[s-cars] Autocross category for S4?

[Rich Assarabowski]

According to SCCA Solo II rules, the '92-94 S4 is classified as G-stock.
Interestingly, they do not list the '95 S6 anywhere (oversight?).  Does
anyone know what a chipped S4 with lowered suspension (Bilstein / H&R)
would be classified as?  STX or CSP?  Any personal experiences
autocrossing the S4's (stock or otherwise)??  What tire pressures??
