Cheers,

The gearbox and clutch kit are both toyota items, I have had my datsun flywheel machined and drilled to suit the (200mm) toyota setup.

I bought the standard AE86 kit because it was fairly cheap ($140 on my door), and I thought that at 200mm and about 30 percent more clamping area it should have been up to the task.

Your not wrong about the on/off nature of the puck/button setup, and with a slapper bar setup on the back end can be pretty nasty to reverse park, and take off from the lights (shudder, shudder, shudder, slap,slap,slap).

I`m trying to find a good ultra heavy duty pressure plate, I would have thought that the "haichiruko" squad would have plenty of off the self bits, but I can only find them in kits ($450+), ABS said they could get a (heaviest they make: 100 percent extra clamping load) pressure plate made up, but will take a couple of weeks and about ($220 on my door)this might be my only option.

If I get this new pressure plate I`d like to try the standard clutch plate again and use the puck/button plate as a last resort, My old setup in the wagon had a full face style clutch plate (180mm) and never slipped, so maybe a full face (200mm) unit will be upto the task?

It "only" takes a few hours to pull the motor and box, swap clutch kits and get it back in again, But I`m not as young as I once was, and I really know about it the following week.
