The Rocket Booster Hyper Silver Center-Machined Outer 1 pc wheel was purpose built to deliver big style and performance for the finest muscle cars, pro-touring and street machines at very affordable prices. The Rocket Booster is precision-crafted from A356 aluminum and topped off with a vintage style aluminum o-ring center cap. The Hyper Silver Paint is a 2-stage finish that reflects light in a way that polished or chrome wheels cannot. You must see this wheel in person. The Booster is also available in Full Chrome as well as Gray Painted Centers with Machined Outers.
