Mini-Tub Trunk Closeout Kit

The Mini-Tub Trunk Closeout Kit from Detroit Speed Engineering is designed for serious hot rodders and street machine builders who require maximum tire clearance while preserving trunk storage and structural integrity. This kit enables the installation of larger diameter wheels and tires in classic and modern muscle cars, eliminating the need for expensive full-frame modifications.

The mini-tub design incorporates precision-formed steel components that integrate seamlessly with the existing trunk floor geometry. This design reduces unsprung weight compared to full-tub conversions while maintaining chassis rigidity. The kit features CAD-verified panel contours and factory-style welding flanges, allowing skilled fabricators to achieve an OEM-quality fit and finish without extensive cutting or reinforcement.

Ideal for builders working on Chevrolet, Pontiac, Buick, Oldsmobile, and Dodge platforms from the 1960s through the 1980s, this closeout kit supports wheel sizes up to 19 inches in diameter. At a weight of 9.45 pounds, it adds minimal weight, crucial for maintaining your vehicle's handling balance and acceleration characteristics.
