The wall thickness if 2.5 mm I am playing it safe but I do think you could go to 2mm with no problem.
You start out with an idea then when you get there you go I could have gone lighter but not to be.

Yes I looked at passing air for brakes I worked out the area of the holes that I could put in and they still only came out at about 31mm from memory as you can only get 4 holes in the outer tube near the disk.
The ball joint spigots steal the spot for 2 more

I have designed a brake duct that sits ontop of the steering arm an travels all the way around to the caliper it will pass more air almost like a spiral ramp it also fits very well in the space left

I did drill holes in the inner tube(look on the top pic last posted next to the left off lower ball joint spigot) and on the wheel bearing face 3 holes(6 in total) on the lower pic.
Air from the brake duct will pass throught the upright and out the outer face to curculate air to the back of the wheel bearing assembly.

Yes the alignment was tricky for the first caliper but the second was easy as I used the first to make the jig.
I made a plate that the upright bolted down onto through the wheel bearing bolt holes.
2 spacers came up off the plate the first bracket went on the 2 more spacers the thickness of the caliper ears then the other bracket then 2 bolts through everything into
the plate.

Yes Jac Mac it is from VT I used one STD and one abs as I will run the speedo of the abs or traction control if I wish.
