NeoGen air pressure

Thanks for your help.

btw- I've got to travel for ??? long. So if there are any more thoughts, I'm not ignoring you, I'll respond as soon as I return.

I think your on the right track now I more spring and rebound in the rear will help with rotation. Also I would try running a higher tire pressure in the rear then the front this will also add some more rotation.

Wonder what the Koni spring rates are?

The rotation thing- for as much as the front tires are being ripped apart, the rears look pristine, with no evidence of even rolling under. These look like grandma's tires. That's not right, is it? If rotation is happening, then shouldn't I see at least a little evidence of it in the form of rear tire wear?

You should see at least a little evidence of tire scrub on the rears.

At your next event, talk to some of the more advance FWD drivers and see if one of them will take your car for a lap or two and give you some feedback on your setup (With you riding along of course). At the same time, you can see how your car behaves with a more experienced autocrosser at the wheel.

If you're not comfortable with someone else driving your car, get one of these guys to ride along with you and critique your driving.

^^^Good suggestion.

By all means, the fronts take about 80% of the abuse on an AutoCross course.
With that in mind, I rotate my AC tires each event to get more even wear.

As I mentioned earlier...
The sooner you burn through those NeoGens the sooner you'll get some better tires on there.

^^ Ok then, so I figured I have to have 45 up front to keep the tires from rolling under, that's a given, and the back has to be equally hard to loosen it and neutralize the understeer. I went with 45 front, 43 back, and the shocks full soft front, half hard back. After 2 runs, it seemed really good. Later, for other reasons, I had an instructor drive the car (he litterly shook the change out of my pockets- wow!) The topic of the car never came up, we were concerned with tecnique, etc, but as he walked away, he said, "By the way, that thing is set up beautyfully." So- Problem over! Thanks to everybody for your help!

I'm glad we could help. Sounds like things are coming nicely. Enjoy the rest of the season!!!
