RTAB - Pro Street 70D
The Rear Trailing Arm Bushings (RTAB's) are a know problem when it comes to good handeling. The stock rubber bushings were just not designed for high loads without deflection. Couple that with the age and abuse we're putting them through and the deflection causes eratic handeling both on and off throttle, in and out of the corners, just unpredicatable grip and handeling all the way around. Replacing the RTAB's with a quality bushing that eliminates the deflection of stock rubber busihngs will make a dramatic difference in overall handeling making the car far more predictable and controllable, even for daily use.
General fitment and installation
The new bushings are designed to go directly into the stock location on the rear trailing arm and fit the factory mounting cup without any modifications. You will need to remove the arms from the car and remove the stock bushings to install the new bushings.
We call these our Pro Street RTAB's because they're a solid material but will outlast the Pro Comp Mono Balls for street use. The black Polyurethane bushings are the same hard material (70 Shore D) we use on the sub frame bushings, similar to Nylon or Delrin. The urethane still offers some vibration absorbtion compared to our mono ball versions, but you will definetly get an increase in road noise compared to stock rubber or our softer urethane versions.
While we call them a "Street" bushing, this is only due to the improved lifespan over mono balls. They are still going to transmit a lot more vibration into the chassis that was not found with the stock bushings. The increase of road noise will add fatigue and wear in to all components associated with their use.
