Autocross questions

IMWEZL · 02-05-2012, 07:51 PM

I'm probably just going to run on my RE-11s. I'm thinking I'll have to run in CSP since I have a catback and oil cooler. Running in stock in Hawaii two years ago was awesome. There was an RX8 running on A6s which made for great competition during the season.

I'm looking forward to get back into autocrossing!

Whoops forgot about the change.

Yeah it's been awhile. ASP as in GTRs and Vettes? Anyone have a 2012 classification listing?

Re-11s are solid for autox, I drive an hour each way to autocross on mine.

ASP for Nismo, BSP for non Nismo

Incorrect. ASP specifically states all 370Z. They are only differentiated in the stock classes.

No vettes in ASP now. SSP was beefed up to include the GTR and ASP mostly resembles old BSP with Porsches (minus current turbos), Evo/Subie, and that GXP.

Now that you have me looking at it again, it's not as bad as I thought. Maybe I'll be up to ASP before the 2013 season. Need that camber on the track!

IMWEZL · 02-06-2012, 09:35 AM

Eh that's not too bad. I'm competitive but not to the point where I won't enjoy the race and participation.

03threefiftyz · 02-06-2012, 09:35 AM

All 370's are in ASP as mentioned. ASP is Evo's, STI's, skystices, and franken-boxsters. The 370 wouldn't be separated in street prepared.....that's why we have update/backdate in our rule set.

Oh sorry

Any thoughts about running a bigger staggered setup vs. a square like 285/35/18's on 18x10.5 rims w/ 25mm spacer in rear? (uh oh ...)

It a heavy car that needs a lot of tire but it needs it more on the front. Running a staggered set-up can only result in lots of understeer. I think the trick will be fitting 315's square without having to cut/flare the front fenders.

Curious what you are basing this on? I have been driving prepared cars etc for a long time and well setup 370z on staggered setup is completely nueteral from what I have seen. I experience very little understeer with 295/315 stagger. I think for average ax driver staggered will work fine if you have flexibility to use differnt suspension setup than stock.

I don't think shoving a 315 under front is going to accomplish much and for people in cooler regions I'd argue solo driver will have issues with getting that much tire warm.

I will be experimenting however I don't think a well setup car on mild 295/315 stagger will see as much understeer as you think. If anything my car tends to have a little oversteer. But I base this from running mostly cool venues as a single driver. Just wish more serious ax guys were trying SP/SSM mods.

A two driver car on warm surface may in fact benefit from 315 upfront. But honestly if I go to 315 front I'm going to 335 rear.

Not lacking for power, the trend is to run as much tire as possible. Shamu, who is the most serious ASP contender we have, was going out to 12" in the rear.

03threefiftyz · 02-06-2012, 01:45 PM

I'll have 18x12's and 315's on all 4 of my 350 in the very near future, but will only be on 285's (18x10.5's) for the Dixie Tour and DC Pro. I have a set of sticker 285's to burn up.
