Makes me laugh to see all the people saying they're too expensive all drive Hondas. If you're build a real race car stuff like this becomes a normal expense. Look a set of Penske's, expensive for most club racers and even those are $7k and up. If you want to really race and not just drive your street car and act like a racer shit gets expensive very quick. No one who makes stuff like this ever intends for it to be on anything short of a high end race car.
