Yellow Speed Racing Front 6 Piston Ultra Big Brake Kit - Acura CL 2001-2003 (YA4)
Yellow Speed Racing’s Ultra Series Big Brake Kit is designed for road and track use. This big brake kit features optimum braking performance, attractive looks, easy installation and a cost-effective price.
Factory brakes are designed primarily for daily driving on most applications. If you have added additional horsepower to your vehicle, or frequently compete in motorsports such as circuit racing, drifting, time attack or rally racing, then a big brake kit is an essential upgrade to prevent brake fade that is commonly experienced with the extreme brake temperatures that result from track use.
By upgrading your factory brake system, not only do you improve braking performance, but other benefits include unsprung weight reduction, longer service intervals, as well as simpler brake maintenance. YSR's brake systems provide the driver with faster brake response, and maximum performance!
YSR big brake kits are a direct bolt-on modification, that requires common hand tools for proper installation on most vehicles. Customize your calipers color, finish and/or etching to give your vehicle a unique appearance.
