For sale is a 949 ceramic metallic twin disc clutch. I bought it lightly used and put about 500 street miles and one track day on it with my 300hp turbo setup. It could probably use a fresh pilot bearing, but is otherwise in good condition. It's a killer mod for the track, but I ultimately decided to go with a slightly easier to handle setup and sacrifice the performance since I still drive my car on the street. And yes, I turned in my man card to the proper authorities.

Free bump.

Just stopping in to make potential buyers aware that the difficulty of driving this clutch on the street is entirely subjective.

When I installed my ceramic twin about 6 months ago I was a bit nervous that it would be terrible to drive on the street. To my surprise, it's not difficult at all (for me at least). After a couple days of getting used to it, I don't even think about it anymore. It kinda shudders in 1st gear getting started from a stop, but after that it's super easy to drive IMO. On track, it makes shifting a lot faster and rev matching easy. Probably my favorite mod to my car so far.

 

+1, I just put mine back in a car last week and it's not nearly as fussy on the street as I recall it being.

 

LOL! Thanks for the help guys - I guess it looks like I'm trying to convince people not to buy the thing I'm trying to sell!

To clarify, this clutch is awesome at the track. The revs are insanely quick and shifts are faster and easier. Heel-toeing becomes very easy, forgiving and darn near optional - if your foot doesn't make it over to the throttle the way you intended it really doesn't upset the car very much. I even tried downshifting a couple times in the braking zone without touching the throttle just to see what it would be like - the passenger in my car didn't even notice. I wouldn't recommend making that a habit, but it's nice to know you've got a big margin for error.

If my car were track-only, I'd still be using this without a doubt. However, I still drive the car on the street. It's not a daily, but I will take it for a spin for a street shakedown after maintenance or upgrades, or sometimes if it's a nice day and I need a Miata fix. I think everyone is aware that with the narrow engagement point and very low weight that this is easier to stall from a standing start. I was able to adjust to it, I could start it without stalling, even loaded it on a trailer. However, I just never got to the point where it seemed "effortless" like it does for me with a slightly heavier flywheel and organic clutch. For me, it required more concentration than I cared to deal with for driving on the street, especially in the traffic that I sometimes encounter in the Chicago area. Personally, I'm okay sacrificing that particular performance at the track in order to have smooth, effortless starts on the street, but I know this forum is full of drivers (like the two above) who don't find it to be an issue.

 

SOLD!
