problem is that these are just about a millimeter shorter than stock, and after a while they will cause your clutch to go POOF.

These things are 2/3 the size of Hobbit stock springs and DIO springs. Maybe you have have G.I. Joe kung-fu grip, but i couldnt stretch even the lightest one onto the shoe. Good Luck if you do :)

Great for Stock or Small-Bore Kits

The metal ones hit about 150-200rpm above stock; it's a great replacement for stock springs. The green ones were hitting at about 1800rpm with Olympia stock shoes. Haven't tried blues yet, but I know they're the stiffest of the bunch.
Awesome for a minute
