So I'm looking to get a new clutch for the dune buggy. It has the small transmission (pre-67), and a 1600 dual port engine with stinger exhaust (a little more torque than stock exhaust). cable actuated clutch. currently slipping in 4th and a little in 3rd, so i'm thinking it's shot, and if i'm gonna yank the engine off to replace it anyway, i might as well upgrade to something that grips better, and will last longer. Basically wondering should I go stage 1, 2, 3, or 4. http://specclutch.com/products Thinking higher is better, but i'm concerned that they mght get more difficult to control @ the friction point. Is this a valid concern? How much of an issue is this?
