Tuner Category is intended for street-driven vehicles on tires with a treadwear rating of 200 or higher with bolt-on modifications that allow for tuning and adjustment. Everything still has to bolt to the stock places, but this is where you will find the ability to include the following:

• Intercoolers and boost controllers on forced induction cars
• Headers
• Caster/camber plates
• Ride-height adjustable coilovers
• Racing springs
• Highly tunable sway bars
• Aftermarket ECUs for non-OBD cars
• Aftermarket big brake kits
