Single disks can only hold so much on a 10.5 format, period. I can take a clutch rated to hold 600rwhp and put it in a Mustang with a curb weight of almost 4000lbs and 100 less rwhp and toast it in a few outings at the local drag strip.The day I need a twin disc is the day I do an auto swap.
Do u really think u NEED it? I mean most of the big dogs run clutch dynamics and it holds great. Its rated at a "conservative 625ft/lb tq"...For $1100....screw that. I'm pretty sure clutch dynamics disc is good for atleast 800ft/lb from a single disc. Not sure if their disc will fit a newer stang but they work on the 79-04.
Can I get a link to them, I have a old Spec stage 2+ I wore the disc out and might try that idea out on one of the other cars.I am using their disc with a spec stage 2 pressure plate. Mine has been able to handle my car. I will keep that in mind though, but if u do a search u are the only 1 I have heard bad about them. Hell he sent me a disc without payment. I sent him the MO a week later.
PM me what you want for it.If you are interested in their disc I have one brand new, just used for mock up but never was able to bolt it up with the pressure plate they sent.
