Unfortunately that only shows solid rears. 8.4mm


Vented fronts are 20.4mm

If you have access to the rotor, the minimum thickness should be stamped on it somewhere.

well, i don't want to take it away if it isn't under the minimun thickness and therefore no, i can't look if it's on the rotor

what is the part number of the rotor you have installed. Basically the stamp with min. thickness you can see on the rotor when you take the wheel off. But with a part number we probably can find the min. thickness also on the internet.

i guess it's 17.4 mm, at least that's what shows up in the part shops

34 21 6 864 903
