2016 SCCA Solo/Autocross PAX Index

11 Dec , 2015   David  

Yup it’s that time of year when some sort of formula determines how each SCCA Autocross will compare to another class. After a full year of stock class cars being on street tires there have been some changes that should make things more accurate. CSP, STF and SMF also had some rather large adjustments. Also of note is the addition of a new Street Touring class, STP.
