That probably isn't all of it either... these are pretty well balanced cars. What kind of track stuff are you doing?
It's a track day, running Intermediate with SCCA. Putnam Park in Indiana. I usually enter with no tire squeal and just add a little throttle until I start to hear the front tires, and then floor it off the apex. Not exactly the fastest approach, but again my car never oversteers. Square 245's, F: 7.5k, R:10k springs, 2.2 camber front, 1.9 rear. I'll be adding more front camber next time, maybe the car will balance out.

Once I floor it off an apex, I've only once had inside wheel peel. I don't have aftermarket bars, so this helps with putting power down. I am usually one of the faster cars in my run group, so I'm definitely pushing the car. I had to point by one driver last time, only after getting into fuel starve issues.

Maybe I should get a helical, being that this car isn't a full track car. Helicals don't add understeer like clutch type do, and still give you some lock. They also don't need serviced like clutch type do. I'm looking at MFactory diffs.
