For my last clutch kit, it was a Southbend stage 1 kit and of course the garbage Exedy disc exploded (typical spring retainers cracked). I simply replaced the disc with an OEM Aisin one directly from the dealership. Part number 31250-20140-84 - $62. So far, this $62 Aisin OEM clutch disc has been putting up with a 2GR-FE for 10k km's and 6 track days. It is likely the clamping force of the Southbend pressure plate that is doing most of the work, but I was not expecting it to have zero issues. It just shows you how the original Aisin spec is overkill already for the car.
Pros: durable, zero issues, good value
Vehicle:
Toyota MR2
Mileage: 10000 km
