the buzzing on coast down is angular slop between the floater/pressure plate and the cover. When you are accelerating and letting the clutch out, the assembly winds up against one side of the "teeth" or "splines" in the clutch assembly and when you let off the gas, you're changing the loading against the clutch teeth/splines so that the variations in torque and vibrations cause them to rattle against the clutch cover. The stock clutch doesn't have a free floater or pressure plate. The PP is mounted solidly to the clutch cover and has nothing to rattle against.

i have one of these on the race car and find it awesome! has made my starts so much better and it is repeatable time and time again. who cares about a bit of noise! the weight of the unit makes gear changes almost instant! here is a start i like
Hung out to dry at the hairpin but **** happens. all cars infront were on slicks and in a different class. i was on r888's and got a class win. even if i was pushing way too hard trying to catch that evo.

Bringing this thread back for some feedback. It's 2017 now. I bet a lot of people who were running these back when they came out have some more experience/mileage. Can any of you chime in about how many miles you've gotten out of the clutch? Looking for organic.
Since 949 stopped selling the organic discs at one point and I didn't want to deal with the harsh ceramic stuff, I had to start sourcing replacement disks from ClutchNet - feel, longevity, etc. is just like the 949 ones.
949 just started selling new Carbon/Kevlar replacement disks - I am curious how do these compare to the organics regarding engagement and life.

949 doesn't sell organic anymore. The organic lasts me about 24 autocross events plus around 4000 street miles.

949 also sell single organic disc, stock diameter clutches which last way longer since obviously there is way more material on the larger diameter disc which should be a better fit for your street car

Since when do FM sell a twin disc clutch? And why asking about a 7" race clutch if not racing?

The reason you came to this forum is because it is the best info on the web for Miata stuff. That is because we police the content and posts. We can either sugar coat and give everyone a participation medal of life, or we can occasionally irk noobs that get lazy with the search function.
Welcome!
