Solid differential mounts for the S14 200sx and Silvia, S15 Silvia, R33 GTS-T, R34 GTT and R32/R33 GTR differentials fitted to the previous models. These bushes mount the differential completely solid and they will contribute heavily towards elimination of all axle tramp, and allow a much more solid feel when clutch kicking. By using solid bushes, more transmission noise will be transmitted through to the cabin, but no more than the solidly mounted diff in standard older Nissans.
