Description
UMI’s bolt-in rear coilover kit allows full ride height, spring rate and damping adjustments, while trailing arm adjustment enables fine tuning of instant center. The reinforced upper mount is a direct bolt-in (requiring one additional hole to be drilled) and holds a true 2-1/2” racing coilover with double-shear mount. The FEA designed reinforced lower brackets bolt directly over the stock rear lower control arm mounts, utilizing the existing lower shock hole(s) (may requiring drilling of additional hole depending on factory configuration). The 2-hole trailing arm height adjustment enables fine tuning of instant center location for drag launch or auto-x/road race rear steer tuning. 100% designed, manufactured and raced out of Philipsburg, PA-USA and always US materials.
We recommend installing the brackets then measuring center to center at ride height to ensure accurate shock part numbers.
Note: Rear shocks may not clear all exhaust tail pipes.
