Delrin or Poly bushings? Worth it?

I have found that to take the best advantage of the power and traction
combination available with quattro, earlier braking and a late apex
allow the best time through the corner.  This dictates a slightly
different line and it may not be the shortest, but it limits the
amount of understeer plow that occurs and allows more time at full
throttle.  I didn't discover this on my own, but I've compared it to
the "traditional line" and it's far quicker.  Just ask my 951-driving
friend who followed me in my 200 around Pueblo many times one day.
