I got a suter I have to say it took me half a track day to start getting the worth of one of these, it leaves you with less to do when firing down the gears to hairpins and slow corners, instead of slipping the clutch trying to get the rear under control while braking heavy, i found myself just counting each time you bang on the lever then letting the clutch out and the slipper would do the work, I look forward to playing with it my next track day, I seen bic and clinks post about the stronger spring and got one before I even tried it
