79-85 Rear Suspension Links
We have found that the rear suspension on these cars needs to have soft rubber bushings in order to move properly. Replacing the bushings in these links with urethane or heim joints is not functional. In addition, as the rubber in these stock links ages, it becomes harder. If you are trying to make the car handle consistently, we recommend replacing all four links with new Mazda links.
The other problem area, especially on race cars, is the watts link pivot bracket. The studs welded into the bracket have a tendency to break off. We have developed a bracket that puts the studs in double shear and greatly reduces this type of failure.

Polyurethane Bushings
Polyurethane bushings are an improvemant up from original equipment rubber bushings due to their firmness. They do not require nearly as much compression, compared to stock bushings, before they let the actual suspension begin to function.

WHEEL STUDS for 79-85 (12A)
Wheel Stud These "screw-in" studs are 2 1/4" long, with approximately 1 3/4" available for wheel bolting, with the correct 12x1.50 thread. They are needed when using various after-market wheels, or replacing the stock lug nuts that have integral studs. We do not supply nuts to fit them, as there are far too many styles needed to fit all the different wheels.
