15's is not bad at all. I drive this car EVERY day and this is my first muscle car so im kinda anxious to get her up to par with the other muscle cars in the car club. Im guessing im would probably run 17's also with my current setup. After seeing the numbers for my friends car, i dont even wanna go to the strip yet. I still got reseal the tranny. Some bumb nut "fixed" the leak it had, but found out he did a horrible job when it was time for an oil change. He used orange silicon to stop the leak...and what a MESSY and HORRIBLE job he did!
Hopefully i can drop into the mid 14's when im done with the engine. That's all im hoping for *crosses fingers*
EDIT: Thanks for the pic greg!
