I've been taking my 02 Boxster S to the track and to Autocross, and it's got a few spots I'd like some advice in improving.
The car is on PSS9s with 225 RE71R up front and 255 RE71R in the rear. Current alignment is maxed camber front and rear, about -1.2 front and -2.2 rear, mild toe out front, mild toe in rear.
I've noticed the car is very harsh on the outsides of the tires, especially the front. That's getting better as I reduce over-driving, but a couple really hot laps will have a very noticeable effect on the tread shoulders.
- Are GT3 LCAs really necessary for more camber or will camber plates get most of the way there?
- Which wheel size and offset do I need to get a 255 or 245 on the front?
- Are poly bushings recommended? My car keeps coming out of alignment, even without any wheel-cracking potholes
