I have stock front and FHI 20mm rear with Whiteline KLC26 endlinks on my '01 RS. I think the setup is perfect for street and track use, but I am installing a whiteline adjustable for autocross, where rotation is more important. Also, take your alignment into account to control how much over/understeer you have. I have kind of a crazy setup right now- 1.6 degrees of camber up front, 0 toe, and 2.5 degrees camber in the rear with 1/16th toe out. Makes the car incredibly stable on the racetrack at high speeds without creating resistance on turn-in. Like I said though, for autocross, I'm going to need a bigger RSB to get the rear to step out at lower speeds.
