I have installed several clutches in Zuk's over the past few months. I installed a stock replacement clutch from Advanced Auto Parts ($125) and it worked fine with the 1.3, but after upgrading to the 1.6 16 valve I was able to smoke the clutch so bad that the vehicle would barely move. I upgraded to the Centerforce Dual-Friction and I am barely able to get is to slip on or off-road. It is not as on/off as I expected so it is very comfortable to use on the road, but it took a little bit of adjustments to get it that way. The last clutch I installed was in the SLEEPER Samurai Project and I can get the DAKIN Heavy Duty clutch to slip a little....alot more than the Centerforce, but it still is a good clutch that grabs well.......but in my Zuk I wil definately run a Centerforce.
