Car Classing

Basic car classing exists so drivers compete against those in similar cars and/or of a similar skill level. It is each competitor’s responsibility to class themselves correctly and to help class all other participants correctly. Yes that means it is each driver’s problem to read and understand this page. 🙂

If you swap your engine, add a supercharger/turbocharger, swap on a bigger turbo, run a very sticky tire, mount big aero, gut your interior, etc – your car moves from Street to Competition class and probably bumps from 1 to 2 or 2 to 3 (even if it’s still a daily driver!)


NOVICE CLASS is for first timers, beginners, and those fairly new to this (~5 or fewer autocrosses, trackcrosses, HPDEs, or similar performance driving events in the last few years) regardless of car.

EXPO CLASS is a catch-all for those who don’t care about car classing and/or don’t want the chance to win stuff. It is our “fun-run what ya brung” class and is not recognized in our points championship.

STREET CLASSES shall be for street legal production cars that are stock or have limited/basic bolt-on modifications like intakes or exhausts or springs/shocks, DOT 140+ treadwear street tires, full interiors, and little to no weight reduction:

SF1 = Street FWD under 2.5L naturally aspirated
SF2 = Street FWD over 2.5L NA + all forced induction, less than 400hp
SF3 = Street FWD over 2.5L NA + all forced induction, 400hp or more
SR1 = Street RWD under 2.5L naturally aspirated
SR2 = Street RWD over 2.5L NA + all forced induction, less than 400hp
SR3 = Street RWD over 2.5L NA + all forced induction, 400hp or more
SA1 = Street AWD under 2.5L naturally aspirated
SA2 = Street AWD over 2.5L NA + all forced induction, less than 400hp
SA3 = Street AWD over 2.5L NA + all forced induction, 400hp or more


COMPETITION CLASSES shall be for street legal or non street legal competition or racing prepared cars with more extensive modifications like engine swaps, head swaps, or added forced induction, DOT R-compound tires or full slicks or any tire with less than 140 treadwear, gutted interiors, significant aerodynamic aids, and/or significant weight reduction:

CF1 = Competition FWD under 2.5L naturally aspirated
CF2 = Comp FWD over 2.5L NA + all forced induction, less than 400hp
CF3 = Comp FWD over 2.5L NA + all forced induction, 400hp or more
CR1 = Competition RWD under 2.5L naturally aspirated
CR2 = Comp RWD over 2.5L NA + all forced induction, less than 400hp
CR3 = Comp RWD over 2.5L NA + all forced induction, 400hp or more
CA1 = Competition AWD under 2.5L naturally aspirated
CA2 = Comp AWD over 2.5L NA + all forced induction, less than 400hp
CA3 = Comp AWD over 2.5L NA + all forced induction, 400hp or more


Again… if you swap your engine, add a supercharger/turbocharger, swap on a bigger turbo, run a very sticky tire, mount big aero, gut your interior, etc – your car moves from Street to Competition class and probably bumps from 1 to 2 or 2 to 3 (even if it’s still a daily driver!)

Horsepower ratings for consideration above are at the crank, from manufacturer specifications and/or via best calculation on a dynamometer. If you have any questions about your power level or about which class to select, please contact Jon Felton before registering.
