There's a lot of information out there in regards to building Camaros, but there's not much correct, or helpful, information on body bushings. This is a perfect place to set the record straight.
To reduce road and drivetrain noise from transferring from the subframe to the body, Chevrolet uses rubber isolator bushings between the frame and body. As enthusiasts, we repair and/or rebuild our Camaros to meet the requirements for the way we plan to use or abuse our cars. Depending on our requirements, we need to choose the correct body bushings when replacing our old ones. There are three types of body bushings on the market today: rubber, polyurethane, and solid (aluminum).
ApplicationsRubber – These provide the best reduction in road noise and drivetrain vibration transferred to the body. Rubber bushings are the best choice for a completely stock Camaro and are perfect for people who drive rather cautiously.
Polyurethane – The next step up in performance is the semi-solid polyurethane body bushing. Road noise is increased slightly. These go well with hot rods without subframe connectors or with bolt-in subframe connectors. These are perfect for people who drive spiritedly on the street and occasionally get in some track time.
Solid – These bushings have no flex at all, which is a good thing when used in the right application. If you're using weld-in subframe connectors, solid bushings are a must. Welding a connector to a flexible frame (utilizing rubber or polyurethane bushings) will lead to frame cracking and damage. Solid bushings are perfect for people who regularly push up to and sometimes above the speed limit and race (drag, road course, autocross, etc.).
I have personally used rubber, polyurethane, and solid bushings on the street for many years. Solid bushings are not as harsh as one might think. Unless you wear a big hat while you're driving and have stuffed animals and a tissue box in your back window, you won't be able to tell the ride difference among rubber, polyurethane, and solid body bushings.
The majority of a harsh ride comes from low-profile tires and spring choice. If you have a Pro Touring Camaro, you're going to have somewhat of a harsh ride no matter what.
