Metallic rubing noise when turning right

Hello,
I'd like your opinion on a strange noise on my 1967 Elan S4 SE.
I have a metallic rubbing noise (difficult to describe in detail) which only happens when I turn right at a fairly steep angle.
As the speed increases, so does the volume of this noise.
The rear brake discs are new, the front discs are recent.
Do you know where it could be coming from?
Thanks

worn rear bearing or loose front bearing allowing disk to contact caliper ? or rear rim contact A frame bolts ?

I have had all the bearings checked and they seem to be fine.
The rear rim though is an issue.
I had the A frame grinded but it could be that there is still a clearance issue.
The noise seems to come more from vibrations in the floor panel, but it could be that the vibrations are spreading.
Hard to tell.

Could it come from a geometry issue? I don't understand why it happens only when turning right, and no issue at all when turning left...

If it’s a vibration could it be the exhaust catching somewhere as the engine moves on its mountings? Are the engine mountings good (not collapsed?)

This is a very good point. I have to double check that.

Check that the track rod ends aren’t rubbing on the discs when on lock.

That would be on the front. It’s something I noticed on my +2 The rod end cleared the disc in the straight ahead position but rubbed the disc on lock. This only happened on the LHS

Thanks Ian, How did you solve this?

I haven’t yet. The car is currently off the road. The rod end needs to be replaced as the rubber boot has perished. I just hope that the replacement has a bit more clearance.

Just a quick update on this question.
I have slightly bent (by hand) the protective plates from the brake discs to give more clearance. After a quick test due to lack of time, the problem no longer appears. It could be that the plates were too close to the discs and were rubbing during right-hand turns.
I also noticed that a stabiliser bar silent block is completely destroyed.
I'm going to replace it
Thanks again for your help.
