Yeah I've read they are starting to be a bit more leanient, after spotting people stopping on track and fitting camera's, which caused and accident.
I was thinking of using mine with suction mount, but will have to put it on the passenger window, its only a small suction mount so quite discrete.
Hows your Tegiwa "Racespec" shifter, saw your post in the Transmission section saying your punching the dash lol. I was thinking of getting one, as mine has a CMS 90mm extender, the throw is longer but with the Spoon gearknob im not hitting the dash, was thinking of adding a short shifter in maybe.
