RPM Wheels - Chrome 20 inch rims from RPM @ Wheelstudio.com - The all chrome RMP M-511 is a six spoke design with several styling touches. The spokes have a raised center that becomes as wide as the rest of the spoke as they arch their way to a deep lip. The lip is lined with simulated rivets between the spokes for a multi-piece look. A chrome center cap keeps the face of the wheel from becoming too busy, and matches the mirror-like finish of the rest of the wheel.
