315x60x15's on my 64 Dart GT

Thanks for the response...I was thinking about -4 to -6...somewhere in that range. You confirmed what I have been considering.

I have been watching your threads, your car runs awesome! BTW, your pace in building your car has been incredible. Great work!

Thanks,

What are you running for suspension.

Cal tracks? go about -4
