I’ve heard that "performance" modifications can void an auto insurance policy. Is this true? If so, what is considered a void worthy mod?
I know that my coverage will only replace the parts to stock. Also, I’m planning on the following: CAI, headers & exhaust, short shifter, big breaks, ECU programing. When my shocks are due to be replaced i’ll probably take the opportunity to ride lower.

anything that may potentially endanger the driver, the vehicle or the vehicles around you, things like installing nitrous oxide tanks, a turbo, sometimes removing ABS brakes

thing as changing brakes, tuning and recalibrating the suspension are normally ok, read your auto-insurance contract before making any modifications
