The Official 370Z Autocross Thread

[cotizi]

When I was looking i found getting stock class replacements besides stock wheels to be difficult. Im sure another set of stockers will show up, probably for less than 1K as well.

[AutoX Z]

I have an extra set of stockers and if I need a third set I'll probably buy something else to use everyday and then use my original stockers for race tires. I haven't been able to find anything in the stock sizes.

Nice job 'Ruff' on your tour event this past weekend at Wendover! Looks like you had a tough time on the first day, but a good result.

Thanks, car broke saturday and was broken on my runs, lol, so I had no chance. Made some bandaid fixes on saturday night, and as your saw, took top time in class on sunday. Had the car not broke, no doubt in my mind I would have taken the win. But battling back like I did, given the circumstances, I'll take it!

On a side note.....drove against 'Junior' this past weekend and about 5/10's off his pace, but am getting the feel for the car much better. This was actually my first "good" event in the car, as the previous 3 were under less than ideal conditions weather wise. None the less, having been out of the game for the past two years, I'm feeling pretty good about the upcoming season

In my opinion, this is not a BS car as it sits though....as a good BS driver in a Solstice was a good couple seconds ahead on each of the two days. He won PAX for the event, with several Nat Champs in attendance so he was on his game.

The Z's diff is what kills it....with CONSTANT inside wheel spin. With shocks, it may get a little better, but it ain't on par with the top BS cars as it sits....

NE Divisional in two weeks!

Isn't it a CS car?

Yes, it's CS....but there are those who say "it's a BS car, should be moved from CS" so I was trying to say that I don't think that's the case....or at least it wouldn't be a top BS car if moved....a back marker at best.

Having not run against any National level RX8 or MSR yet, can't say how it is in class (CS) against the them though.....is it an overdog? Probably not....a contender, yeah

What's Junior driving these days?

I totally agree with you about the stock diff. It is fine with street tires, but with race rubber the inside wheel gets too light and you get wheel spin. Usually you will also see the flashing slip light from the traction control as it starts to brake the spinning wheel.

[cossie1600]

I think only the Nismo is BS.

A former national champ drove the car, he believes the car should be competitive for CS, not sure if it will dominate. He loves the shorter wheelbase, but cant stand the LSD as it gives tons of inside wheel lift, even on the RE11. It will only get worse on A6

[AutoX Z]

That's weird, I'm not really experiencing any bad inside wheel spin after installing the hotchkis front bar. I know pgrmstr has the same set-up so I'm surprised to here that complaint from you. What kinda surface do yall usually run on?

[Ruff]

Food for thought, heitkotter and beitzer both raw timed me in Cali... All the 370 nay Sayers out there need to worry more about those two guys rather then a new unknown car.

pretty sure 'junior' will be in the ASP vette for the big events, but drives Learic's Z occasionally locally. They were both up to Philly this past weekend for our annual 2 day charity event...

I don't see any slip light, or at least I don't notice, but I know the car is not applying any brake to that spinning wheel.....I assume your VDC is OFF when running?

We don't have concrete out here....but it does seem to be course grip related....On Sat, we were on one lot and everyone was complaining of push (use Z folks included) and we had tons of wheel spin. It was a technical course where you really had to give it up to get around cones, and coming out of corners...getting on the gas hard really lit up the inside wheel. On Sun, we were on a different lot with much more grip. The course was much more flowing....and with the additional grip, we didn't get the push we were seeing on Sat and the wheel spin was much less...

Food for thought, heitkotter and beitzer both raw timed me in Cali... All the 370 nay Sayers out there need to worry more about those two guys rather then a new unknown car.

yeah, I noticed that......course dependent situation? Or are those guys that fast? Having run both the 350z and the GXP, how do the two compare on course?

Yes my VDC is off, but even with VDC off traction control can kick in if it sees a lot of wheel spin at the rear wheels. I only see it kick in if I get inside wheel spin, if both wheels spin then it doesn't kick in. Perhaps your stock VSLD is toasted and has turned into a peg leg? A few of the track guys have reported killing theirs. Mine still works but I haven't had any co-drivers.

Hmmmm.....perhaps I am staying under the "lots" of wheelspin threshold...as in the difference of rotation from one side to the other. If I get it, I will ease off slightly...but I can keep that 10% slip for quite awhile so I know the brakes aren't kicking in.

my LSD is fine, as I can induce both wheels to spin and drift the rear at will...my car only has 6,000 miles.....and only 4 auto events on it with a single driver

Sounds like your diff is okay then. My car also only has 6000 miles but closer to 20 events and so far seems to be holding up.

I only see the wheel slip light in certain corners that lighten the rear wheel, but it was definitely easy to reproduce on race tires especially on the first run. After the tires had some temperature it didn't seem to be as frequent.
