Wow, those settings really helped. Thing is, they really weren't all that different from what I was doing (rear softer sprung, front with more camber, rears with some toe-in). But I was running considerably softer springs as I've been racing Nuremberg a lot and it is brutal. It's amazing how much of a difference those specific settings made even though I was working along the same lines.
Also, the brake controller settings worked like a charm, the car now steers while braking instead of trying to go straight ahead. I tried similar settings on my Lotus Elise and it now steers while braking much better than it did. My tires also wear more evenly. Now, call me stupid, but I never tried adjusting the brakes for more power in the front - I always just assumed it would cause the front wheels to lock more easily and then you get no steering at all. I had tried the opposite (more power to rear brakes), it didn't help, and I gave up on the brake controller and just went with racing brakes. I expect I'll be spending some time next week playing with brake settings on all my favorite cars.
I did make a couple changes to the suggested settings. For one thing, the settings appear to be for GT3, so in some cases I had to choose the closest setting possible.
P.S. Thanks again for the help. I've read many of the tuning guides, but most of them try to combine the theory of the game physics with Real Life physics, which can cause some confusion. Someone who really knows his stuff should write up a short, concise, 2 or 3 page guide that simply states what works in the game to solve common handling issues.....
