Damoegan - What's its like to drive for you. I have a pair of gauges in the same place and find it rather hard to see when turning right to the point of it being dangerous. Plan to move my when I can order a new A pillar from seat.
Guffers & RpR - No offence but that looks like a half done job. Now, if the vent still works the fair play, but just don't look right in my opinion.
I plan to fit 2-3 gauges in my air vents but I plan to block them up, get some ply/mdf/carbon/black matt plastic (not decided yet, lol) and do it that way.
The Prosport gauges do look the nuts. I currently got those Auto Gauges and I'm not keen on them at all. Boost gauge is starting to rattle.

. Don't know If the gauge is faulty or if I need to get that anti vibration t pipe, but I'm gonna get new gauges anyway. lol
