Back in country and picking up where I left ofg on the spyder. Here's a link on previous post
http://www.dsmtuners.com/forums/drivetrain-tech/399828-clutch-will-not-disengage-engage.html

I'm going to replace entire clutch setup, but have a few blanks that need filling in...
First off, I am not sure still whays the problem, so i'm going to throw.$ at it 2 fix it

Secondly, I don't know what i'm missing on my list. Im leaning towards the act2600 extreme solid 6 puck kit. That includes act pressure plate clutch disc, tob, and allingment tool. Also going to add some motor and tranny mount inserts, shifter base bushings, found through STM - STM: 90-99 DSM DRIVETRAIN COMPONENTS -

I'm thinking oem master / slave cylinder replacments, as well as oem clutch pivot ball and release fork.

Might go through extrempsi.com since they price match and I have spent thousands there before.

Anyways, what am I missing or forgetting. Also, whats the difference between sprung and solid, 6 puck or 4 puck?

My power goals are mild @350-390 whp around the same on torque. I'd like to keep her as my dd, with light track and drag options. I live in the heart of atlanta, and traffic is thick. Dosen't bother my left leg a bit... But, I don't want to think about the drivetrain for another 50k. Looking to build best all around car with the dsm. Thanks and appologies in advance for grammer. i'm typing this my galaxy

any suggestions are appreciated. also, what and where can I find the gaskets and seals needed.
 
One suggestion I'd make is to buy an OEM mitsubishi throw out bearing and get rid of the ACT one. A sprung clutch is going to be a bit smoother engagement and a little kinder to the drivetrain, but there is a risk of a spring busting out. An unsprung disc is going to feel grabbier, but you don't have springs to bust out. As far as the 6 puck/4 puck goes, I personally don't know 100% sure the difference, so I'll let somebody else chime in on that.
 
What is the dfference betweena sprungand solid clutch? the difference between 4 puck and 6 puck clutches
Without getting into unnecessary detail: a sprung disc has springs in the centre section to help cushion the transition between "on" and "off". An unsprung or solid disc has no springs and thus there's much less cushioning at the transition between. Same idea for pucks. An "unpucked" disc would have a continuous circular friction surface and gives the smoothest transition between "on" and "off". On a pucked disc, instead of a continuous surface, you have the a number of separate friction surfaces (or pucks) separated by gaps where there is no friction surface at all. The idea is that all the power is being transferred over a smaller area and thus each puck (and all pucks combined)press harder into the pressure plate/flywheel. This explanation is an over simplification of actual but it's good enough to get a basic understanding.
