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.
