Los Angeles (September 2008) – StopTech, a leading manufacturer, supplier and innovator of world class brake components and brake systems for production-based race cars and high performance vehicles on the street and track, today announced the release of three new Big Brake Kits (BBK) for the 2008 Subaru Impreza WRX STi.
StopTech’s BBKs provide shorter stopping distances, better brake modulation, firmer pedal feel and less brake fade resulting in stronger, more reliable performance. StopTech’s BBKs achieve this through larger rotors that increase heat capacity and dissipation coupled with stiffer calipers and stainless steel lines that reduce system compliance.
The Subaru Impreza WRX STi Big Brake Kits from StopTech come with a pair of slotted or drilled floating directional AeroRotors with billet aluminum AeroHat, billet aluminum mounting brackets with stainless steel hubs, DOT-compliant stainless steel braided Teflon brake lines, high performance street pads and forged, high performance, patented calipers. The rear kit (part # 83.842.002G.xx) features ST-22 two piston calipers and 345x28 rotors, while two front kits (part #83.842.4700.xx and 83.842.6700.xx) feature 355x32 rotors with a choice of either ST-40 four piston or ST-60 six piston calipers, respectively.  
The three new 2008 releases join three prior StopTech front BBKs for the 2004-07 Impreza WRX STi.  One kit (part # 83.838.6700.xx) features two ST-60 six piston calipers with 355x32 rotors, while the two other prior kits (part #83.838.4700.xx and 83.842.4600.xx) feature ST-40 four piston calipers with either 355x32 or 332x32 rotors, respectively. StopTech also offers a wide range of BBK options for the 2002-2008 Impreza WRX (non STi).
StopTech was the first to offer balanced brake upgrades for production cars and remains the worldwide leader with over 600 platform offerings that dramatically improve overall braking performance.  StopTech’s industry leading technologies and materials, from rock solid calipers to ingeniously efficient heat handling rotors, result in shorter stopping distances, better brake modulation, and less brake fade.
