Boxster 986 Autocross/Track Setup

[Topless]

Adjustable GT3 Arms cost more than camber plates but you get what you pay for with a wider trac and better tuneability. Worth it to me.

If you don't plan to change the struts, the stock sways are ok. Changing to a M030 on the rear allows the car to rotate more easily without generating wheelspin.

RE-71R is the ideal AX tire for setting quick single laps.

I would probably stick with 17" stock wheels for track days and run NT01 in 225/255. I ran 20 sets of these on my 986 and they are just about the ideal tire for affordable continuous lapping. They hold up to heat much better than 888s.
