I've got a car with what I'm told is the "AZ Clutch" in it. This puppy is a lightswitch! I'm told that when it was first installed that it was nearly undriveable it was soo grabby. As it is right now it shudders th ewhole car even on upshifts once I'm moving. The woman won't drive the car - she refuses to deal with the clutch at all. It seems to get grabbier as it heats up too - in traffic that's stop and go it can be a real bear. Revving to 2K and slowly slipping it out helps but then it heats up and grabs harder

I'm actually worried about synchros in the trans. Car makes some interesting clicking sounds in 1st gear as I let off the gas or slowly step on it once the clutch has been released and I'm moving. I'm wondering if this is the flywheel but as a pretty new owner I'm not sure that this isn't "normal".
My hope is that this clutch will get better over time. Supposedly it's much better now than it was but I never saw it when it was "really bad". How many miles does it take to break in and what can I do to speed this process? Is the clicking normal? If not, what the heck is causing it? Clutch pressure feels decent but I think I feel a slight click through the pedal sometimes - overall no biggie. The clutch shows NO sign of slipping which is a good thing - I'm around 390RWHP and have seen 427ftlbs on the dyno too.
Clutch in my RX7 slips at high boost WOT and that just plain ruins your day! WOT runs in the Supra once moving are pretty solid with no shudder as I shift it hard through the gears
P.S. In reverse it does indeed sound like a tractor

1st can sound pretty bad moving it around in a parking lot between cars where you can hear it at really low clutch slipping speeds. Please tell me this will go away!
