Been using it since 8 miles on the odometer
So far we're still on the stock clutch over 285 WHP with the SC 30k miles later!
Not that bad...flat foot shift is worse IMO. 1st/2nd are actually rather easy on the clutch win non-R tires. With R-comps and slicks 2nd and 3rd are the worst for the trans, but the clutch is generally best the lower the gear.
