I should think that, too.
But something keeps bugging me about the tires. I know there are some tires who don't need static camber, others that do.
And the Alfa suspension isn't exactly known for it's wonderful camber curves...
I wish I were a chassis dynamics guy sometimes, but powertrain systems pays the bills.
Max, I would consdier using your set up, but the problem is that I'm quite happy with my set up. So my next car will be much like it. I know you are conviced that the Red Konis are not up to snuff on the really stiff springs, but I can't seem to find that same problem. There are some occasions when autocrossing that the car wallows a little, but those tend also to be very tight 180's where I overdrive the corner, too.
On the track, even the very bumpy Waterford Hills, my car feels very stable. And the times are reasonably quick- my street car would have placed mid pack in it's run group at the last historic race I saw at the track. And at Gingerman, it would be similar- both about 3-4 seconds off of the pole time. (makes my chest fill out a lot, you know...
Review of my set up- W&D all the way around for springs- (I think that's 1200 front, 150 rear), Koni Red Shocks, Shankle front sway bar (27mm front mount), stock rear sway bar, 15x7 Panasports, normally wrapped with Kuhmo Victoracers, and -2.5deg camber in the front. When I put the cheap priced Hoosier Autocrossers on this past spring, those things were ROCKETS, but I wore through the tread way too fast. Good if I ever wanted to join George in Topica, but bad for the racer who likes valued based fun.
For the race car I will be building (someday, I swear it's not a dream), I will adjust the car to drive like the car above. Except for the lifting of the right rear tire on hard right corners, but that is another story.
