Racing Beat Mazda Miata Sway Bar Brace Kit 1990-2005 (Except Mazdaspeed)

Developed to stiffen any 1990-2005 Miata chassis, this assembly proves most beneficial when using any relatively strong aftermarket sway bar, including Racing Beat’s tubular bar. This kit both effectively minimizes chassis flex that reduces sway bar performance and eliminates possible cracking of the sway bar chassis mounts that results from repeated hard cornering.

NOTE: This brace kit will fit all Miatas, but is intended primarily for 1990-1995 Miatas equipped with POWER STEERING. The routing of the power steering lines required that we modify the brace support bar to provide adequate clearance for these lines on this application.

Several years ago Racing Beat developed a Front Sway Bar Reinforcement Brace for the 1993 RX-7 that suffered this same problem. We found that we could adapt this part for the Miata by designing a brace that would: 1) Tie both left and right sway bar chassis mounts together, and 2) add additional support to the sway bar chassis mount. Using the mounting bolts and retaining nuts supplied in the kit, a support bar is placed into position and tightened against the frame rail. (The support bar is indicated by the BLUE arrow in the above photo.) At the same time as the retaining nuts are being tightened against the support block, the sway bar mounting bolt is actually being forced outward against the sway bar chassis mount. (The above photo shows a close-up of the support bar in position.) This support provides a very simple and extremely effective way to load the mount and eliminate potential cracking and minimize movement.

Manufactured from hollow-core 1019 steel and utilizing laser-cut end flanges, this brace is finished with a rust-proof powdercoat finish. Installation is accomplished by simply removing the sway bar mounting bolts and inserting the brace and support bar. Step-by-step instructions with fully detailed photos are included for easy installation.
