So this is a unique situation I'm sure!

I am running Mustang GT calipers with 300M rotors. The clearance is very tight at the control arm where the ball joint is. So tight that to make them fit, the control arms were beaten with a BFH crazy

Even so, the control arm grinds a groove into the back of the rotor.

It's about time for a brake job and I want to get the right spacing there. Any suggestions besides "trash it for a different brake kit"?

Relative to the centreline of the caliper (lengthwise, between the pads), is the rotor near the back (i.e. 'inboard') or is it fairly evenly centred. If it's 'inboard' (very possible given the description) then you can by a thin wheel spacer (3mm? 5mm?) and stick it behind the rotors and then use otherwise as is. Ideally you want the rotor to be fairly centred in the caliper. If it's already fairly centred, depending on the way the pad bracket/caliper mount is setup, if it mounts on outside (wheel side, not car side) of the knuckle then you could add a washer/spacer (3mm, for example) between the bracket and the knuckle and then add an equivalent spacer behind the rotor and it would shift everything out.

Hopefully that makes sense. I can try and draw some crude pictures later if not.

Thanks, Salomon!

What you described is just like I envisioned. I was hoping nobody would say that it's wrong or dangerous to do such a thing smile
I will take a peek at how it centers up and hopefully just the simple wheel spacer will take care of it.

No problem. I can't see any issue with this at all and I've seen it done before. Just make sure you are still getting adequate lugnut engagement with the spacer installed. Depending on what size you use I would imagine you may need longer wheel studs, but I doubt you would with only 3mm, just make sure to verify!
