90 - 05 Miata OEM Mazda Camber Adjusting bolts - NA89-28-66ZD

Fits all 90-05 Miata MX5

Get rid of that clunk caused by your old tired camber adjusting bolts!

Mazda has improved the bolt and washer design for the 1999 - 2005 NB and these can be upgraded to on the 1990 - 1997 models. These are the latest fine thread, double notch version. Factory torque spec is 69-83 ft/lbs.

If you have had any recent suspension work and picked up a single loud clunk under hard braking or turning, chances are your alignment bolts are worn out. Another clear symptom of slipping eccentrics is having your steering wheel centered when driving straight then being un-centered or shifting orientation after turning one way, then shifting back when you turn the other way. That is your camber (and toe) changing on one front wheel only from slipped alignment eccentrics. These new bolts properly torqued should fix the problem.

Ad is for one bolt, optional Plate and Nut for the other side.
For a full vehicle set change the quantity to 8.

For even more clamping ability use our Heavy Duty Eccentric Cam Bolts that have a thicker washer design allows a much greater clamping load. These are actually cheaper that the Mazda OEM ones.
