I installed a 26 spline McLeod RXT in my son's 608 RWHP 03 Cobra. The clutch grabs at the top of the pedal and utilizes full pedal stroke to completely engage/disengage, leaving no room for TOB freeplay. Hill starts are terrible! Worst of all, between 1,400 to 1,750 RPM's in 3rd & 4th gear, the clutch resonates an intolerable noise, sounding like a loose exhaust. Two speed shops told me it was due to the lack of a Marcel on the clutch discs. Reinstalling the stock clutch eliminated the noise and proved their point. Tech support at McLeod is awful! Lee is the only one who knows what he's talking about, but he is seldom available and doesn't return phone calls, which leaves you to talk to the lead tech support guy who thinks "a 10 spline input shaft is all you should ever need". For me, McLeod is a one and done, and I'll be ordering a Centerforce DYAD which has dampening for both clutch discs.
