Hey Guys Chris(man) & I have been working on an AE86 RWD Corolla lately.
We do not have the Getrag on the 1UZ yet, but I will tell Chris to post on this thread.
Chris did get me a dual disc clutch from the same manufacture for the 1.6L corolla.
Someone had asked about this clutch on a W58 Trans, if all Toyota "W", & "R" series Trans are the same, the Corolla uses a W50 Trans, and they make discs for that.
In the corolla the clutch is very grabby. On/Off it doesn't want to slip.
The pedal is light. Not hard at all!! An old lady wouldn't complain about the pedal pressure. I actually thought it was lighter then the stock Toyota clutch.
Now it's a little bit more racy, but not undrivable. The Corolla is lighter, has much less torque, and has a 7.5-inch clutch Vs the 8.5 they are using on the 1UZ, but all those things should make for the 1UZ clutch to be a little more driveable. That and the Lexus has a 3.90:1 final gear, and the Getrag was originally mated up with a 3.13:1 final. Should make for some good burnouts.
The car gets a little jumpy with the grabby clutch from a stop, but other then that it's fine.
