[PJS50]

I am running the sintered iron McLeod disk on my BB Cobra and I wouldn't have it any other way... The smaller disc helps with the shifting of my TKO too..
I toasted a "dual friction" type of disc in the car early last summer and the sintered one shows no signs of giving up, even after a few trips to the dragstrip and a long day on the roadcourses this summer...
It does "chatter" a small amount during street driving, but ONLY when one "babies" the clutch pedal, but if you are a bit more agressive with the pedal, the chatter disappears and really is 100% a non-issue...
I have close to 600 flywheel HP and 650-ish flywheel torque under my SPF hood, and the sintered disc doesn't even know the difference...
Dual friction discs are always "weak" on one side... Don't forget that...
