Drill and assorted bits
1. Make cardboard templates. Measure wheel to the cardboard with car on the ground to get the rough shape and then take down a half inch or so as it's not needed.
2. Cut the spat and underside panel from template. Cut the endplate but leave some additional material for final trimming
3. Line up the spat and drill alignment holes through it, and the front splitter, and bumper lip as you go.
4. Start with a couple of attachment points at the bottom and then move to the top so it's all held in place. (tape the top so it doesn't scratch the paint while working)
5. Drill the right rivnut size and install it.
6. Drill the right size for the bolt through the spat and then bolt it up.
7. Repeat up from bottom to top
8. Move on to the flat underside, use three M8 rivnuts at the front, middle and rear of the underside. Caution, be careful not to let the drill pull through and punch a hole in the upper side of the spoiler as it.. sucks arse.
9. Cut 90 deg angles from your carbon square tube.
10. Drill holes in the 90 angles
11. Mark where you want the endplate to attach and drill through with a 1/32th bit so you have room to do if you mess it up.
12. Drill out the size required for the low profile nuts+bolts and then install. Put the flat washer on the inside as it grabs well on the carbon tube surface.
