This will be the classing for Saturday:

Modified:
Any car with the following modifications will be classified as modified:
-R-Comp tires
-Any type of aftermarket forced induction.
-Coilovers
-More than one aftermarket strut bar
-More than one aftermarket sway bar

Stock:
Any car without the modifications causing it to be in the modified class will be classified as in the stock roadster class.
So your roadster must be:
-Naturally aspirated or turbo/SC from factory with factory settings
-Street tires
-Stock suspension (aftermarket shocks and springs are allowed in the stock class, but no more than one aftermarket strut or sway bar is allowed).
-Roll bars are allowed
-Performance bolt-on's are allowed

*Classing is subject to change*

Non-roadsters will be in their own class and running group.

Trophies will be given to the 1st place driver for both stock and modified.

Let me know if you have any questions about classing, I can either answer them via the forum, or in-person on Saturday.
