Swanny will talk all about the Southbend clutches and many others will talk up the ACT clutches. I personally took Josh's advice and got the Southbend DXD and for the very little unabused miles that are on it I have no complaints. I wouldnt buy based on my statement but I would PM Josh and let him throw his sales pitch at you
They seem promising and I know a lot of people use them.
Of course there is always ACT wich has been around for years in DSM land but at the same time you seem to see problems with them. Maybe it is cause they sell so many.
Post your short and long term goals with the car and give us a little more info about the car.
