The Black Label Racing (BLR) Super 6-pot big brake kit is made out of forged aluminum. This is to dissipate heat under extreme braking temperature, to reduce brake fade when under racing conditions. To keep unsprung rate down to a minimum, forged aluminum is used as the material for this caliper. This complete kit includes the following: 2-piece cross-drilled 35mm/14" rotors x2, two big 6-pot lightweight forged aluminum calipers, caliper adaptor brackets x2, caliper mounting hardware, extended wheel studs, steel braided lines x2, a set of bleeder hoses, a complete set of street pads (blue), and a complete set of semi-race pads (pink). Brake kits available in anodized black, gold, or bronze color.
