StopTech Big Brake Kits exceed stock performance in two key areas: First; larger rotors increase heat capacity; allowing a driver to brake harder stop-after-stop with reduced chance of fade. Second; stiffer calipers and stainless steel lines reduce system compliance; providing consistent pedal feel and confidence-inspiring responsiveness. The key; however; is to increase heat capacity and reduce compliance without upsetting a vehicle's stock front-to-rear brake torque ratio. That is why StopTech(R) developed the Balanced Brake Upgrade design philosophy; which precisely apportions front and rear braking resources while factoring in vehicle weight transfer under braking. Every StopTech Balanced Big Brake Kit is engineered to produce that optimal balance using caliper bores and pistons specifically selected and tested for each vehicle application. This is what sets StopTech apart from off-the-shelf solutions. In contrast; a brake upgrade that adds too much front torque as many do; will reduce your car's ability to maximize the traction available from all four tires; robbing you of performance. In addition; a system that uses too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate; limiting a driver's control of brake input.
