After 3 replacements of the clutch kit(every 10.000 km) +two of the flywheel i have this terrible loud noise every time i m in 1st gear.This started to happen after a day that someone else parked the car in a huge incline.I read lots of articles and i resumed that the noise is coming from the flywheel.My car is an R60 s All4.What flywheel do you recommend me to buy?Can i replace it with the flywheel of the JCW?Is another one stronger than that but in a reasonable price?By the way I m living in Europe(Greece)so it s not easy to bring it from usa.My last clutch (5000km)is a six wing metallic disc

 

If you are going through a clutch in 10k k. You need to learn a new technique for driving. ( I am not trying to put you down) I don't think any "better flywheel" will help. I recommend viewing YouTube or having another friend help you learn a better way to use the clutch. (In short you are slipping the clutch way to much when you are driving)
Just my opinion.
