Ride

• Rubber arm bushings are far more shock absorbent than polyurethane bushings and transmit less vibration to your vehicle, giving you a smoother ride.
  
  

Control

• Because polyurethane bushings are very stiff, they give you pinpoint control of your vehicle, superior control to what rubber bushings provide.
  
  

Oversteer

• Polyurethane bushings can make your car oversteer at high speeds, which is when you turn the wheel and the tires, but your vehicle continues moving forward. This is dangerous, but race drivers, who prefer polyurethane bushings, know how to control and avoid oversteer.
