With stiffer components and patented heat management technology, all StopTech High Performance Brake Kits provide shorter stopping distances, better brake modulation, firmer pedal feel and less brake fade for stronger, more reliable performance on and off the track.

North America’s leading manufacturer and supplier of aftermarket brake and chassis components, has introduced front and rear StopTech® Big Brake Kits for the 2015 Subaru WRX with stiffer calipers, larger rotors, higher friction pads, stainless steel lines and application-specific mounting brackets and hardware. StopTech High Performance Big Brake Kits (BBK) offer significantly improved braking performance, feel and modulation over stock systems and are available in a variety of caliper color/rotor finish options.

In extensive track testing with professional drivers, the front-only and 4-wheel StopTech BBKs for the Subaru WRX ran significantly cooler than the stock components. Drivers experienced less fade, better pedal feel and easier modulation. They also noted improved handling and steering thanks to front brake components that weigh approximately 9 pounds less per corner than stock.

The FRONT StopTech Big Brake Kits for the 2015 Subaru WRX include a pair of drilled or slotted 355 x 32 mm StopTech 2-piece AeroRotors and four-piston StopTech ST-40 calipers, as well as mounting brackets, stainless steel lines and StopTech Street Performance brake pads.

The REAR StopTech Big Brake Kits for the 2015 Subaru WRX include a pair of drilled or slotted 345 x 28 mm StopTech 2-piece AeroRotors and two-piston StopTech ST-22 calipers, as well as mounting brackets, stainless steel lines and StopTech Street Performance brake pads.

StopTech Big Brake Kits Include

  • StopTech ST Calipers - stiffer, forged, differential-bore calipers with a patented bolt-in bridge that eases pad changes while increasing caliper stiffness
  • StopTech 2-piece AeroRotors - pre-assembled, directional iron rotor rings with patented AeroVane fin design and aluminum AeroHats for optimal cooling
  • StopTech Street Performance Brake Pads – Kevlar-like, para-aramid composite pads for aggressive street driving and occasional track day or autocross use
  • StopTech Stainless Steel Brake Lines - braided stainless steel shielded Teflon-like lines for less system compliance and greater durability
  • Mounting Brackets & Hardware – hard-anodized, billet aluminum mounting brackets with stainless steel studs and all of the necessary hardware for easy installation
  • The AP Racing designed Radi-CAL calipers are FORGED versus the major competitor's cast calipers. These FORGED calipers are 25% lighter and 20% stronger than cast calipers of the same size in the same performance category. The entire Radi-CAL system was created from the Radi-CAL system designed by AP Racing for Formula 1 and NASCAR.

Great value
Color: Light Champagne, Size: 6
My son loves this suit. He has worn it several times and he always mentions how comfortable it is. We don't use the tie but the other three pieces fit him well. When it first arrived it did have quite a few loose threads that had to be trimmed. Pretty much all the buttons and quite a few of the seams had several threads that needed to be trimmed. After that it appears to be good to go. None of the stitching continued to come undone. For the price this is a very good suit for kids.
