Polyurethane Bushings

Factory rubber bushings are designed for NVH (noise, vibration, harshness) comfort, which means they flex and deflect under load — allowing the suspension geometry to change unpredictably during hard cornering. Polyurethane bushings from Energy Suspension or Whiteline are 3-5x stiffer than rubber, keeping the suspension in its designed geometry under stress. The result is more precise turn-in, more consistent alignment, and more predictable handling at the limit. The trade-off is slightly more road noise and vibration — a trade every enthusiast gladly makes.
