Description
These JHM Stage 3 (hybrid Ceramic/Metal Backed Organic) street performance clutches are from a result of actual on car testing and from pressure plate clamp load testing that JHM had performed on all the available pressure plates for the B6/B7 S4 and RS4. Most of the on car testing was to find the optimal materials for the most streetability while delivering the performance any Naturally Aspirated B7 RS4 could dish out. As for driveability the hybrid combination of materials has made the clutch hold better and handle higher heat as well while still being smooth enough for every day driving with a stock like pedal feel.
Clutch break in is important and must be done properly. For the Stage 3 clutches you need to drive as much city type driving as you can for the first 500 miles (each time you start from a stop or shift it aids in break in, Highway mileage does not count).
