I'm getting ready to replace the clutch, flywheel, and rear main seal on my vehicle. 00 v6 mustang. The stock clutch is so far at 132K miles and the clutch itself still grabs fine, and passes slip tests outline in the factory service manual. However, it's shuddering during take off from stop which is probably due to a glazed flywheel. Regardless, even if it's drivable now, it's a job that I can't put off for long because it will need to be replaced eventually and soon I won't have access to a garage (move to new apartment/city). Have you guys had positive/negative experiences with either Luk or Valeo clutches? Valeo is about 30% more but it might be the OEM. An online review of having to file an area of the pressure plate worries me about the Valeo. From pictures, the Luk has a 4-spring clutch disk while the Valeo uses 5 springs. The factory manual states the original clutch disk should have 5 springs - does it matter? Would the 5 springs dampen shifts better?
