This clutch kit is for the Audi S4/S6 with AAN 20vt motor with the stock flywheel.
Can also be used in any of these cars with an 01E transmission with the 01A style flywheel. Clutch level descriptions:
Stage 1: Stock-like daily drivability and very good wear characteristics. High clamp pressure plate, steel-backed and multi-compound woven organic material and high torque sprung hub and disc assembly. The perfect choice for a slight upgrade from stock type power levels, for example, just a chip modification.
Stage 3+: This is the ultimate High HP Street kit, offers good, stock-like daily drivability and better manageability than the stage 3, with even better wear characteristics. High clamp pressure plate, full-faced carbon metallic friction material, high torque sprung hub and disc assembly. We recommend this for street or track driven applications up to 550 crank HP, you simply will not wear this clutch out.
Please Note: This clutch is a non-stock item and availability is dependent on the manufacturer's current inventory. Allow up to 48 hours for processing when ordering, and please contact our Sales Staff for current availability if a rush order is needed.
Note about break-in: This clutch uses a heavy duty clutch disc that performs well in very high torque use that produce extreme shear forces and heat. In order to gain this performance advantage, the disc friction material is much harder and more robust than the typical OEM organic disc. In addition, the disc backing plate, what the friction material is riveted to, is much more rigid. OEM clutch discs use a type of belleville spring washer to allow the disc to compress and be compliant when being clamped between the pressure plate and flywheel friction surfaces. These high performance clutches, however, use a solid steel backing plate which does not compress at all, this type of construction gives the disc its incredible strength, but means that the disc will require more break-in time than the compliant OEM counterpart. Keep in mind that this clutch may have trouble fully disengaging the first time it's used, and will require much more break-in than the OEM clutch to achieve normal use. Typically up to 1000 miles of use is normal to get full break-in. Be sure break-in use consists of generous stop and go as well as shifting, the slipping action as the clutch is engaged is what facilitates the break-in process. Ultimately the break-in process is one that allows the clutch disc to conform to the pressure plate and flywheel friction surfaces, once these surfaces conform to each other they perform very well and offer the maximum clutch holding power possible. Be patient with initial use and driving and you'll be rewarded with an incredible performing clutch system!
