Congrats Daniel, goodluck at the future events!

I don't know Pedroza....but he placed 3rd in PAX.....so considering you weren't too far off on raw time, and the lack of development or shocks on the car....it looks good for the Z this season! .....and congrats on the contingency Hoosier!

He kicked butt in CS last year, took 2nd to Buetzer...but Buetzer kinda dominated and I don't think was fully pushed lol

Pedroza has placed 2nd in CS the past 2 years and if I hadn't coned the 2nd day I would have PAX'd 17th so I know I didn't drive terribly but there was alot of sloppiness going on. Here are my best runs from each day:

[Ruff]

Damn those courses are awesome. Those are the type's I love and thrive on. I wish we could re-wind time and I'd co-drive with you at that event ahhhh! Pretty good driving man, glad you got second at least! Anyway, fun the limited amount of car I could see I think you need to work on your speed maintence in sweepers, granted I haven't driven the 370 yet, but the 350 will hang on like no other in sweepers, I just couldn't get it to dance in slaloms and tight transitions well. And you were late in some of the slaloms I saw, but over all pretty damn good man!

I agree, looks like there was lots of time out there in the sweepers....definitely better driving on day 2...much closer on the cones, as you appeared to be way off them on day 1. I was quite impressed this past sunday with the Z in the sweepers....and is where I picked up the time on each run. Get it hunkered down on the entry...get it turned in, and then I was on the gas for the entire sweeper. The Z just stuck and kept turning so no signs of push, just a little inside wheel spin, but nothing major and could easily be modulated with the gas peddle, but I was able to get on the power early on every sweeper and keep the line really nice, with a little sliding of the rear around the final cone of the sweeper as my foot planted solidly on the floor. I took last season off, didn't race much the year before, but looking forward to a full season this year....and after the 1st event, I am chomping at the bit to get back out there! Two weeks away and hopefully warmer weather. This is gonna be FUN!!!

Nice Job!

Nice course and nice job.

I'm surprised though that you were getting inside wheel spin. I don't experience that on an auto-x course, but it's probably because you're running A6's with stock suspension.

I get it even with DA Koni's... what's your setup Chris? It's mainly the crappy stock diff's fault

Stock struts and springs, Hotchkis swaybars, stock diff (for now). Probably the main difference is I'm only running RE-11's ATM. I'll be getting some different tires as the season warms up.

And you get you inside tire spin? I cook my re01rs when i run them.

No I very rarely get inside wheel spin, usually I can spin both rear tires if I want (and I'm in the power band) so this would indicate that my stock diff is still working ok. If any of you are co-driving perhaps you are overheating the diff?

[Ruff]

Lol, I think mine is just fried period.

[AutoX Z]

I never noticed inside wheel spin on street tires but the moment I started running on A6's it was everywhere. I've got a hotchkis front bar now and it's made a world of difference. I was able to get on the power much earlier and more confidently however I was still getting alot of push through the sweepers combined with some horrible lines cause I missed my braking points, hence the slowness.

I think the inside wheel spin on A6's is partially caused by them being much shorter then stock. So bad understeer eh? Iirc the Hotchkis is a pretty big bar for the 370 over stock, that might cause some understeer, but I'm betting still a worthwhile mod. Without shocks you're just going to have to drive around it. But one important factor is what tire pressures were you running? I noticed a feelable and drivable change on just a few pounds of difference.

[ChrisSlicks]

The Hotchkis front bar will cause pretty bad push as it reduces the body roll generated camber. Unfortunately I don't think there is much you can do to add static camber up front in stock class.
