APR 6-Piston Front Big Brake Kit 370x34mm - Audi S3 / Volkswagen Golf R / GTI (MQB) 2015-2025 - Grey

APR's 370x34mm 6-piston big brake kit is a front axle upgrade built around billet aluminum calipers with stainless steel pistons and a maximum temperature recording system, so pads and fluid can be matched to what the brakes actually see. Two-piece 370x34mm semi-floating slotted discs run 72 curved directional cooling vanes, and the kit ships with high-performance street pads in a standard replacement shape, braided stainless steel brake lines, billet caliper mounting brackets and all the install hardware. Because the system is sized for the specific vehicle it holds the correct brake bias and works properly with the ABS and stability control under emergency braking.
