GMP Performance sells performance parts from hundreds of different automotive companies. All GMP Performance invoices clearly state no returns on anything from mounted wheels, special orders items, to electrical items. Which basically mean you can not return anything to GMP Performance. One of GMP Performance's vendors is Wheel Power which manufacturer's Radenergie Wheels. Wheel Power does not take phone calls and only corresponds by email. Please be aware of these two companies because of their awful business practices. Radenergie wheels have also been known to have rivets fall off of their wheels allowing the wheels to fall apart. Thanks for your time.
