This is a bolt-in rear anti-roll bar (replaces the sway bar) for the MKIV Supra (JZA80 - MKIV) chassis. This thing is BIG! The biggest and baddest out there... but also made from lightweight chromoly tube. This is an awesome addition to the Grannas Racing Ultimate IRS lineup. This anti-roll helps the car LEAVE straight and STAY straight going down the track. Just watch the videos of my car and other cars running this setup.
This bolt-in sway bar replacement will make the entire IRS suspension more rigid. Removing the play and twist from IRS suspension systems is key in making it work better. The bar is mounted with two large billet aluminum blocks, and the end links are secured with full billet arms. The bar kit also includes heims to connect to the factory lower control arm mounting tabs.
The bar uses all the factory mounting locations to the chassis and stock locations on the lower control arms. So, you technically could run this bar with stock arms, or with any stock replacement arms including ours!
