COMMENTS:

StopTech 83.100.4300.xx front Big Brake Kits for Audi MkI TT include 2 piece floating directional 328mm x 28mm StopTech slotted or crossdrilled AeroRotors with 7075 T6 billet aluminum StopTech AeroHats, 4 piston StopTech ST-40 calipers in black, red, silver, yellow, or blue, 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 Balanced Brake Upgrades™ optimize brake bias to
    offer the shortest stopping distance with the best pedal feel.
  • StopTech ST-40 brake calipers are the stiffest calipers available,
    resulting in better clamping under hard braking and less pad taper.
  • StopTech AeroRotors® offer the best airflow available which results
    in better cooling, less fade, longer rotor life and increased brake pad life.
  • StopTech Stainless Steel Brake Lines are DOT approved and resistant to
    expansion which offers better brake modulation and a firmer brake pedal.
  • StopTech Street Performance Brake pads combine the benefits of street brake
    pads with aggressive friction compound formulas suitable for increased temperatures.

StopTech ST-40 - 4 Piston Calipers

StopTech's ST-40 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 forged calipers have the lowest amount of flex and deflection among 25 of the leading caliper models (including some monoblocks) from well-known manufacturers. 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. Dust boots are standard on StopTech calipers to keep the pistons clear of contamination and extend the service life of the calipers.

 Advantages of StopTech's ST-40 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: 7.65 lb (3.47 kg) unloaded
  • Improved brake pedal feel and feedback

 


StopTech's Patented AeroRotors

The ability to absorb and dissipate heat is essential to brake system performance. The patented StopTech AeroRotor® assembly uses uniquely designed and patented AeroVanes® inside the disc to optimize airflow through the rotor. This improved directional design minimizes turbulence and flows up to 61 percent more air than any other rotor tested. The result is up to 80 percent better airflow over original equipment rotors and 10-30 percent better airflow than other directional vane racing rotors currently available. Better airflow equals better cooling, and better cooling means less fade and better overall brake system performance.

StopTech AeroRotors® feature a proprietary alloy chemistry. By adding molybdenum to the gray iron, carefully targeting a narrow range of hardness and tensile strength values, and controlling the cooling rate of the rotor after casting, StopTech produces a friction ring with added crack resistance as well as improved functionality. StopTech AeroRotors are 100% made in the USA.

 Advantages of StopTech AeroRotors:

 

  • Enhanced durability for decreased lifetime costs
  • Superior airflow for increased heat dissipation
  • Consistent and predictable performance
  • Less fade
  • Increased pad life
  • Extended rotor life

 


StopTech Brake Rotor Surface Finishes

Slotted rotors are preferred over drilled due to their larger pad contact area and their resistance to cracking, crossdrilled rotors are available for light duty or show usage. Zinc coating helps reduce surface rust on unswept portions of the rotor.

 Variations of StopTech AeroRotors:

 

 

  • Slotted
  • Drilled
