Factory rubber bushings were never meant to take much abuse and the sloppiness in your suspension can be considered a direct result. Prothane's urethane suspension bushings were developed to control torque and deflection, giving you a noticeable improvement in handling, cornering, and ride. Plus, they're unaffected by most chemicals and weather conditions, allowing them to last virtually forever. The Prothane Kit includes all of the bushings available for the AE86 other than the front upper strut mount.
Be advised, that this kit is best for those that are doing a mild (street sport) tune on their suspension. If you are serious about racing and plan to upgrade items such as your swaybars, 4-links, Lateral Rod, and TC Rods, most of these bushings will not be used. The first mistake I made when I purchased my AE86 was to go out and purchase the TRD Full bushing kit. I soon discovered that by the time I was done upgrading my car to my specific goals, only 2 of the bushings provided in the kit would be used.
If your factory bushings are worn out and if you want to restore your car to excellent sport handling and are doing mild mods such as sport lowering springs and high performance shocks only, this kit is an excellent choice!
