Identify the different diffuser
tunnels. The straight edge on the
main tunnels goes along the outside
of the car (red in picture to the left).
The shaped edge of the tunnels
point inward and accommodate the
exhaust system (blue in picture to
the left). Another way to
differentiate the tunnels is that the
passenger side tunnel has an
indented mounting area that
corresponds to a factory mounting
bracket.
In the photo to the right (viewed as if looking up from
the bottom of the car), note that the Front Entry
diffuser tunnels correspond with the angled cut of
the main diffuser tunnels. The edges are meant to be
parallel to each other allowing the lower control arms
of the car to cut between them without interference.
