Yes.

I just drilled a simple hole lined up with the valve stem when it's in the 3 o'clock position (aft).
Unibit works fine.
Can't remember how I located the right spot for the hole. There's a few ways to do it.
I mark the tire sidewall with yellow paint so when the stripe is down, the stem is lined up with the hole.
Some put in little doors and such, but I live with the 0.01 knot loss in favor of simplicity.
No specific photos, but here is a zoomed in that gives you the idea.
The only problem I see is locating the hole in the right place. would need to be done with the rear pan on, but no access as it's very tight in there. I guess a 1" hole would leave a little margin for error. Stem cap can be removed with a nut driver..
Setup a laser pointer to point at the valve stem with the pant off. Then put the pant on and mark the laser dot with a marker. Take the pant off and drill the hole. Works perfect every time. I used this method to locate all my mounting holes.
Question, do you leave the valve stem cap off all the time or do you remove it through the same hole every time?
Anyone created an air pressure access hole in the wheel pants? Where on the pant? and if so, what kind of extension tool do you use to get at the valve stem...photos? And how do you drill the fiberglass without making a mess? Thanks
I really like this tire inflation tool from Cleaveland:

You use the brakes??For the past 24-years, I just remove the front of the wheel pant when I need air. This allows for inspection of the brake pads.
