Polyurethane bushings for VW Golf I / Scirocco I + II / Jetta I / outer front axle anti-roll bar bushing — TA Technix

The original bushing is made of rubber: it filters well, but deforms under load. When cornering or braking, the arm moves by a few millimetres and the wheel alignment changes during the manoeuvre - this is the vagueness between the steering wheel and the wheels.

Polyurethane deforms much less: the connection becomes precise and repeatable, and the car responds at the same point every time. In return, you get more road noise and vibrations in the cabin, especially when cold.
