  The six-speed gearbox has shorter 3rd, 4th and 5th gears, with 6th
  being same as the old 5th (0.73).  Hoppen Motorsport offers the
  conversion kit in the US, costing around $6000 for the parts.

  I have the Hoppen literature at home, and could send you the ratios,
  if you like.

  I've been told that 170 - 175 is about limit for the S4, because of
  gearing (our final drive is quite short, at 4.11.)

  I'd looked around for a 0.50 6th, which I wanted for those long
  highway trips, but couldn't find one.
