DSE Mini-Tubs (040403DS) - 1970-1981 Chevrolet Camaro / Pontiac Firebird
Put serious rear tire under your second-generation F-Body while maintaining a clean, factory-style appearance with Detroit Speed Mini-Tubs. Designed specifically for 1970-1981 Chevrolet Camaro and Pontiac Firebird applications, part number 040403DS replaces the factory inner wheel housings with wider stamped-steel tubs engineered to accommodate tires up to 335mm wide. At 2-1/2 inches wider than stock, these Mini-Tubs give performance-oriented street, Pro Touring, and track builds the additional rear tire clearance needed to make better use of available traction.
Detroit Speed stamps these Mini-Tubs from durable 18-gauge steel with an OE-style appearance designed to integrate cleanly with the original body structure. The kit includes driver- and passenger-side Mini-Tubs, laser-cut front and rear wheelwell flanges for both sides, five installation templates, and instructions. A narrowed fuel tank is required and available separately. Manufactured in the USA, these vehicle-specific Mini-Tubs eliminate much of the fabrication involved in building custom wheel tubs from scratch while delivering a professional finished appearance.
