Id buy one right now, the pics on socalevo.net are GORGEOUS. Apparently its going to be a contender to the tilton though, so Im thinking 3k is probly going to be about right. Bit out of my price range.

You have to remember that a true carbon on carbon twin takes five layers of carbon versus the two layers (discs only) from the carbon/steel clutches. The carbon is not cheap stuff and makes up for about 75% of the cost of this clutch.

The cold coefficient of friction is still pretty high with our material. How do we know? We continue to perform clutch and material testing (more like play time) on a 9 second alcohol injected SB Camaro (Jim's car). We estimate the car is making about 600ftlbs of torque. To give you an idea, with a 240mm single disc carbon/carbon clutch installed on the Camaro we have no slippage with only 2200lbs of clamp load. This is basically the stock size and clamp load of an EVO. We tried using only 1650 lbs of clamp load and it slipped the length of the track. We were all laughing to see the clutch afterward because it was fine.

I spoke with ACT regarding this clutch when I was at PRI and it seems like a nice piece, but the lack of a ceremetallic disk right now is going to make it cost prohibitive for a lot of people who can sometimes barely afford a twin disc as it is.
I have run only Exedy ceremetallic twins in my personal car since the single disc ACT's stopped holding, but I imagine this clutch will work quite well. If anything, it sure looks cool. I think a ceremetallic option would definitely be a hot seller.

Food for thought.
