Lots of thing to fix within SCCA stock rules:

1) A way stiffer front sway to keep the rear planted on turn exit
2) Choose a 6-speed not a 7-speed
3) Toe and camber settings
4) 19" A6 not 18", due to the larger diameter and better gearing with 19"
5) shocks
6) muffler bypass pipes
7) LW wheels
I understand everything other than the preference fro 19" wheels vs. 18". I've ordered my car with 19" wheels and found a set of 18" take-offs for my snow tires. I was also thinking that going to 18" with the lowest profile available would give me a higher numerical final drive ratio for autocross use. I'm thinking that the higher effective torque would be the way to go. Larger wheels, all other things being equal, reduce acceleration, IME.

Am I missing something?

Also, will the E9x meet sound restrictions with muffler bypass pipes???

I'm really curious to read what toe and camber settings can be achieved with the stock camber plates.
