so i did some readin and people seem to favor the DMF over the SMF. Should i buy a new DMF and if som wheres the cheapest place to get it? thanks
Not sure what people that is what favours them things, but it isn't many. If you drive around empty and never tow and make sure that you only buy stock clutches, then a DMF will work OK, otherwise get rid of the thing, it's a ticking time bomb waiting to go off, even a new one is if you tow heavy.
Best setup is a 12 1/4" smf setup with that clutch you get about 9 springs in the center of the disc and basically zero rollover noise, with an 11" you only get 5 springs and you can get significant rollover noise. If you do get a DMF only use a stock replacement clutch, never a heavy duty, if you do, the overload protection section in the center of teh DMF becomes the weak link as it grabs less than the heavy duty clutch and once you slip that thing, the DMF is toast.
THe DMF is something that was designed to make a transmission quiet for folks not used to driving real vehicles. ZF used it on a number of different vehicles.The design works fine in BMWs for ultra smooth takeoffs and no jerking in traffic and cutting engine vibrations, but it pretty well sucks in these things. Nothing like hooking up to your trailer and going to leave out and hitting the throttle and watching yout RPms go up and not your speedo when you have a brand new clutch

Fort Wayne Clutch and get a rebuilt KEvlar lined 12 1/4" clutch kit, kevlar pilot bushing and solid flywheel and you will be in business . Another nice side effect with that setup is they are easy on the left knee. THe friction is so high with the kevlar that they don't have to use excessive clamping force which means easy work for your left leg and long lasting flywheel, and I regularly tow over 18k.
