For the 2000-2005 Mazda MX-5 Miata LS (NB), Whiteline makes the Front Upper Control Arm Bushing Kit. It goes on the front of the vehicle. In the box: 4 bushings and 4 tubes. Application note: Adds 0.5 degrees Camber: “”Approved for Spec Miata in both SCCA and NASA””. The part number is KCA452. Trim named on the listing: LS.
Most factory control arm bushings are centered and fixed. An offset one is built so the arm sits at a slightly different angle, which changes camber, and the firmer material stops that setting drifting under load.
Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. Working on the same car? We also list Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front Strut Tower Brace for the MX-5 Miata.
