Opinions are all over the place and feelings are almost as strong as in the great oil debates!!:biggrinbounce:I'm lost here. Somebody votes for UUC and others are against it. Rogue is seems to be OK but I don't know.
I'm going to replace my clutch but I need your help in deciding which one to take.
Packard had a great quote for their advertising - "Ask the man who owns one." In your case, Dave is that man. He has two M5s, one at each end of the spectrum - a stocker and an Area 51 monster. You would do well to follow his advice. It all depends on what you plan on doing with your car. If you're just going to drive it, by all means go OEM. If you are going to be racing it, something along the lines of what M5 Deamon has could fill the bill.I have both OEM and UUC equipped cars. For Diablo, no question... UUC. It is a great clutch and a joy to use in combination with a LWFW. Capable of handling a lot of power. When time to replace Diablo's clutch, it will be another UUC. However, for the stock beast, I'll stick with OEM. It has functioned fine for 66k mi. No complaints.
Hope this helps.
I am beginning to think that a lot of people, including me, may have been confused, or at least incorrectly just assumed, the slipping feeling is primarily due to clutch wear when it could also be the "SAC" mechanism of the stock LUK pressure plate at work that is causing the minor slippage feeling (as opposed to major slippage due to a worn clutch). Clutch may still be good & not even need to be replaced.I have to thank everyone for sharing their thoughts. My car is stock. The problem I have is when I drag race the clutch get hot I think and start slipping.
I am also interested in any feedback from rogue clutch (& flywheel) users. Sounds fairly good. Anybody?In theory, the SAC pressure plate is a noble idea for those that do not have experience driving a manual transmission. The mechanism tries to maintain the same clutch pedal engagement height at all times while compensating for clutch disc wear. For those that have manual transmission experience, it causes frustration as it compromises true clutch engagement and feel. Another downside of the SAC system is that it does not allow for full clamping force especially when the disc starts to wear from stock thickness. The Rogue Engineering PCS eliminates the use of the SAC pressure plate and uses a more traditional style pressure plate allowing the clutch system that allows for 100% clutch engagement that can be modulated.http://www.rogueengineering.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=RE&Category_Code=LTWF
Great write-up. I opted for the UUC 8 puck segmented kevlar clutch and LWFW due to hp limitations on the organic clutches. Three trips to the drags and the original S3 clutch was toast.I havee UUC Stage III, 6 puck organic clutch and LWFW. Some chatter on engagement, and rollover noise from the tranny, but I can beat the snot out of it and it doesn't even whimper.
I like to bang second real hard. I probably am breaking the rear diff mount a little, nothing some MIG welding won't fix.
However--this clutch aint for the faint of heart. You have to value performance first. Cost about $3500 installed. Last clutch I will ever buy for this car.
