Basically you've confirmed what I thought was the best decision..I'm gonna look into the Sport 500's..they seem like a perfect fit for what I want out of the car..I think SGP has them on sale also. Brad@ZSolutions, what kind of power are you making (approximate)? Z1 prices are fairly reasonable also. Thanks again everyone! I'll keep you all updated....I'd like to thank Dee (Slowninja) for all his advice as well...the money sure goes fast on a project like this! lol.. Rob
