Aftermarket intercooler = Street Modified 2, or SM2 (since it's a two-seater)
Stock tires = Street Tire 1 category
so, SM2/ST1
or since you're new,
SM2 class and Novice 1 category.
More description of you mods might help better define your class. You may be legal for ASP if your intercooler fits in these parameters...
As utilized only on engines originally equipped with forced induction, induction charge heat exchangers (known as “intercoolers”
or “charge air coolers (CACs)”) are unrestricted in size and configuration. Air-to-air CACs and radiators for airto-liquid CACs must be cooled only by the atmosphere, except for standard parts. Body panels, fascias, or structural members may not be cut or altered to facilitate CAC installation.See you at the track, come early and bring plenty of water! Your car could be highly competitive in Novice 1, easily capable of top-three if you do your part.

Hi everyone!
I recently purchased an 08 Saturn Sky Redline and having a blast driving it. I was thinking about maybe bringing it to an event, but I was curious as to what class I'd be put into.
Everything on the car is stock (including tires, does that matter?) with exception to the intercooler, exhaust, downpipe, and a tune. I *think* that puts me in street prepared (per the checklist from the novice guide) but I just want to make sure.
Whenever I make it out to an event, it will be my first. I'm not looking to win anything, but just out of curiousity, what other cars are in this division and how bad would I get blown out of the water?
Thanks!
