I've been up close and personal with a lot of high end race cars and, to the best of my recollection, have never seen a painted radiator in one. The Audi R8 at Mid-Ohio back in 04 comes to mind. Audi has left no stone unturned in their LeMans program. If black was an advantage they would use it. And they don't. The R18 still doesn't use a black radiator. Maybe they haven't thought of doing the Coke can test?
