Arrow F82 M4 ZCP in SCCA Solo A Street Autocross

Looking for some feedback/tips/pointers/setup from anyone running in AS Class for autocross? Competition looks pretty tight against the vettes. Wanted to see what others had to share with their setup or alignment? Thanks!

settings

I found these settings to work well for AX and track:

-3.6 deg front camber
-0.4 deg front toe
-1.8 deg rear camber
0.8 deg rear toe

What suspension / tire setup do you run?

-3.6 up front sounds like slicks not street tires.

Not competitive against the Corvettes. I tried a whole season (20 events, 3 national tour events and the Pro Nationals). In AS your front camber is what you have and is not adjustable (mine was -1.6 L and -1.1 R) . I found that -1.5 rear camber with 3/8 toe in in the rear and 0 toe in the front was as good as it got. I ran 275 square RE71R on the stock 18 wheels. It would have been better on 295 rears but no decent autocross tires were available in the 295/18 size at that time (2016 season). It was fun, but not a competitive car in a class with cars that have a fully adjustable front suspension. It should be classed in FS....

There is a proposal which has the M3/M4 moving to BS which is out for comment. Keep your fingers cross as Kevin is a strong barometer of whether it can compete in AS. BS next year is going to very interesting with the 1LE and other proposed cars coming in if the proposal is approved.
