250 Uneven front camber on Megane 3 RS Cup (~0.6° split) — where to look?

Hi all,

Just had a full alignment done on my Megane 3 RS Cup (3-door D95, completely standard suspension) and the front camber has me puzzled. Hoping someone here has seen this before.



Front camber:
- Left: -0°40'
- Right: -1°17'

Both sides are inside Renault's tolerance (the sheet shows -0°22' to -1°22'), so individually they're "fine" — but that's a ~37' / ~0.6° side-to-side split, which feels like a lot.

Caster is asymmetric too:
- Left: 6°29'
- Right: 7°00'

And the wheelbase isn't symmetric either — the sheet shows:
- Left side: 2633mm
- Right side: 2637mm

Background:
- Bought used, no known accident history, no visible signs of impact.
- Suspension is 100% stock.
- The left front hub bearing was replaced fairly recently because of a humming noise — and I still get a hum from the front wheel area on long right-hand bends. So either the new bearing is also noisy or the bearing was never the real source.

Questions:
1. Has anyone had this kind of camber/caster split on a stock RS3?
2. Could the alignment issue be linked to the hum (irregular tyre wear), or is that a separate bearing thing?
3. What would you check / replace first?

Alignment screenshots attached. Any pointers appreciated — I'd like to sort this before I start looking at coilovers and track use.

Cheers
