79-85 Suspension bushings and links

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.

Strut top shims for 79-85
Part Number (each)	34-0130-1011
These factory shims are 5mm thick and are used to adjust the front ride height left to right. They are installed between the strut top and the strut tower to raise that corner of the car. We have found these useful after a minor fender bender. We have also found a few cars that had nothing wrong, they just didn't sit level. Maximum number per side is three.

79-85 Rear Lower 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.
