Hey, I failed to realize you had a Mazdaspeed version... Nice calipers, my buddy had a protege Mazdaspeed version. That thing was a monster, with monstrous torque steer, but I think it had somewhere around 300hp at the wheels. I ran him with the bike. It's a fast car. He had a problem with oil going to the turbo, he even had an inline filter that would catch the oil, but it would fill up rather quickly. He sold it though, he said the car did not like it in town, and had alot of issues. It was a hell of a lot of fun to drive though, we would switch and he'd take the bike.
BTW, is that a complete Crome valve stem? Or metal of some kind, and is that typical of your valve stems, when you change your tires?
