i have been spending a bit of time trying to make a carbon fibre tunnel cover and have got it done now.
i first bought a 1.2mm alloy sheet,did some drawings,some measuring and some more drawings, unitil i had the measurements i was happy with. i then drew lines on the inside with a marker pen where i wanted to fold the sheet. i then folded the alloy to give it a flat top as i dont like the rounded tunnel tops. i then measured the position of the gearstick and handbrake and began to cut the holes. once this was done i trial fitted it,and once happy i measured up for my carbon and a friend of mine made the c/f to my dimensions. i then stuck the carbon to the alloy with tigerseal and again cut out for the gearstick and handbrake. i then fit my chrome surrounds around the handbrake and gearstick and the end result is nice. i will finish the top edges with a radiused angle.
here is a few pics before and after the chrome surrounds!
