Grind the caliper down?

Every wheel will differ. So you have to make a choice,

If you can safely do it trim the caliper down if its that small and if its even safe to do so.

Ideal way is to get wheels that are a better fitment. You have to choose the best and safest route to go

I’m sure those brakes weren’t cheap, but neither are new wheels and tires. Do you run the 15’s for a particular tire, or really like those wheels?
I would agree that it looks like you only need half a scoche of clearance on that caliper. If you can confirm there is good metal thickness to safely remove a little. I would use a hand file, so you won’t remove too much too fast.

Do those calipers have bleeders on both sides? Hope you’re not using the bottom one to bleed it.

I would probably consider a different wheel option, maybe it would hit wheel weight if it had them on the inside

Maybe spacers?
I have the same STM front brake kit on my 1G. I have Rota Slipstream 15x7.5-40. With spacers, it doesn't rub at all. I have 15mm spacers and looks like I have 1/4"+ room between the rim and caliper. Without spacers, the clearance is too tight. It may clear but may touch the caliper, almost zero clearance.

These are the wheels that are commonly used for drag racing. I’ve talked to others thy have the same issue

I had 15mm spacers from JMF the wheel stuck out I too some pictures for reference for us to
Compare

i might just slightly shave off the caliper

I’m going to. Just a tiny bit

Is there still an interference with 15mm spacer? And yes, with 15mm would be like that, I happened to have a 15mm spacer, so I checked it with it. I think 5-10mm may clear the interference, too.

With the spacer there is not sign of interference.
I don’t like how much it sticks out. And with the spacer i have the issue with the hub rings i need them or the car will shake

Yeah would definitely need centric rings. I used the 15mm spacers when I still had stock style front springs. Good luck!

Thank you I’ll keep y’all updated once i finish the auto swap

A little update. I confirmed on my 1g that it would clear the caliper with a 5mm spacer. It would give a couple of millimeters room between the Rota Slipstream and the wilwood caliper.
