The GKTECH V2 S14/S15/R33/R34 subframe weld in reinforcement plates have been designed from a 3D scan with the addition of CMM data to help to reinforce your subframe where it needs it most. Laser cut, steel and dimple died for strength these plates make reinforcement of the rear subframe a heap easier than attempting to do it yourself. The V2 reinforces the area around the rear diff more and the overall fit is better than our previous V1. Vehicle Compatibility: - Nissan S14 240sx - Nissan S15 Silvia - Nissan R33 GTS-T Skyline - Nissan R34 GT-T Skyline NOTE: Can be used on HICAS subframes however the rear diff/toe arm mounts would be discarded.
