['78 SC]

I firmed up the suspension of my '78 for track use: polybronze f/r, spherical trailing arm joints and Wevo engine/trans mounts.

I installed the front polybronze first and noticed no change in noise/harshness. There was a noticeable increase from installing the spherical joints. The engine/trans mounts increased cabin noise (especially higher frequencies).

I am decommissioning the car from track use and have swapped in softer inserts in the Wevo mounts. I intend to replace the spherical joints with stock units. I will keep the polybronze bushings front and rear.
