The front kit 83.119.6700.xx has the ST-60 six piston calipers with 355x32mm StopTech AeroRotors, while the smaller front kit 83.119.4600.xx has ST-40 four piston with 332x32mm AeroRotors
The calipers, AeroRotors, and AeroHats all hold patents for technologies geared towards shorter stopping distances, better brake modulation, firmer pedal feel and less brake fade resulting in stronger, more reliable performance on and off the track. StopTech BBKs comes 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 Audi A4 is a compact executive car produced by the German car manufacturer Audi AG since late 1994. The initial generation A4 succeeded the four previous generations of the Audi 80. And just like its Audi 80 predecessor, the Audi A4 automobile layout consists of a longitudinally orientated engine at the front, with transaxle-type transmissions mounted immediately to the rear of the engine, again, orientated longitudinally. Drive output is transmitted to either the front wheels, or, utilising Audi's 'trademark' Quattro permanent four-wheel drive system via a Torsen centre differential.
The new 2009 B8 Audi A4 and 2008-2009 Audi A5 brakes join prior StopTech front BBKs for the Audi A4 and S4. One kit (part # 83.130.6700.xx) features two ST-60 six piston calipers with 355x32 rotors, while the two other prior kits (part #83.130.4600.xx and 83.130.4700.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 2002-2007 Audi A4.
StopTech is the ultra-performance division of Centric Parts and was the first to offer balanced brake upgrades for production cars. The ten year old company remains the worldwide leader with more than 700 platform offerings to dramatically improve overall braking performance. StopTech’s industry leading technologies and materials, from rock-solid calipers to ingeniously efficient heat-handling rotors, have earned four patents that result in shorter stopping distances, better brake modulation, and less brake fade.
