ACT pressure plate weight
 
Anyone have an accurate weight for the Xtreme Pressure plate? And the 4 and 6 puck solid clutches?

I'm going to change mine and was looking at the Exedy twin disc (sprung) setup. I weighed the Exedy setup of flywheel, pp, and clutch plates at 30.4lbs.

The ACT prolite flywheel is 9.8lbs, but I can't find where I wrote down the clutch disk and pp weights. Anyone have that info handy or could weigh them?

Thanks,

Andy

I just weighed my slightly used ACT Extreme PP. It weights 12.2 lbs according to my bathroom scale.

I will be selling it shortly if anyone is interested in a slightly used ACT Extreme PP. :)

ACT 6 puck unsprung race disc, Part #6P240H (Turbo Applications), wouldn't even register on my bathroom scale, so I'm guessing under 2 pounds.

^most of the discs are very light. I tried to weigh my S/S disc and the other disc that was paired with the Extreme PP. Neither registered.

Thanks for trying! :-) However, at those low weights bathroom scales are pretty worthless. I did weigh the 4 puck solid and 6 puck solid a few years ago and they were both at least 2 pounds. I want to say 4 pounds, but that's pretty fuzzy memory.

In any case, the intent here was to go to the Exedy twin disk that alot of folks have had positive feedback on, but hopefully not gain any weight. However, using 9.8lbs + 12.2 + xx for the ACT setup means that total is about 25 lbs or so. The Exedy setup is 30.4lbs.

So I'm either going to find another setup or have a machinist take some weight out of the Exedy (looks like there are a few areas that could be worked on). That would require the assembly to be rebalanced of course.

interesting. Does the Exedy setup use the counterweight?
