Editing HICAS - Removal (section)

===Lockbars, why not?===
Lockbars are used for S13, R32/33 etc. why not for a HR31. For starters the system is completely different. The later model Nissans have a hicas rack (similar to a steering rack) that is attached to the subframe and pivots the rear wheels. This is replaced with a single lockbar, locking the wheels to the subframe, which is still bushed to the chassis. On a HR31, by replacing the rams with lockbars, you are locking the subframe to the chassis and eliminating ALL movement and compliance, and the subframe is not supported at the chassis pins as intended. The subframe is restrained laterally, but the sloppy up/down movement of the subframe with worn stock bushes remains. The result, all sideways rear suspension load is transferred to the actuator mounts, which will eventually lead to hammered out elongated bolt holes and distorted brackets, and you will then need to fit the bushes! do it once, do it right.
