Clutch

When I got my 91 AWD it already had a CDFC installed(have the box and reciept). Anyway, this clutch is not good, fades after just a few races. My question is, how hard is it to install a clutch in my DSM, most likely a 2600# ACT? Ive heard it takes a bit of adjusting because the stock slave(?) cylinder can't handle the 2600. Also, does anyone have a lightweight flywheel? Does it really rev much faster?
Thanks

You shouldn't have any problems with the 2600. Don't get the 2600 unless you plan to make some big power like over 300.
