The GKTECH solid subframe conversion bushings are a direct replacement of the standard items and allow you to fit an S14/S15 rear subframe in your S13/240sx, aswell as R33/R34 rear subframe in your R32. The solid bushings also ensure that movement of the subframe is kept to a minimum. They eliminate axle tramp whilst also raising the subframe which helps to correct the roll center on lowered vehicles. - CNC Machined from 6061-T6 aluminum Vehicle Compatibility: - Nissan 240sx - Nissan S13 Silvia - Nissan Skyline R32 GTS-T (2WD) - Nissan Cefiro A31
