Prothane’s polyurethane is a firmer bushing than the O.E. rubber. This yields an increase the longevity of the bushing and the front end alignment. There is also a direct improvement in handling performance. Steering will become more precise and there will be less tendency for vehicle “wander” on the highway.
It must be noted that with a firmer bushing there will be a slight increase in NVH (noise, vibration and harshness).
Both the red and black urethane bushings are identical in formula. Historically, red is preferred for racing applications, since a flaw (or crack) in the urethane will be much more visible.
