Hawtness. The "Rosso Corsa" red is just right.
One nitpick though: the tire rubber blends with the setting a little too much and makes it look as if the car is floating a little. Maybe some thin highlights on the rubber would help ground it. My professors absolutely drilled this into my head when I was in school.
Nice model and render! I agree about the tires- you may want to increase specularity just a tad, as real tires are not dead black, but actually have a bit of sheen. Also, if there is a fillet right at the edge of the tire, you can map it a different color, and treat only the fillet to a bit more sheen and/or a bit lighter- just to add the highlight that Pedro_Julio mentioned.
Also, and I may be wrong here if the headlight glazing is tinted, but you might want to increase the ray bounces in both realtime and on the render quality tabs. It seems that the headlight glazing is somewhat dark, or not transparent enough.
Hot red!
