Stop Tech Big Brake Kit (front) 332/32mm: Passat FWD

Stop Tech Big Brake Kit  (front) 332/32mm: Passat FWD

Item Number:



StopTech Audi B5 A4 Trophy Sport front Big Brake Kits include 2 piece floating directional 332mm x 32mm StopTech slotted or crossdrilled AeroRotors with 7075 T6 billet aluminum StopTech AeroHats, 4 piston StopTech STR-40 Trophy calipers, StopTech Stainless Steel front brake lines and StopTech Street Performance front brake pads.

StopTech Big Brake Kits improve aesthetics and exceed stock brake performance in three areas. First, larger rotors increase heat capacity. Second, improved brake cooling dissipates absorbed heat. Third, 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, also referred to as brake bias. Regardless of rotor diameter, brake pedal ratio, brake pad material, or number of pistons in your calipers, your maximum deceleration is limited every time by the tire to road interface. If the brake upgrade you select adds too much front brake torque (as many do), it will drastically shift the brake bias too far forward and reduce your car's ability to utilize the maximum traction of the tires at all four corners (even on ABS equipped cars), increasing stopping distances dramatically. 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.

 Advantages of StopTech Big Brake Kits over other brake upgrades:

  • StopTech offers the stiffest calipers available, their patented bridge results in better clamping under hard braking and less pad taper
  • StopTech's patented AeroRotors® offer the best airflow available, resulting in better cooling, less fade and longer rotor and pad life
  • StopTech Balanced Brake Upgrades™ with optimum brake bias offer the shortest stopping distance with the best pedal feel
  • StopTech Stainless Steel Brake Lines are resistant to expansion which offers better brake modulation and a firmer pedal
  • StopTech Brake pads are intended for high performance street driving as well as light duty track use.


StopTech STR-40 Trophy Sport 4 Piston Calipers

StopTech's STR-40 Trophy calipers are manufactured from fully forged aluminum for optimal strength and light weight. StopTechs patented, removable center bridge further resists yaw (flex) and allows pads to be changed without caliper removal. The StopTech Trophy forged caliper is the stiffest aftermarket caliper available, stiff calipers offer better performance with no vibration or noise, improved pedal feel and no radial pad taper. Forging also produces a beautifully finished, nonporous caliper, calipers that are cast can have major issues with porosity which can even cause calipers to leak. StopTech does all finish machining (such as piston bores sized correctly for the application), assembly, and test in California. The calipers are then anodized to resist discoloration under high heat. Dust boots are standard on StopTech Trophy Sport calipers to keep the pistons clear of contamination and extend the service life of the calipers.

 Advantages of StopTech's STR-40 Trophy 4 Piston Caliper:

  • Pistons sized to match brake kit to vehicle application
  • 100% leak down and pressure tested to 2,500 PSI
  • Differential piston sizes minimize pad taper
  • Uses standard FMSI D372 brake pad
  • Uses Silicone dust boots
  • Made of forged aluminum alloy
  • Weight: 7.05lb (3.2 kg) unloaded
  • Improved brake pedal feel and feedback


StopTech's Patented AeroRotors

StopTech AeroRotors® are cast with a proprietary high durability cast iron formula. To test rotor durability, StopTech rented the California Speedway and ran a heavily weighted down car with StopTech rotors on one side and a competitor's rotors on the other. In this test, StopTech rotors were approximately twice as durable as the competitor's rotors. StopTech has had several sets of rotors run entire 24 hour races on winning cars.

The ability to absorb and dissipate heat is essential to brake system performance. The patented StopTech AeroRotor® features uniquely designed curved vanes with innovations on leading and trailing edges to optimize airflow through the rotor. This improved directional design minimizes turbulence and flows more air than any rotor tested. The result is up to 80% better airflow over original equipment rotors and 10-30% better airflow than directional vaned racing rotors currently available.


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. Please remember to give us your car application at checkout so we can double check that you will receive the right set
