Outlaw M-16 Features

Hybrid design combines the lightweight, small body, four-piston 2000 series caliper with 3.50” spacing and mounting ears of the rugged 3000 series caliper.
Thicker pad than the 2000 series. Integrates a bridge bolt for pad retention and further increases housing rigidity.
Dual center bridge bolts. (Reduce caliper flex).
Superior in strength to cast calipers.
Stainless steel pistons. Retards heat transfer to brake fluid.
High temperature, square cut piston seals. Controls piston retraction for zero drag.
Internal crossover brake fluid passage. Eliminates potential crossover tube damage from debris.
Perfect for front and rear axles on dirt track cars, rear axle on late model asphalt cars and rear inboard on sprint cars.
