Use the 3 special shims to remove the pre-load from stock clutches on the workbench - then the installation of your twin-disk clutch will go much easier.
On high-clamping force modified clutches (like the ones we sell), use the special red-top bolts supplied to start your pressure plate on the flywheel, they will pull the pressure plate in far enough where you can get the regular bolts started.
The 6 Grade 10.5 metric bolts supplied are the finest and strongest available and will ensure proper torque and fitment.
