Need opinion on best aftermarket HD clutch and pressure plate for FD with moderate mods (14 psi) for mainly street and some track driving.

Also, does anyone know the parts number for the factory clutch disc originally used on the early FDs. It had really poor life expectancy and Mazda changed to a different part number sometime in late 93/early 94 that had a different friction material that lasted longer. I had mine replaced at the dealer (mistake) with their factory part about 30k miles ago and based on the fact it is just about worn out, they probably put on the earlier part number. TIA.
