Sport Category is intended for daily-driven street cars on tires with a treadwear rating of 200 or higher with simple bolt-on modifications.

Modifications typically allowed in Sport:

• OBD-based ECU reflashes
• Most wheels
• Single-adjustable fixed-perched shocks
• Lowering spring kits
• Some camber allowances for Strut-type suspension
• Direct-replacement sway bars
• Cold-air intakes
• Cat-back exhausts
• Radiator and fluid coolers
• Brake option packages and some cosmetic modifications from a different trim model of the vehicle—like swapping spoilers

Ultralight wheels, some types of aftermarket camber-adjustment, ride-height adjusting coilovers, racing springs, speedway-style sway bars, chassis bracing and aftermarket-ECU are not allowed. Click here to find the full Sport Category Rules.
