iam the most un-mustang-guy mustang owner you'll ever meet. I KNOW my car isnt that fast, it only runs mid to low 13s depending on how well i launch. One day i'll get it to run 12s all motor and i'll be happy. Like i said, i dont mind losing, just means your faster and motivates me to get faster.
And btw, i like 300zx's. They are like the underdog of the rwd nissans since the 350s came out. but they are kinda porky(like my car lol) 480+ should have you seeing 12s like its cool.
