That way the air can flow better through the vents of the disc. I know we are limited by the bulk of the spindle itself but it's probably worth trying to get the air as close as possible. Cool idea using the lower marker light as a vent.
Absolutely Nic! The outlet should end in the center of the rotor, NOT on the rotor braking surface. I think many has missed this important thing on
vented rotors, that the air is being sucked in at the center of the rotor on the back, and goes out thru the fins on the rotor. I´ve made a note about that in some other thread, that when upgrading to ´76 and later brakes on a ´75, dont forget to replace the dustshields too, because they have air-holes for the vented brakes!
The brakes on the pics I borrowed for the air-vent has much bigger rotors, so the outlet is actually quite OK.

Yes. I might do the S-10 swap. Have you seen my fellow swede grandam75:s observation that the S-10 spindle
mounted is actually longer, and not shorter than the original spindle?

Yes the stock spindle is about 1/4" taller than the S10 but if you measure the height with the ball joints attached you find that the S10 spindle with S10 ball joints is about 15mm, 1/2" taller. This should help camber gain.
Interesting!
