| Polyurethane Bushings | ||
| Polyurethane bushings are a considerable improvement 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 suspension begin to function. | ||

| Strut top shims for 79-85 | |
| Part Number (each) | 34-0130-1011 |
| These are just the factory part that is 5mm thick. They have four holes for the strut top studs, and a large hole to clear the center of the strut top. We have found these useful when we need to level the front ride height, usually after a minor bend. We have also found a few cars that had nothing wrong, they just didn't sit level. Maximum number per side is three. | |
| Strut Tower Braces for 79-85 RX-7 | |
| 14016 |  |
| This functional design ties the two strut towers together,and triangulates the engine bay by also going to the firewall. At the towers it uses the stock strut studs and nuts, then mounts between the hood latch and the firewall. Made of steel, welded, and powdercoated, it is an excellent method of increasing the chassis stiffness of your RX-7. | |
| 79-85 Rear Lower Suspension Links | |
 |
|
| These seem to take a real hammering by
tow trucks, bouncing off curbs, and generally hitting things with the rear end.
When they have a bend in them, aside from being unsafe, they change the rear
end alignment, and should be replaced. 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 recommended. In addition, as the rubber in these 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, especially on race cars! The other problem area, especially on race cars, is the watts link pivot bracket. The studs welded into the bracket have a tendancy to break off. We have developed a bracket that puts the studs in double shear and greatly reduces this type of failure. |
