Well, as has been pointed out, it could be an issue in areas where roads are
really bad.  Here in Sunny California, the roads are pretty good,
pothole-wise, but there are still plenty of cracks and bumps in some of the
roads, which can be felt more "accurately" once you have the delrins in.
Overall, though, bushings are not shock absorbing devices, and the end
resulting ride should be determined by shock and spring/tire tuning.

Busings will result in varied NVH (Noise, Vibration, and Harshness), but the
ride is really determined by your shock/spring combo, and also the tire
specifications such as side wall height which will greatly affect ride.  Mark
may want to expand on his experience with Delrin bushings and how they
affected his ride, but IME it was more harshness and not a ride issue.

As far as reliability, Delirn bushings are as good as it gets when it comes
to Audi control arm bushings.  I have used Delrin bushings in some race cars
for 4 seasons and counting, on the street I don't think they will ever need
replacing (specifically with 2Bennett bushins IME).  I'd like to hear
anyone's reliability experience with Delrin bushings that wasn't excellent.

HTH,
