I have about 20,000 miles on my Spec2+. Still chatters every now and then, much like the OEM one when it's damp, humid, or wet.
Still breaks the tires loose in 2nd gear when I want.
Back in May I stalled the engine on a hill, I pushed the clutch in stepped on the brake. when the engine fired I floored the gas before idle was reached, let the clutch out to slip while the rev's came up, car was moving forward a bit once I saw about 5000 rpm, I just dumped the clutch, the tires broke loose and I was on my way.
Stout clutch.
I do find in traffic it still tends to grab low, but I just put the tranny in "neutral" and side step the clutch at idle and it's fine for a while, depends on traffic.
Over all I still enjoy it, I wanted a clutch that would grab, I didn't want a noodle like the OEM clutch.
