Hey, Tombie, no not on a D4, though I wouldn't mind one on my driveway:).
The two Mack's that failed were only on the road a couple of weeks, when they were pulled over by Vic Rds for PBS checks. (Mass management, axle weights). The dealer had put on 35%, without realising that they already have a slight tint from factory.
The cops did say that when choosing a tint fitter, make sure you go with one that actually has said meter. Apparently not many do.
They do "allow" :angel: a couple of % either way. Not sure how official that is, that's just what I was told on the roadside.
