F10 M5 19's Odd wheel damage :/

[Dez335]

Just after bit of advice the inside of the Alloys are scored around the inside. looks like stone between caliper and alloy?

its not all the way around though?? just two high spots?

Anyone have the same ??

Cheers Dez

This is on the extra set you bought, or on the existing wheels on the car? If the latter, there should be visible marks on the rotors or the brake shields

It could be a trapped stone, but not something I experienced on mine.

The only time I've read about something similar was when a calliper was wrongly re-fitted by a tech which caused major scoring on the inside of an F10 wheel.

I guess it's possible it was stones, but hard to say without understanding how bad the damage. If it's a few faint lines then stones seems viable - if deep scores then it sounds like metal on metal for a period of time.

I imagine the 19s are more susceptible to stones because they're tighter to the calliper - but if it was a big issue then the forums would be full of it.

Interestingly, there's a single M345 / 345M front wheel (which I think are the model of wheels you're considering) for sale on eBay that seems to be exhibiting the same damage you're describing? So maybe it IS a problem.

There isn’t much clearance between the callipers and the inside face of the 19’s and as I live down a 500m gravelled farm track I get this problem all the time - it’s sounds awful when it happens.

Extras i bought so not a big deal and will be used all winter.

I to live down a gravel track should be a fun clearing stones out.

Thursday is d-day!
