RRE's EVO X
Out in the shop we replace between 4 and 6 EVO clutches a week, for maybe 5 years now... we see what lasts and what does not. We have yet to see ANY Spendy Fashion clutch outlast an ACT clutch kit.
On cars making 400 ft lbs of torque regularly the sprung hub can become a weak point. The new ACT organic street disc with the unsprung hub fixes that problem. You just have to put up with the driveline gear backlash noise, the same as you would with a solid hub Spendy Fashion clutch. A Solid hub disc will get you louder more noticeable coast down gear slop noise (grrr-grrrr-grrr-grrr). There are drawbacks to removing the springs, and that is increased gear noise along with the potential for reduced hub spline life because of the lack of springs.
ACT’s new solid hub street discs are designed for the enthusiast looking for the lightest and fastest shifting possible with an ACT organic disc. Along with smooth and precise engagement like our conventional sprung hub organic discs, the new lighter solid hub versions offer less stress on synchronizers, steel backed linings for ultra high burst strength and race proven performance with street manageability.
