Overview

The Yellow Speed Racing Front 8 Piston Ultra Big Brake Kit is a performance upgrade designed for road and track use. It offers improved braking performance and faster response.

This kit is a direct bolt-on modification and includes forged billet aluminum calipers, two-piece rotors, high-performance brake pads, stainless steel braided brake lines, and all necessary hardware. The calipers feature vented aluminum pistons for heat resistance, and the rotors are available in drilled, slotted, or drilled & slotted styles.

This essential upgrade combats brake fade caused by extreme temperatures encountered during track use, offering a significant improvement over factory brake systems. Beyond enhanced stopping power, this big brake kit contributes to unsprung weight reduction, extends service intervals, and simplifies brake maintenance. The kit features forged billet aluminum split design calipers with an anti-rust coating and vented aluminum pistons for superior heat transfer resistance. CNC machined steel caliper mounting brackets ensure a direct bolt-on installation. Buyers have the option to customize caliper color, finish, and etching for a personalized appearance. The specific kit provided is for the Front of the BMW 3 Series (G20) models from 2019-2024, featuring a 5x112mm lug pattern. Rotor sizes up to 356mm x 32mm are supported, and different caliper models (YSCPF8a and YSCPF8b) are available depending on the application. For those concerned about wheel fitment, YSR provides wheel templates for pre-purchase testing and can be contacted for assistance. It is recommended to use Motul 5.1 or RBF600 brake fluid with this kit. Please note that YSR Big Brake Kits are made to order, with an estimated manufacturing and shipping time of 15-25 business days.
