These kits offer superior stopping power for your Porsche. With calipers that have larger pistons, the same or larger pad area as the Big Red Turbo calipers, and increased rotor diameters, over 2" in some applications, our Evolution brake kits can make a real difference in the brake performance for your Porsche. Other benefits include less unsprung weight due to the 2-piece, floating rotor design; the 355mm rotors offer an exceptional visual impact, filling up an 18" wheel! These kits include oversized 4 piston calipers, full 'floating' rotors and hat assemblies with billet aluminum hats and McLaren anti-rattle clips, hi-performance Brembo/Pagid brake pads, and all necessary adapters and hardware for installation.
