Trying to fit these Hope brakes that I got second hand from a friend, do I need an adaptor as the pads are against the rotors once fitted

That looks sketchy tight, it should be standardized spacing so it’s confusing that it’s an issue. Is there a chance your end caps are not the same and swapped? Is your through axle tightened normally?
looks good to me mate. if the pads rub when you spin the wheel then the holes are cut long so that you can adjust the position of the whole brake unit. Stick a couple layers of paper or a playing card either side of the rotor, between it and the pads (on both sides) after loosening the mounting bolts, then tighten down.
Just don’t adjust the calliper while the wheel is spinning or it might take your finger off (ask me how i know)
The spacing from the rotor to the caliper mount should be standard so that all brakes fit. The fact that these are so far off that you’ve run out of adjustment suggests that there’s another problem here.
Did the frame fit other calipers before these? Are you sure that the wheel is installed correctly, and that the hub end caps are in the right place? Is the rotor mounted tight to the hub face? It’s more likely that the wheel or isn’t in the right place than the caliper, but something is out of place here.
This will clearly need some finagling, you’ve likely got some stacked tolerances that don’t quite play ball.
On an IS frame you could face this to fit, but no dice here. I think the best option is to machine the hub down a fraction.
You could also add a 1/2mm spacer to the axle to move the caliper out, it’s also worth checking there’s nothing behind the rotor currently you could remove, and that you can’t adjust the hub on the axle (like how you would on a cup and cone hub)
