We have a spherical bearing set up on our shocks in all mounting
locations other than the bottom of the rear shock "Fork" mount. We did
this because of the precision that the bearing offers. Precise and
smooth operation that does not interfere with the shock function.
Spherical bearings are the best option for coil-over mounts. Rubber
mounts cause a "Trampoline" effect that must be overcome before the
shock can actually work. Rubber also changes the spring rate momentarily
until fully compressed. In addition, rubber causes side loads in the
shock rod and will eventually damage the shaft.
Plastic or Delrin eliminates the "rubber/trampoline" effect, but it
introduces new friction that interferes with the operation of the
shocks. Forces are forces and the friction involved in a Delrin/plastic
mounting system introduces "Hysteresis" losses that interfere with your
LG Motorsports famous GT2 coil overs, now for the C7 model Corvette including Grand Sport and Z06
*Models with Magnetic Ride will require shock simulators.
