The Karcepts SCCA C Street Spring Perch Conversion Kit adapts your 2016+ Mazda MX-5 Miata OEM springs to any 52mm Race Damper.
- 3D CNC machined to perfectly replicate the OEM spring seats
- 6061-T6 black anodized aluminum
- Will fit any race damper that measures 52mm in diameter across the threads
- Known fitment with JRZ, MCS, Moton, AST
To install: Flip the race damper's lower spring perch upside down to provide a flat surface to support the Karcepts lower spring perch. Simply slide the Karcepts perch over the 52mm damper body. Set the race damper coilover height to match that of the OEM assembly (to remain C Street legal). Replace the race damper's upper spring perch with the provided spacer/bump stop support. You cannot fit the race damper's upper spring perch within the OEM spring assembly, so this spacer takes up the void created from the removal of the upper spring perch (it also acts as a rigid surface for the bump stop). Complete install with the OEM spring, boot, top hat, and hardware
