The OP is obviously talking about the latest trend in the quickest gassers, namely the "flip-up brake visor". It replaces the parachute. Pull a lever and the visor flips up creating an air dam to slow the car down. I think it's an idea that will catch on.
I haven't seen one. I was gonna joke... It's a downforce wing. Maybe not a joke. Sent from my VS835 using The H.A.M.B. mobile app
Sorry..No. Nor am I talking about using a sun visor or similar device to "block" or "blind" the first two yellows. See post # 33
