Stop-Tech  Kits gives your Acura that Super car look and feel, and exceeds stock performance in two areas. First, the Big-Brake Kits has larger rotors so they increase heat capacity. Second, the big-brake kits stiffer calipers and stainless steel lines reduce the systems compliance.The key, however, is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratio. If the Big-brake kits upgrade you select ,adds too much front torque, you will reduce your Acura's ability to utilize the traction capacity of all four tires to the maximum practical extent, and you therefore create performance sacrifices. In addition, too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate, which limits your control of brake input on the race track.

Balanced Big-Brake Kits, Upgrades with optimum brake bias, offers the shortest stopping distance with the best pedal feel . Patented big-brake Aero-Rotors are the best airflow available, these Big Brake kits rotors are the result in better cooling, less fade and longer Big-Brake rotor and pad life. The stiffest big-brake caliper kits with patented bridge results in better clamping under hard braking and less brake pad taper. Track testing of the new big-brake kits ensures optimum performance. The ST-40 and ST-45 -  four piston big-brake calipers for the front and rear are made of Squeeze Forged aluminum alloy, ALL finished parts are 100% leak down and pressure tested to 2500 PSI.
