AP Racing Big Brake Kits
Whether your pushing it on the track or just driving on the road, your brakes should be performing at their best, and the best means AP Racing. The same company who continuously supplied championship winning teams in Formula 1, NASCAR, LeMans, FIA GT, ALMS, LMES, Grand Am, Super GT, BTCC, DTM, etc. In nearly all types of serious motor racing around the world, AP Racing gets the call more often when only the best will survive.

When Ultima Sports needed a brake system for their multiple world record holding 200mph street-driven Ultima GTR super car, they knew who to call. Their all conquering AP Racing equipped Ultima GTR has, for the third consecutive year, smashed the world record for sprinting to 100mph and back to zero again in a gut wrenching 9.4 seconds That is .5 second FASTER than the Bugatti Veyron and a blistering 1.5 seconds FASTER than the Ferrari Enzo! All of this was done in the daily-driven factory demonstrator with street tires and no ABS or traction control!

Track professionals understand the need for absolute control. AP Racing understands how to give that same control to your Audi A4!

General Benefits of Big Brake Kits

Original Equipment (OE) brake systems do the job they were intended to, stop safely and quietly for the lowest cost possible. After adding performance upgrades, while towing, or just having some fun in the canyons, OE brakes are often overwhelmed by heat when the moment of truth arrives.

Big Brake Kits give your vehicle that super car look and feel, while significantly improving your brake performance in two areas. First, larger brake discs increase heat capacity, meaning your brakes will be more resistant to brake fade. Second, stiffer calipers and brake lines increase pedal feel and modulation.
AP Racing 4-Piston Big Brake Kits
For a big upgrade at an affordable price, Brake Pros offers world renown AP Racing 4-piston calipers running on 1-piece and/or 2-piece rotors. Each kit is designed to work with the original equipment master cylinder, ABS and traction control systems. Specially-designed rotors are cross-drilled and slotted, the optimum for high-performance street, autocross and occasional track day use. The curved vane construction provides for maximum cooling when pushing hard. 2-piece kits come with aluminum alloy hats for better thermal management and maximum weight reduction.

(4-Piston Kits use 330x25.5 rotors)
