Installing aftermarket parts may void certain aspects of your vehicle's warranty, so it's always a good idea to check with your dealership or manufacturer before making any modifications. However, Kartboy parts are designed to be compatible with factory components and should not cause any issues with your vehicle's warranty.
While Kartboy parts are designed to improve performance on the race track, they are also perfectly suitable for daily driving. In fact, many Kartboy customers use their products primarily for street use and have noticed significant improvements in handling and drivability.
Kartboy parts can be purchased directly from the company's website or through authorized dealers and distributors. A list of authorized dealers and distributors can be found on the Kartboy website.
