The GKTECH S/R chassis rear knuckle reinforcement plates have been designed to brace the OEM rear knuckles where it needs it. If you've been drifting these cars for a while now, you would have seen the OEM cast knuckles break off on the balljoint mount and the toe arm mount, usually happening in spectacular fashion. We've made reinforcement easier than ever with our laser cut, pre-folded, ready to weld in plates.

This is considered a must-do modification, as the OEM parts get older (more abused) and the difficulty of finding a replacement increases (and more expensive), we find it important to refresh and improve on OEM parts. Available separately for those who don't feel the need to reinforce all points.
