Not gonna comment on that, otherwise we will completely hijack Kev's thread .... forever...
Kev, I know you might not want to hear this right now, but I would agree with your misses on this one.
I know you arent using a dashboard for weight purposes, but wont you have any structure there at all ?
this is what worries me:
I've driven a track car which was white inside with no dashboard and the gauges were just bolted on with their mounts.
What annoyed me was that as I was driving, I couldnt focus on the readings of the gauges.
You can only have a quick glance at them while you're driving, and if you cant concentrate on the readings, thats not very good.
Thing is that dials and gauges mounted on white backround will take some getting used to in order to make the readings out.
Same car, one year later, had an alloy dash made ( just a box type one from one end to the other ) with 3M carbon sticker on top of it, and he drilled out the holes and mounted the dials inside.
The dials were much easier to read and my mate (the owner of the BMW drift car) agreed that he was having trouble reading them before. Problem was the sun hitting the white backround that made the dials hard to read.
But, you can always leave it as it is and see if its comfortable for you before you make any changes
... and to make things clear, I didnt drive the car on the track and I wasnt drifting. I just went for a spin in it
