Clutch
Popular clutch upgrades. Power levels are estimated at the crank.
Stage 1 & 2 - K03
- OEM RS4 clutch disk & RS4 SAC pressure plate. Older but very popular setup on K04 cars.
- VAST stage 1 or stage 2 clutch kit
- Southbend stage 1 organic (est 350tq)
Stage 3 - K04/RS6/FT/Tial 605
- Southbend stage 2 organic/feramic (est 400tq). Very popular setup.
- Southbend stage 3 kevlar (est 525tq)
- VAST stage 3 organic/feramic disk (est 500hp/500tq)
- Clutchmasters FX400 6-puck
Stage 4 - Tial 770/GT/etc
- Vast stage 4 ceramic disk (est 540hp/540tq)
- Southbend stage 4/5 Extreme (est 600hp)
- Clutchmasters FX850 twin disk
- Will engage more abruptly and produce chatter
Pressure Plate
VAST, Southbend and most other single disk clutch kits use the OEM B5 RS4 pressure plate. An upgraded Sachs pressure plate is not a bad idea if you plan on lots of launching or more than 500tq. The Sachs pressure plate requires an extended throw out bearing[1]
Flywheel
Most people reuse the OEM dual mass flywheel. Your local NAPA or machine shop can resurface the flywheel, sometimes while you wait, for under $75. Use new bolts.
Lightweight, aluminum flywheel options
- AWE aluminum flywheel - 13.4lbs
- VAST aluminum flywheel - 17lbs
