This SPEC replacement clutch disc is a Stage 4 unsprung 4-puck unit intended for early Mazda Miata/MX-5 1.6L models from 1990–1993. Built as a direct replacement for the SZ364 application, the puck-style disc provides a firmer engagement and higher holding capacity suited to aggressive street or track use. It’s a specific fitment part for drivers seeking a higher-capacity disc than stock in the supported chassis.
