Its been talked about before, but has anyone come to a conclusion about cooling issues on 03 pro-x's with 1-1/2" tracks? Is this just a 600 problem or should something be done to the 700, 800s as well. Im installing a 1-1/2 on a 700 this fall and was wondering if more headaches come with the swap. Also is the hillcross 14" wide the best 1-1/2" out or is it better to get a doo track cheap off e-bay???? any clearance issues?
