You willing to give more info on the soundproofing you made?

Just was going through the Exedy catalog and found something different that i havent seen with all my searching. Its a new clutch for 2012 which in a way combines both ultra fibre organic and metal facing. Has the springs and also cushions also and rated to 500 Hp. Showed my builder today and he gave it the thumbs up. However doesnt list MR2 but will see if it can be done given they have the same flywheel as the Hyper single



To me it looks it has the best part of both designs combined

Take a look at the carbonetics range.  I know for fact the twin plate is very nice and also quite streetable.  I have one in both my MR2 & EVO.  They also do a single plate.

That's interesting rob, I always imagined the heavy duty clutch to be a bitch to use haha.
Does it have a similar biting point?

Thanks guys.
 
How about noise on deceleration or neutral with the button clutch. I was told by Exedy its a hit or miss

I personally find that a twin plate clutch is more streetable than a cushion button clutch. It is only once you get into the severe end with triple and quad plate clutches that you have issues with shuddering and banging, and excessive pedal effort.
 
I will admit that exedy and xtreme are the more compliant models of button clutches, but have found them to be prone to shudder after a while, and a lot of the american stuff can be unbearable once fully bed in over a few thousand k's.
 
The take up on twin plates is good, it is very easy to modulate slipping the clutch, as you are progressively engaging two plates instead of one. That said, the downside of most twin plate clutches is the noise. Depending on the motor, how aggressively the car is cammed and the make of clutch, they can range from a quiet chatter, to a metallic orchestra.
 
Carbon twin plates on the other hand are exceptionally quiet, very easy to use, can handle the power well and have a very linear take up being a full face of carbon material (they don't have a metal core. I have installed and used a carbonetics twin plate in an evo, and it was brilliant (although the push/pull conversion had a very backyard feel to it.)
 
Abuse is the only thing that will kill a carbon clutch, and that is severe launching and clutch kicking. We had a customer break one of the plates in a ATS & across carbon twin plate and the car still drove, just a slight difficulty shifting gears at high rpm was a giveaway.
 
Another option is to see if Jim Berry race clutches can build you a unit to suit your needs. He can match up a kit to suit your needs and likes, be it organic, coppermix, button or otherwise, and is reasonably well priced.

Hmmm, maybe I'm confused again. I seem to remember briefly driving an R33 Skyline which had an extremely (almost unbearably) heavy and noisy clutch, and I thought it was a twin-plate of some sort. Maybe I'm wrong.
Oh well, all I can say is that my heavy duty button clutch feels good (almost like OEM), considering that it can handle a decent amount of torque.
I guess in my previous post I was sort of generalising a bit too much. There would be big differences between different brands and so on.
