Min thickness of front & rear rotors for E82 135i?

[dojk]

Hi,

Would like to know what is the min thickness (mm) for the front and rear rotors for the E82 135i.

I don't' have the facilities remove the wheels to check the printing on the hats.

Thanks.

Front disc min thickness: 24.4 mm

Rear disc min thickness: 324mm dia - 20.4mm or 300mm dia - 18.4

The min thickness for the rotors is stamped right on the hub section of the rotors. FYI

I know, just couldn't be bothered to remove the wheel to see it.

Also because then I'll have to make a 30min drive to the workshop to retorque back the wheel lugs.

Totally laziness on my part.

Bollocks, my fronts are on 23.3mm. BMW's service center's goons had a look the other day, commented it's still good for another 6mths.

I'm sure they are safe to drive one for another 6 months if you wanted to. But they may warp if you are getting a ton of heat into them. If I were talking to you as a service professional I would say to replace them, if it were my car (DD not a race car) and I wanted to wait a bit I would probably roll the dice.

Thanks for this!
Probably doing rear pads this weekend (2mm left, according to a shop.)
Need to check on replacing rotors.

Just did rear pads.
Rear rotors are at 22.5mm, so I'm just gonna bed em in and call it good.
