I'm also wondering if the people that are having the problem are the ones that are pulling the trans and block together off of the bell bolts? and i never got an answer back on what they were setting the TQ to on the pressure plat to flywheel bolts as to why they are breaking and stretching?Quote:

Seemed way off to me too, but I usually like to listen to a manufacture as they made the parts, after trying what I was told, I went back to what I knew to be right, and torqued them 18 ft lbs.Quote:

I had higher hopes for this twin disc due to the collab w/ PTF, but these issues are far too similar to other problems Spec has on other platforms =(
Hopefully Motiv and Spec can get it worked out with the feedback and input from the early adopters.
Just got of the phone with SPEC and they corrected themselves and the NEW correct TQ Spec for the 6mm Allen bolt for the Super Twin-disc Prressure plate bolts is 10-12 ft Lbs
Sounds like they really have it together!Quote:

They are sending me out new bolts. Remeber to use RED thread lock guys!
when I installed mine, I used the higher TOB setting, had to draw the trans back on the last 1/2" with the trans bolts, was told by David at Spec to torque the pressure plate bolts to 12-15lbs*ft, have great pedal engagement height, ZERO issues with shifting, but have chatter/rattling under load while accelerating.
Anyone know what would cause chatter/rattling while accelerating? Is that normal for this setup?
I was not told to use ANY loctite. hmm.....Quote:

can i get your wheel specs lol never thought id see a set on a 335, been contemplating buying myself some
They told me to... I heard anytime you're screwing into aluminum you should use Loctite(thread lock).
Uhhh no. With the clutch engaged there should be no rattle. The rattle comes from the lightweight flywheel when the clutch is out...Quote:

Also clutch engages about 0.01 inches off the floor.
Thanks for everyones input. I guess it's better to learn from this then to not learn at all. Will report back with the new findings on the high setting.
Hope that works for you. I started with the high setting and it was the same as you describe.Quote:

That is so weird I thought PTF worked so closely with spec so we wouldn't have these issues ;)Quote:

Jake @ Motiv worked with Spec not PTF, Jake was at PTF before Motiv. (Someone correct me if I'm wrong)
I believe my Flywheel is Aluminum

I really don't know who or what company worked with spec but I know when I called them they said the clutch could only be purchased through PTF. I know both companies now sell them.
I was basically poking fun as I doubt spec needed PTF to help design the clutches. Spec said they were releasing the clutch long before PTF/Motiv got involved. Spec knows exactly what compounds need to go on their clutches etc. All I can think is they purchased the exclusive rights to sell it for X amount of time buy placing a stocking order of X number of units.
