Maybe I'm getting confused, but back in the 70's (I think) didn't Mclaren have brake ducts which extended beyond the tyre in order to improve FW aero efficiency (or something like that).
To my knowledge, the team that took advantage of the possibility of extending the ducts to benefit improve FW efficiency was Toleman in the TG185, in... 1985 (duh!). Notice how they match the upper surface of the FW, effectively extending the plane.
Stricter rules limiting the size of the ducts were introduced for 1986, if I recall correctly.
PS: I hope people don't start to think I'm a pain in the a** by constantly bringing Tolemans and Benettons of the 80's to the discussions, but I believe they were some of the most inovative F1's ever (and that's how I became a fan).
