performance clutch springs
 

Now I know you can choose between 1000, 1500, 2000 rpm springs but what I don't understand is what that means...is that the rpm in which the clutch will engage? And if so then does that mean if I put in the 1000 rpm springs that my clutch is always engaged since it idles at 1700 rpms...and which would be better 1000, 1500, 2000?
