Re:best clutch kit for thundercat
IMO you dont want a true 2" lift on a AC unless your willing to upgrade the axles on it.. MTI builds a nice 1.5" lift for them and with 30s that will put you around 17"/18" depends on the tires real height and shock spring settings.
clutch tuning is going to be up to tires size as much as what terrian your going to ride.
free and cheap is to re-clock the secondary spring to B-3/B-4 and lightin the rollers by drilling them out and adding a shim to the primary sleave to lower the over all gearing onit, lots can be done to it to tweek it to your style of riding.
