Bmw m5 f10 disc

[Piston2022]

Hi all

Anyone has any suggestions on discs for m5 ?

My f10 has done 55k and rear disc thickness is 22.4 so worn out

Bmw stealership way too expensive as for read with pads it is £800 and front with pads £1400 so £2.2k

I understand rear minimum thickness needed is 22.6 mm and new it is 24mm

My disc thickness is 22.3 so Is it fair to say resurfacing won't help? If thickness is lower than manufacture spec then I guess disc ia not as strong as it is needed right?


Appreciate thoughts on pads and discs

yep both is worn I would say.

doing rear first as it is cheaper then front. You can't resurface them right?

Once it is below thickness of manufacture, what are the risks if you just change pads?

So called up costworld and they charge £1.8k with forum discount and checked online and getting it done at dealer it is £1.8k so buying it from dealer and get them to put it on is cheaper than buying the part alone!

Need to check front , rear is 22.3 but that is using varnier. Will test using micrometer. Pads at 4mm
