It's so pretty though.
But honestly off track it can be used in noticeable ways, with the obvious areas being on ramps and such. At speeds that previously would begin to break the back loose now grip. Corners I regular use I've consistently increased speed on a regular basis with no loss of traction. I've had others who've driven the car before and after the wing was installed that attest to the same (and truly before and after wing installation as to not attribute feedback due to other mods).
