Hello,
Nobody seems to be backing me up on this. Here's a link:

I cut my teeth on other types of vehicles before I got the cojones to work on 930 motors, so not all my input will be solely Porsche related. However, Torque is Torque.

Here's the deal. A lot of Bolts have a lot of tensile strength but are not that strong with relation to shear strength. Grade 8 bolts are very strong in relation to shear and tensile strength. You most likely can use any grade 8 bolt for your Pressure Plate. That's what I've used in the past for other clutches. Hope this helps. Your PP lies in between the Engine/Flywheel and the tranny. There is one hell of a lot of shear acting on those bolts.
