Another way to think about this is that the brake disc does not 'scoop' air from the perimeter and 'pump' it to the inside. There's a problem with centrifugal force in this mental model.
However, if we reverse the mental mode, and pump air from the inner perimeter to the outside perimeter we get helpful Venturi effect that 'vacuums' air at the outer perimeter and centrifugal force helps move air from the inner to out perimeter.
Unless you have the drilled rear rotors that only come in one direction <sigh>
Rear rotors typically have ‘straight’ guts not ‘spiral’ guts and thus are non-directional. There is still cooling effect from rotation, just not as much.
It could be worse: Your front rotors could have spiral guts but be only available in Left or Right thus cooling one side and not the other. See Audi... and the MkII TT-RS specifically.
In any case I think you’ve got bigger problems. Is the Cookie Monster eating your adjuster nuts and collars or just your photo’s pixels:
^^^^ Hi Dave - I just went and looked, all is good in the hood--just low resolution picture. But thanks for having my six
And now for something completely different. Thank you Porsche engineer that decided to have the actuating lever screw thread from the other side of the console. Looking forward to removing the center console just to get to that screw.
Yup.
These were done back in 2004, still look pretty good. This was a couple months ago after my once a year wheel well detail. Once you do it, pretty easy to spruce up every once and a while.

so is the ‘Porsche’ lettering on your calipers the raw metal or is that decal? Looks great

I took another look at it and now I see that it's the RDK sensor occluding the collar. Damn bits.

tool for the center console, unless you've already had it out once before and didn't put THE BOLT back in. Yes, the tool is expensive. If you've never taken an airbag-car console out before, if you don't get this in advance, you'll be paying for overnight shipping when you get to THE BOLT.
Obligatory 928 picture. Center console? What center console?
928 sighting on "Chasing Classic Cars" from July, but first seen by me tonight. This dark grey OB ('83? No rub strips! No sunroof?) was parked at Palumbo's Automotive in Guildford CT. The show featured a a Nash Healey that Wayne bought from the shop.
