The Spec Stage II Clutch (http://www.specclutch.com) is a mild clutch upgrade that uses a segmented disc. The disc, made of Kevlar, is identical to the disc in the Southbend TZ. The pressure plate is rated at 478 ft-lbs. For comparison, the tried-and-true RPS Max pressure plate (with stock disc) is rated at 580 ft-lbs.

I chose the Spec II over the RPS Max and the Southbend clutches because I wanted a solid compromise clutch. I didn’t want to spend the 550 or more for the RPS Max, and I didn’t want a pucked disc because my VR-4 is not a dedicated drag car. The segmented disc, decent torque capability, and advertised stock-like feel were exactly what I wanted.

I’ve put about 7k on this clutch and am generally disappointed. It certainly holds all the power I’m making (which is, admittedly, not that much). However, it chatters considerably during engagement and the pedal feel is very poor. There is little perceptible change when the clutch begins to engage–quite the opposite of the positive engagement feel of the stock clutch. Starts from a stop are infuriating, as is clutching on normal upshifts during street driving. After over a year with this clutch, I still feel as if I’m fumbling with the engagement.

Next time out I’m going to use something with a full-faced disc and a high-clamp pressure plate.
