Speaking of modifications for autocross purposes, what are the best things you can do to the Z and remain in SCCA B Stock? I already have better, wider tires, but as I look through the Solo rulebook, it seems to me I can't really change anything else. However, it's a bit cryptic.

 

Tires you can change, wheels must be the same size.

You can do a front sway bar
Shocks
catback exhaust

maybe a few other minor things, but those are the major items

 

whats the deal on adding a lip kit(body kit). Is that a no or a depends on how you read the rulebook on any given day.

 

On a National level, it's not allowed in the rules, no matter what day you read them (in b-stock). On a regional level, you may get away with it if no one else in the class cares.
