[Fot] TR4 Race Flywheel, Presure Plate and Disk Question

[Dan Cronin]

The alloy flywheels can be upgraded by having or installing ARP hardened steel inserts into the flywheel attaching holes which alieviates the tendancy for the holes to elongate.

Most folks seem to do a Fidanza aluminum flywheel.  Joe had a set of steel ones similar to what's sold by Cambridge made a while back, weighs the same and doesn't have the tendency to come loose from the crank like the alloy ones do.  Looks like this but for a TR4:

I use a diaphragm pressure plate like you describe with a heavy duty clutch disk.

The annular hydraulic throwout bearing is cool, but if you have any kind of failure you have to pull the tranny.  For that reason I converted from a very cool setup like that back to stock - so if the slave cylinder went out I had half a chance of fixing it at the track.
