The Official 370Z Autocross Thread

I've found the car cools the fastest between runs with the engine running, AC on full blast, and the hood open. Dual driving the car in the summer might be interesting but I think I can make it work.

And yes fuel starvation is a bitch and really prevents the car from getting the race weight down. I'm going to try and drop the muffler section at the next event I go to with sound and see if it still passes.

Anyone getting out there to more events?

I've had decent sucess in BS at both national events, 2nd at SD NT to the national champ, and then 3rd (just missed second by redlighting) at El Toro Pro again to the national champ. I gotta find more speed and get more use to the new car (non Z I know...).

Season is still in its infancy up here in the Northeast....we've only had three events so far....1st was cold in the 30's, 2nd was warm but a small dirty lot, and the 3rd was in the rain....so no real consistent seat time for me yet, but the national events in the area will begin within the month so its trial by fire for me...

I am running 265/285 RE11s. The setup seems to work okay except the car still tends to plow quite a bit, traction off the corners aren't an issue. If I could, I would try to get wider front tires. Of course it doesn't help our lots are tiny as hell

AutoX Z · 05-06-2010, 05:42 PM

We're 5 events into the season here. I'm undefeated locally but just picked up a co-driver so the competition should get alot better here soon. Just registered for the NT in Blytheville and got a fresh set of A6's on the way. Should get another good dose of national lvl competition with carter thompson.

Ruff · 05-06-2010, 06:54 PM

Good to hear everyone! I'll only get to do about 5 local events for the entire year, coupled with 7 national events. So not much practice for me! I have a great shot at getting a win in BS next weekend at Wendover NT.

AutoX Z · 05-08-2010, 08:37 AM

2 370's already registered for nationals, that anyone on here?

2 different 370z's...sick! Pretty sure Jeff is pgrmstr

My co-driver is signed up in BS, so we have our number. I'll wait until the last minute, kinda pissed at SCCA at the moment, so I really want to hold out on paying them.

AutoX Z · 05-10-2010, 07:41 AM

So what's everyone doing for rain tires? No Hoosier wets in 19's....

pgrmstr · 05-10-2010, 08:42 AM

Yeah, I registered this past week....and the other 370z is from my region, with two guys driving it but only one registered so far. the car owner is on here...but can't recall his screen name, and he's not very active.

That's me. And I just registered.

Welcome! Good luck at nats!

Has anyone noticed these wheels yet?
5-Zigen ProRacer ZR+520 - Gun Metal Wheels - Wheel Size & Price Details - 1010tires.com

By mid season I'll need a second set of race wheels to make tire rotation more practical and these seem like a real possibility since the supply of stock wheels for sale seems to have dried up. There's a 19x9 +42 which works in the stock allowance, and there's a 19x10 +38 which would work with one of those little 3mm spacers. They are about 5lbs per wheel heavier than stock, and a full set would run just over $1k. The 5zigen site specifically mentions that they will clear the brakes on the z34.

If I were to pick these up I could either run my old tires on them locally or use them for my street tires and use my original stock wheels for the second set of tires. Am I correct that these would be legal with spacers in the rear? And since I'm already pushing around 50lbs of unsprung weight, is another 5lbs going to really hurt?

This is the only set of aftermarket wheels (cheap/lightweight or otherwise) I've seen that would work in SCCA stock class. Are there any other options that I haven't noticed?

Running A6's at this point....otherwise its trying to find the best ST tire that comes in our size...although I am not rushing into doing that.

The way I see it, at the big events, if it rains, we're screwed....I don't care how good the street tire of choice may be, it won't keep up with Hoosier wets on an RX8 or MSR so I'm losing no sleep over getting something
