I've got some C&C for you
+ The color scheme just
screams power sports, so stick to that!
- The header image is too busy. There are 4 images incorporated into one. You should try sticking to one, maybe two images and make a nice collage of those, or extract those from the original image to use them.
- The buttons are not too nice. They're too large, especially if you center the website like that. I'm only able to run at 1024x768 because I use a company laptop, which limits my viewing. But remember that I am not the only one with constraints!
- Buttons again. Get rid of them, is my opinion. Buttons are passé. They're like, sooooo 2005

If you get rid of them, try using text for linkage.
- The logo could use some more work.
- The blue text on a black background irritates after a few minutes.
