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. We suggest extending the inner tie rods by a few mm on each side to compensate for the toe-in.

Circuit Sports new R Package tie rod ends for Mazda Miata NA/NB 1990-2005. The “R Package” geometry as found on the special performance-oriented 1993 LE and 1994-1997 R Package Miatas significantly reduces bump steer that commonly occurs on lowered cars.

Kit includes high grade nuts and cotter pins for easy and direct installation.

Professional wheel alignment highly recommended after install.

(Price is for two Tie rod ends and two lower ball joints)

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 and new RP tie rods ends 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.
