P.S. Have you done any evaluation of a rear spoiler or wing, or is it too early to move to that spot?

Thanks!
I am definitley considering a wing. However wings, similar to canards and adjusting the front air dam, should be used to fine tune your aero system, and not be relied upon to provide significant downforce. It is somewhat similar to a sway bar being a fine tuning device after a complete suspension..you want to have the entire 'meat' of the system setup properly, then use the tuning tools to optimize front/back downforce balance. Contrary to popular thought, the large majority of downforce comes from underneath the car, from a properly designed underbody aero system. To put it into perspective- some ALMS/rolex cars can easily acheive 1000 lbs from their underbody system, whereas a normal 68" APR, BW or AM wing will only produce ~200-300lbs on a "normal" AoA...and even only 400lbs at their stall point.
Also- the problem with a wing is that in order for it to produce significant downforce, it will create a LARGE amount of drag. With a 335i on a road course, we do not have the power to balance out the additional drag induced by a wing.
So essentially, the wing/canards are the last thing you need, and only if you need to fine tune the system.
