The Goodridge G-STOP clutch line kit for 1990–1993 Mazda Miata NA swaps the OE rubber hose for a PTFE inner hose sheathed in braided stainless steel with a Teflon coating to resist abrasion and corrosion. The lower-expansion PTFE hose reduces spongy pedal feel and improves clutch feedback for sharper shifts. The kit ships with conversion adapters and all fittings required for a straightforward replacement.
