Maruha's own design to solve the age old problem of bouncy rides after installing lowering springs. By adding a 20mm stroke to the top mount, the shocks can travel more and give the proper dampening support that was lost when lowered.
 
Pressure formed for strength and light weight. OEM bushings from the NB Miatas will fit this perfectly.
 
Price is per piece.
 
UPDATE: We have added the extra option to include 2 genuine Mazdaspeed rubber bushings per mount.
 
Installation note***
NA Miatas will require NB bushings and hardware to use this top mount
NB Miatas can reuse OEM spec bushings.
Can be used with aftermarket coilover systems without pillowball upper mounts (i.e. Tein Basic)
 
If your aftermarket coilovers (usually the rear) can fit the OEM NB top mount, then it will also fit these extended top mounts.
