Just went to Aerodyne in Mooresville and I can tell you first hand, both the GT4 front lip and rear spoiler I have installed on my car (Varis) impressed everyone working there.

Photos and videos coming soon.

man you guys are really upping the standard of E92 M3 tuning...

Nice! Look forward to it.

The angle of attack (tilt) of the wing is adjustable to create different levels of downforce, just like when an airplane takes off the nose points upwards.

The GT4/S wing has four settings. I am currently at 3 (4 being max). Not sure what angle of attack that translates to. You have a much bigger wing which means you won't need to have an aggressive angle. Otherwise you may start to lose grip at the front... unless you get a more aggressive splitter.

Plus, downforce always comes with drag, which affects your top speed.

How do you adjust the tilt?
