Assuming that a rear wing is not feasible for most people, it would seem that one should install the BMW Performance trunk lid spoiler as well as bolting down at least a 45-lb weight on the floor of the trunk.

Has anyone tried this?
If I recall correct, Robin borrowed that figure from Sport Auto Super Test and I believe that may be accurate. Trunk lid help a little but weight at the back certainly helps, the one time I had 2 adults at the back of the car I felt the car was so planted over 180-200 km/h speeds vs. just the driver. Adding weight on the trunk floor may be a practical idea as long as you can center and keep tight that weight. Or go kinky and buy the Moto GP wing
