Delrin or Poly bushings? Worth it?

[TM]

It is really incorrect to imply that HPDEs run by other
organizations can't teach you how to drive your Audi quattro.

AWD doesn't make any difference when you're talking about learning
the proper line, how to apply brake and throttle smoothly, understanding
and seeing the apex of a corner, car control skills, learning about
under- and oversteer, how to heel-and-toe downshift and rev match
smoothly, etc. Those basic skills are all the same, regardless of the
car.

Heck, I practice apexing and proper exit lines every day in an
automatic Beetle. :-)
