ANSCS1010 ANSWER-RC 3 SHOE CLUTCH SPRINGS - 1.0MM SILVER (3)

 A lighter spring allows the clutch to engange earlier with more progeression. A thicker spring allows the engine to rev higher prior to engagement of the shoe coming in with more bite and more aggression. If driving on a low grip surface it is generally considered best to run a lighter spring making the car easier to drive out the corners.
