The Rocket Booster features a uniquely designed outer rim that creates a longer spoke and maximizes the view of your big brakes and suspension. Unlike polished wheels that require constant maintenance the Rocket Booster’s durable chrome finish comes from a multi-step dipping process that will last for years. When the wheels get dirty, simply hose them off and towel dry. The Rocket Booster Chrome is available in 17” and 18” diameters and they are offered in a variety of width and backspacing options. All RPM wheels are made from A356 aluminum and are designed and tested to meet or exceed U.S. D.O.T. requirements and SAE standards. Vintage style aluminum O-ring center caps are also included. The Booster is also available with Gray or Silver painted centers with machined outer rims. Prices start at $240.00 for a 17 X 7 wheel. Contact RPM at (888) 307-7525 www.rocketracingwheels.com
