What's a Heim Joint?
Heim joints (hyme joints if you're from Australia like SuperPro) are also called control arm bearings or spherical bearing bushings. Regardless of what name they use, they all do the same thing for your MX5 or 124 by delivering ultimate cornering performance. Eschewing traditional bushing materials like rubber or polyurethane and using steel to create a rigid connection for your suspension allows SuperPro's heim joint bushings to deliver maximum cornering ability. Don't let the words "steel" and "rigid" scare you off, the smoothly articulating spherical bearing allows your suspension to retain a plush feeling ride while still delivering top tier cornering.
Turning Good Into Great
SuperPro's heim joint bushing skips soft materials like rubber or polyurethane and uses the rigidity of steel to create a metal spherical bearing that provides maximum precision for racecar level handling. These heim joints will transform the feel of your Fiat or Mazda with sharp and precise steering response by eliminating any deflection or binding. Integrated molded rubber seals provide long term and trouble free cornering performance by preventing dirt and debris from fouling the heim joint bearings on your MX5 or 124 Spider.
Lightning Quick Response
Eliminating any bushing slop or deflection with a heim joint upgrade will create a faster reacting car by decreasing the time it takes for the road forces to transfer between each suspension component. When your tire hits a bump with OEM bushings each impact needs to reach the compression limits of rubber before the force can be transferred to the next suspension part. Using steel heim joints in your control arms instantly transfers the forces of the road, transforming your MX5 or 124 into a scalpel for you to carve corners with.
Built to Outperform and Outlast
Cornering performance is in the soul of the MX5 and 124, which SuperPro's talented engineers strived to accentuate when they designed their heim joint bushings. Their in house manufacturing facilities ensure they are able to deliver high quality parts that upgrade the handling performance of your Miata or Fiat and the lifetime warranty even covers hard abuse on the track if you want to perform your own bushing durability test. A car that was built to harness the road like your Miata or Spider can be made into an even better corner carver when you replace the soft rubber bushings with SuperPro's heim joint bushing set and for those who are always seeking out that next step in performance we have you covered with Superpro's Front Lower Control Arm Bushing Kit.
