Torrance, Calif--StopTech LLC announces the first brake upgrade kit for the popular 2000 Bi-Turbo Audi S4 sedan as the latest addition to its Application Specific Big Brake Kits.

The new front brake system includes a set of 332mm high performance AeroRotorsTM with 7075 T-6 billet aluminum hats, a set of four piston high performance ST-40 calipers, Audi S4 caliper adapter brackets, high performance brake pads and front stainless steel braided brake lines. The STOPTECH Audi S4 kit is a direct bolt on replacement of the stock front system with no modifications required to the cars chassis or suspension and fits inside the Stock Audi S4 Bi-turbo 17-inch wheels. Extensive testing reports indicate improvement in stopping distances and greater heat capacity over the OE brake system.

Incorporating a unique patent pending directional vane design, the two-piece AeroRotorsTM provide dramatically improved induced airflow (over 60%) versus the straight vane stock rotor. Higher induced airflow means cooler operating temperatures under normal and aggressive driving conditions. Better cooling means longer pad and rotor life and a brake system that dramatically reduces fade. AeroRotor features a proprietary cast iron formula that resists cracking and fatigue. The two-piece AeroRotor includes a floating hat system that resists warping during heating and cooling cycles.

The ST-40 Caliper features a patent pending bridge that makes the caliper up to three times stiffer than similar designs. The ST-40 caliper is available with eight different piston sizes thus allowing selection of an Application Specific differential piston set matched to the Audi master cylinder. By designing the optimum piston size combination for the Audi S4 master cylinder the StopTech brake upgrade kit enables better modulation of the brakes than competitive systems.

The retail price for the Audi S4 Brake System: $1,995. Optional extras include red painted calipers for an additional $200 and an optional rear stainless steel braided brake line kit for $100.
