Audi S4 StopTech Big Brake Kit
Fits: 1999-2002 Audi S4 (B5 Chassis) - Fits Stock Wheels
Several Caliper and Rotor Styles are Available!

StopTech Big Brake Kits Includes:
  • Calipers
  • 2 piece floating directional AeroRotors with hats (pre-assembled)
  • Stainless steel brake lines
  • Caliper mounting brackets
  • Street performance pads (suitable for both street and light track use, such as Autocross - 1 lap at a time)
  • Caliper color options in Red, Black, Silver, Yellow, and Blue
  • *Silver, Yellow, and Blue caliper options have a 30 day minimum shipment lead time.
  • Rotors are availabe in slotted or drilled styles.

    Big Brake Kits give your vehicle that Supercar look and feel, and exceed stock performance in two areas. First, larger rotors increase heat capacity. Second, stiffer calipers and stainless steel lines reduce system compliance.

    The key, however, is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratio. If the brake upgrade you select adds too much front torque (as many do), you reduce your car's ability to utilize the tractive capacity of all of the tires to the maximum practical extent (even on ABS equipped cars) 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 a driver's control of brake input on the race track.

    StopTech Advantages:
  • Shorter Stopping Distances
  • Better Brake Modulation
  • Firmer Brake Pedal
  • Less Brake Fade
  • Balanced Brake Upgrades with optimum brake bias offer the shortest stopping distance with the best pedal feel
  • Our patented AeroRotors with the best airflow available result in better cooling, less fade and longer rotor and pad life
  • The stiffest aftermarket calipers with patented bridge result in better clamping under hard braking and less pad taper
  • Track testing of new applications ensures optimum performance

    Kits usually require these minimum wheel diameters:
  • 328mm rotor (12.9 inches) - 17 inch wheel
  • 332mm rotor (13 inches) - 17 inch wheel
  • 355mm rotor (14 inches) - 18 inch wheel
  • 380mm rotor (15 inches) - 19 inch wheel

    Checking wheel fitment is the responsibility of the customer.

    Available in the following caliper options:
    ST-40 & ST-45 - 4 Piston Caliper for Front & Rear Kits
