The Circuit Sports Extended Lower Ball Joints for the Mazda Miata NA/NB 1990-2005 are a direct replacement, bolt-on unit that will give you -2 more degrees of camber instantly and allow for a camber adjustment range somewhere roughly between -0.5 and -4 degrees. Over time, the dust boot on your OE ball joints can deteriorate, introducing dirt and other particulates into the joint. This can cause clunking, vibration, and/or excessive tire wear. Our lower ball joints are made with high quality components and are built and assembled by an ISO9001:2000 certified manufacturer: including forged housing/stud, high quality rubber boot, and oxidation/corrosion resistant silver zinc coating. Each unit is also built to tight tolerances, which allows for a 40% stiffer improvement of the ball stud joint over OE and allows for greater durability and longevity. Purchase includes high grade nuts and cotter pins for easy and direct installation. Professional wheel alignment highly recommended after install; we suggest extending the inner tie rods by a few mm on each side to compensate for the toe-in.

*Sold in pairs (Price is for two lower ball joints)
