1) Remove grey plastic cover from trunk lid

Several things you will notice.
a) Instability over 85 MPH
b) Tail breaks quicker and easier in curves over 40 mph
c) Increase in 0-60 and 1/4 mile runs due to increased drag.

The Wing is functional not cosmetic, a team of nice Germans worked on 14 protoypes before they picked this one, trust their judgement...even if you think its ugly or ricer.
