Grannas Racing Ultimate IRS
FD3S RX-7 Anti-Roll Bar
This is a rear anti-roll bar (replaces the sway bar) for the FD3S Mazda RX7 chassis. This thing is BIG, heavy wall lightweight but strong chromoly tube that will not flex or twist! The biggest and baddest out there... 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 rear 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 brackets and heims to connect to the factory control arm mounting bolts.
If you are buying this for the OEM subframe choose the OEM subframe option and we will include some weld on supports. Fabrication is required if you are using a factory subframe.
If you are using the Grannas Ultimate IRS subframe we are now welding on the provisions to hold this anti-roll bar for all subframes. If you have one of the first twelve IRS subframes these tabs would not be on your subframe but we can provide the provisions for you to weld them on.
