Hey,
The previous owner of my SW20 put a very savage clutch (feels like a button clutch) into the car and I was looking to put something more appropriate for street use in it.
I've thought about going back to stock, but I don't have the original so I was wondering if there were better options.
 
Cheers.

Greatly depends on engine torque/hp (aka what engine modifications) and driving style (street launching, hill climb/track days).
IMO get what the mechanic who installs it recommends and holds warranty. Use genuine Toyota throw out bearing.

Exedy HD.  Depending on your engine/gearbox, there's a couple of options...

Exedy has been great for me too. I've done multiple track days with no problems.

Cheers, I'll give them a look
