Why are Mercedes brake discs not handed, but have curved vanes and drill pattern?
Turbo Mini Forums

I get the feeling the MB guys have done more than a little testing, so they clearly determine it's not a massive problem, but since the early 00s to even today, they have used one part number for LH Front and RH front discs.

This clearly suggests that the benefit of curved vanes is actually not that important?

Thoughts?

I'd say most people do overstate it....lets face it, the minimal amount of cooling any air moving through it would actually achieve in the real world would be pretty small anyway compared to the amount of heat energy you'd be putting into them when braking hard.

A bit like farting on a red hot poker before the Spanish inquisition poked it in lol

But if it was my own car, I'd like them to be "right" if it was easily and cheaply doable.
If a bog standard daily driver type thing as presumably the Merc is...I really wouldnt care. As no doubt they've already been proven to work perfectly well.
