The word was that the taller R&P�s were NLA pretty much. I don�t know about
the problems getting going. The TDI has serious low end torque. But the
brakes? I have G60s in the front and Audi 5000 turbo rear disks in the back
so I should be good.

The real answer is the 5 speed transmission but I don�t have the courage to
ask how much one of those is. Do they fit in syncros?
