Anyone know what this means please, VW parts catalogue.

Hi All,

I'm after some brake caliper carrier bolts and have found what I need but there are 2 part numbers and one is in brackets, anyone know what this means and which I should get?

A quick Google suggests they are different sizes (length).

N91168901 appears to be M12 x 1.5 x 65mm

N91194501 appears to be M12 x 1.5 x 35mm

My guess is that one would be for ventilated discs, and the other for plain discs, maybe?

Seems to suggest that the N91168901 is W/O performance brakes (=without performance brakes), that is smaller or unventilated discs. Unless you can find out more, would it just be simple to order both and get them delivered in the same order?
