Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Bushing durometer (stiffness) has been carefully selected for specific uses:
Track/Race-only is for dedicated track cars that are never intended to be driven on the street (you might throw a plate on it and run to the store). Basically, if your car has racing harnesses instead of seat belts. These will be the stiffest urethane or Delrin for near-zero deflection and extremely precise alignment settings. NVH and comfort is not a factor in the engineering of these bushings. Our preference is for Delrin over Black urethane for track use.
Note: Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.
