I need your advice on my choice for rear wheel and tire set up. I've a 392 IE that I plan to drag race on the 1/8 and the 1/4 mile tracks. What size wheel and what brand of tire and wheels would be best for this hp and 6 speed. I'm not opposed to buying a set just for racing use and switch back to stock for the street. Actually the car hasn't arrived but I should get it on 2/28. Would there be any reason for waiting for the car before I buy new wheels and tires?
