lot we run at was recently re-sealed and a little slick but I have been running a srt-6 which has a little more torque and no lsd. My question is what are some of your rear alignment specs, the rear end was all over the place yesterday, front had a good amount of grip, I found running 36f and 33r was helping. My question is what do you guys recommend to get a little rear grip in the car, my rears are a little old, not heat cycled or worn out but ill go to a 305 rs-3 next which i think should help. What may you guys recommend to me? alignment specs maybe?

going from 285's to 305's would already give you a nice change, especially with rs3's. I'd mount them first and see how it feels, and if you still aren't satisfied look into changing around the alignment. What are you running for suspension and swaybars?

I am 100% stock, first autocross in the car, just felt more loose then it should have been to me

Sticky tires and learning when to modulate the gas. You could do a front sway bar too, but I'd suggest getting a good feel for the car without one for a season first. Also, what was the temp where you were? That can have a drastic affect on tires.

I was running a275/305 rs-3 setup and though it felt pretty good, but then I changed to stock 245/275 zii's and it was so much better. I'm stock as well but planning on doing shocks and a front sway bar next season.

hahaha I JUST went through the same thing in my Z! I myself am trying wider wheels and tires first before anything else. I'm considering an 18x10.5 wheel and 275-285 wide tire setup all around, or a "square" setup as i've seen it called.

I for one would like to see someone finally do a rulebook 370z for ASP....

Slowly but surely I'm working on it. Unfortunately the bank account only goes so far for any one off season. Hopefully after this winter the car will be what I at least would consider 80-85% rulebook.

Still trying to decide on whether ditching the factory Nismo wing for a proper spoiler is the way to go or not.

Do aero last...

Since I was gone for most of the year I only had the chance to run two events in the New Z. PSS's are not the best but it's all I have right now. It was nice running a stock car again since I was able to pick up on some bad techniques that I had to quickly fix. The PSS's did pretty well in the last event since it as cold but I'm switching to Rivals next year. Who here is running ASP? I'm planning on running that next year. Took a 2nd and 1st in my last two events in BS but it looks like the Nismo is going to AS next season.

I'm running ASP. Will most likely being doing Toledo, Wilmington, and Peru national events next season and hopefully a trip out to Lincoln assuming I can find a way to get the car out there that doesn't include driving it out.

What did you do to make the car competitive? For next season 18" wheels and tires is the main goal and I want to run a 275 up front min. The Z is stock right now minus a oil cooler and exhaust. I was glad that I was beating up on camaros and a boss after only two events but I did notice a decent difference in how the Nismo handled over my old one.

[gomer_110]

I run 315/30-18 Hoosiers on all 4 corners. Car is full breather mods, Uprev tuned, upgraded drivetrain (LSD, flywheel, etc), 2 pc rotors + carbotech pads, upgraded sway bars, front upper control arms, AST single adjust dampers with the factory Nismo springs. The shocks and springs will be getting replaced this off season along with the addition of adjustable rear spring perches and camber arms.

Which LSD did you go with Gomer? That may be next on the list for me. I'm running ASP as well. Thankfully I've barely been able to hang onto my cars daily drivability. Just did KW coils and a new clutch/flywheel this season so far. I know it's not the best coilover for racing but the adjustability is nice and it's been a good compromise for street driving as well.

[gomer_110]

I have a quaife in mine. In the grand scheme of things I probably should have gone with a clutch type LSD but for now I'm not too worried about it. Still need to do a lot more work on the nut behind the wheel before I worry about the finer details.
