specialty clutch. i get honda clutch kits (clutch, pp, pilot bearing, and throw out bearing) with flywheel resurface for 110ish. never bought a miata clutch but id imagine they are cheap. ive never had a customer come back with a bad 1. ive never spend over 200 on any kit with them. also most all are on hand to just be swapped out. those are all prices with the cores mind you. ive never just bought 1 outright.
