Our FPSpec Extended Spherical Rear Tophats for the NA and NB Miata are featured on our Long Stroke FPSpec Ohlins kits, and allow for additional compression travel, while maintaining high durability. Teflon lined spherical upper mounts allow the DFV shock to operate properly as opposed to rubber bushings that defeat the DFV's ability to open and close properly as shock force builds when hitting bumps, berms, potholes, etc).
*These are compatible with Ohlins shocks, and may be compatible with other 10mm shock shafts. 12mm shock shaft bearing inserts are available on special request (please request 12mm shaft inserts in your order notes, default will be 10mm unless requested).
