It's only happened recently as I'd have my wheels off regularly enough to have spotted it...no paint/marks on the inner tyre wall although I do use a special under car/arch pressure washer attachment...a mystery

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Weird one that has everyone stumped so far.
How can a stock Cayman R generate wheel arch paint scuffing like this. It's the front drivers side. All tests of clearances with wheels loaded/unloaded have shown all's spot on. Steering racks aligned...geos good...stock ride height, rims and tyres.

How much static clearance from the tyre to the mark?
Tyres flex much more than you probably think when leaning on them. I've had to cut an extra large chunk off a diffuser on a race car to create clearance from a tyre that appeared to have ample space. On something heavier like a cayman it could be even worse.
Tyre pressure change or change of useage?
All this assumes the tyre lines up with the mark.
Cheers,
Dunc.

There's alot of clearance there...you can get your hand in there at max steering lock with the wheels loaded or unloaded on ramp.
Our latest theory is it 'might' have been moved in the workshop (pushed to make space) when the hub was loose during suspension works. Especially as the control arms were off etc.
The scuff only goes through to the undercoat. If it had happened during driving I'd say it would have gone to metal very fast.

If it had happened whilst you were driving it, I'm pretty sure you'd have heard/felt it, so I'd go with "moved whilst the suspension was sub-optimally attached" theory.
This is a source reference. Confirm exact model applicability in the original material.
