The Official 370Z Autocross Thread

Could anyone help me out? My auto-x club, Capital Driving Club, does not use SCCA classifications.

However, I signed up for the October 9, 2010 SCCA event at Fed Ex and I am not sure what class I should be in.

My modifications are:

1. Oil Cooler.
2. Brake Ducts.
3. Carbo Tech Pads.

Thanks in advance.

Pads are free. Oil cooler and brake ducts technically bump you to SP even though they don't enhance your auto-x performance. Given the limited mods you could run stock and nobody would care, I doubt you would get any challenge unless this was a regional event.

Thanks for the response.

Actually, I had the date wrong. It is the Washington D.C. Region SCCA, Inc.
WDCR Solo Championship Event #7 Autocross/Solo II on Sunday, October 03, 2010.

I am running on street tires (RE-11's) and I doubt that I would be fast enough to bring on any unwanted attention. But I don't want to cause a scene.

What do you think?

dont ask dont tell!

[cossie1600]

you will be fine, just dont say anything

i dont know what your skill level is, but its going to be a uphill battle with no slicks regardless. the re11 can definitely hold its own, but just not against a6s

[ResIpsa]

C Stock it will be!

Thanks for the help.

here is my most recent video... i know not a 370z but i feel at home here so enjoy

went into limp mode with a clutch overheat for 3 secs at 1:45 but still salvaged the run

[cossie1600]

Was it really a two minute course? Holy $hit.

yeah like 1:45-1:50ishish i think that run was 109 seconds with the limp mode.. my best was a 106 sec but like i said i went on the wrong side of a gate so DNFed....

we do two of those a year.. they are called trialcrosses around here and you can get up to 70ish mph... the others are the usual 30-40-50 sec courses...


a long course like that is hard on the tires and its alot to mentally remember... you can hear my passenger say all the way over as i he was reminding me of a gate that i had missed the run before and i forgot it was there and just made it straight line

[ChrisSlicks]

Looks to be a similar size to the course we run, except we use 3 runways so we don't have to do double backs. We used to make them really long, about 2m30s, but now we probably average 1:40 to 1:50. It does take it to the next level in terms of car abuse and driver memorization skills. For the first 3 runs you gain 6psi of pressure each run, without a cooler oil temps hit 260F each run. If you co-drive in the same run group you hit limp mode.

[cossie1600]

I do have to admit. THe course was a typical airstrip course. It had way too many slaloms, not enough of other things. I was getting dizzy rocking left and right watching your video.

You guys are lucky, this is the BS we get here locally.

On a side note, how much camber can you guys get on a stock car? I havent done an alignment, but just curious to see what I will see on the machine.

Holy crap that is tight. That had to be the worlds shortest stop box as well, LOL.

If you have factory suspension you have no adjustment and no way to gain. I think my stock alignment was around -1.0.

yup, that's the kind of BS we have here. It's either make the 2.5 hours drive or do the peanut size lots.

Eibach listed some camber bolts for the 370z? Is that really camber bolts or new camber plates?

Also what is the best front bar for this car, the Hotchikins?

This is the other lot we run, just as small. http://www.youtube.com/watch?v=csMS72kgoYI

[ChrisSlicks]

Wow for a while there I thought it was like the Nascar of Auto-x, you only turned left!

I believe the Eibach part is a replacement upper control arm.

As far as best front sway, there is probably some distributed opinion on this. I had the Hotchkis front sway bar with stock suspension but felt it introduced too much understeer, although it works well with coilovers and an adjustable control arm. If I was replacing just the front bar I guess I would lean towards the Stillen or the Whiteline as they aren't quite as stiff. I think the Whiteline may even have 2 adjustment settings.
