I've had problems correcting the understeer on the F1. I've solved some of it. So far, I've increased front camber, lowered ride height, more in front than rear, increased the rear to front ratios for spring rate, dampner, and roll bars, and lowered LSD sensitivity all around. I wanted to know if anyone was really happy with their setup and would post it. Thanks.
