I too think that 40 lbs isn't going to make or break a car. And I for sure as heck want those items on the list in the car.
I believe we're going to be racing at about 100 lbs heavier than an RX7. I don't think that is too bad from a power perspective as I think we'll have more peak power and area under the curve than those cars, but that remains to be seen.
But the weight on the stang is not good with respect to tire loading. We do not have nearly the balance of an RX7 but we're running the same size tire. My rough calculations show we'll be loading the front tires about 20-25% more than an RX7 thus ultimately we'll high a significantly higher load per square inch of tire.
A larger tire, like a 245, might help. But I just got off the phone with Rodney at App Tire and he says that size on a 7" wheel is problematic. He indicates they used to put them on the BMWs in ITS back in the day but the weird thing was they would not always seat properly on the wheel, sometimes they would seat off center and there was nothing that could be done to correct it. When that happened they were worse off than the 225s and had a wheel/tire that was basically unusable. He advised to not totally rule them out, but be forewarned if they don't mount properly there isn't anything that can be done. However, at only $8 a tire more than the 225s it might be worth looking into for the larger side to side and front to rear contact patch. I'd like to mount one up and chalk it at pressure and under load to measure the actual contact patch.
I asked him about 275s and he says they won't even mount those up for a customer. They're pinched too much on a 7" wheel and he claims the side width tire contact patch will be no better than a 225, although the front to rear contact patch might be larger than a 225. I told him Jeff Y has used them and liked them, but he wasn't sounding too convinced. So I suppose they're off the table for the stangs since they won't mount them anyhow.

Maybe my memory is failing me, but why can you remove the highlighted items?
D.3.e. Air conditioning systems may be removed in whole or in part.
In my shop manual there is a picture of the air conditioning system and it is the entire manifold, with blower fan, flapper valves, evaporator, etc. I can remove it entirely, or in part. I chose to remove the evaporator but the leave the plastic manifold and blower motor so I'd have some defrost action.
Wiper motors, I've still got mine but I think there is some language coming, or recently put in, that allows removal of wiper blades and systems, including the old faithful washer bottle. Mine is staying, both of them. The washer bottle weighs <1 lb and can become my catch can.
