Vorshlag Spherical Shock Mounts (NA/NB Miata - Coilover Applications)

New for 2017, Vorshlag Spherical Shock Mounts for the NA and NB Mazda Miata 

This item is for a pair of mounts. If you need mounts for both front and rear, please order two pairs.

The factory rubber rear upper shock mount for the MX5 chassis is a big rubber mount, They wear out over time, can dry crack, even come apart completely. When these mounts are new they have a lot of slop and "slow down" damper reactions to vertical inputs in the shocks. We can fix all of that.

Vorshlag has been making spherical shock mounts for years, for a variety of chassis: Corvette, BMW, BRZ/FRS and more. These mounts specifically for the the NA and NB Miata chassis are made in house here at Vorshlag and feature our oversized spherical bearing you'll find in our camber plates.  These shock mounts are big, beefy, and as strong as a tank.  Removing the stock rubber top mounts and replacing them with spherical top mounts will drastically  improve suspension articulation and movement.

UPPER STEM DIAMETER: These shock mounts are designed to work with virtually any rear shock that is made for the Miata. We use different upper and lower bushings (spool pieces) to adapt the big 19mm ID of our spherical bearing to the shaft sizes of the very top of the rear shock. YOU have to tell us how to build your shock mount assembly by picking the proper upper stem diameter of your rear shocks at the drop down menu below.

The part we need to know from you is the very top - which will have a 10mm/M10 threaded or a 12mm/M12 threaded upper shaft stem. Typically an OEM or non-adjustable shock has a 10mm shaft and an adjustable aftermarket shock has a 12mm shaft. The shock mount sits on the shoulder or step where it goes from the big diameter and necks down to the small upper stem diameter. See the images below for a better explanation. If you are unsure about shock shaft upper stem option to choose, please email or call us.


Radial Bearing Spring Perch: Vorshlag's shock mounts can be configured with a spring perch complete with radial bearings and all appropriate spools or spacers needed to match your suspension. Very similar to our camber plates, the spring perches help in eliminating spring bind.  Many people will try and use thin torrington bearings, but they are just not up to the task of street driving, never mind hard core track use.  Please make sure during check out, you note the size needed to match your springs! 60mm, 2.25", or 2.5".
