Darren can't you attach it to the LCR splitter? Maybe attach it to that seen as that one can come on and off with ease?
Not really mate theres not enough of the plastic splitter at the end's, Also to fit and remove the plastic splitter you have to bend it, if I attach the board tto it it wont bend.
What I was going to do was drill and drop a bolt down inside the 2 front supports, these will have to have spacers on them so they pull up tight, then drill 2 more bolt holes around the side's and bolt it the bottom of the bumper
I've decided not to carbon it for now, instead it will be filled and prayed gloss black.
The cost of the material's along are around £80 which is a lot concidering it might not even stay on the car, if all goes well and it does fit well and is useable then it will get wraped
I've cut a bit more out of the back of it today to give a bit more clearance to allow for the under tray to be removed easily.
Filler the grain with P38 filler and sprayed with filler primer, I've got Thrusday and Friday off this week so hopefully I should be able to get it finished and on for the AmD RR day.
