The stock springs in those things are TOTAL shit. if you dont have performance blue or paz springs, try and get three springs from the stock two shoe clutches. they are MUCH better. Either way, turn them all the way in till the bottom of the screw is flush with the bottom of the shoe. then turn it out for 720 degrees for maximum performance.
Dont forget to tap the holes in the clutch or else you will never get your clutch off.
