Thanks for the ideas, I will try adjusting them a little in post, I've never really messed with anything other than cropping and exposure adjustment so I'll give it a go. I do have some "better" pictures of it where the technical aspects are better (shutter speed, panning, motion blur, etc) this one was just the first one I noticed that highlighted the lack of detail in the wheels. It was way to hot to put a lot of effort into shooting this weekend, I have a couple shot at 1/2000 standing still on a tripod and the wheels always come out with the same effect.
