Mark replies,
The skid plate is still using the same front attachment points, the
tranny has not been lowered as it is in 2WD conversions, and the skid
plate is still parallel to the ground. I don't see how this results in
much of a lowering of the skid plate. My Syncro is at Detlev's being
fitted with a stainless steel exhaust system so I can't measure it for
you at this time.

Mark replies,
This is one of the improvements of Detlev's conversion design. The
original Audi configuration has the fuel distributor on the left, above
the exhaust manifold. This is then a very hot and crowded area that
limits the air flow and when a hot engine is parked, the exhaust heat
rises to the fuel system. Detlev's design has the fuel distributor on
the RIGHT in a large open area that is not anywhere near the exhaust
manifold.
Sincerely,
Mark Drillock
