[QUOTE="Jam421, post: 15546414, member: 110985"] Okay..........I'll bite on the McCleod user thing (:->) . Spec SS My stocker let go on a dyno in late 2014 after some mods . I got the car used and to be honest it became suspect shortly after purchase when stock with the 331's. At least it the car broke in a good place! If I flat bedded the broken car home (waited a week) the Kansas Ford dealership where I got the car offered to speak with a NY dealer for a 20% discount. Another flat bed. Nah....the shop installed the Spec SS which until that time..whether single or dual disc Spec was my absolute "go to" clutch. Pedal was a bit stiffer but I felt that was a trade-off for bite & hold which it did very well. Chatter at red lights was very noticeable and a bit annoying . Again ...I felt above certain power levels there's always comfort trade offs. I broke in the clutch carefully for 600 miles. After about 2200 miles with the Spec SS my buddy with a ZR1 wanted to go out to play . So that week perhaps 15X I start doing the hard 1-2.....roll 2-3-4 hard. TC OFF. The car was never at the track but this was to be on a country road ....so it was time to practice for sure. That next weekend we text...I roll away from Sunoco and hit it in 2nd at 25-30mph. Whip !!
