I just bought an 03 F7 with a new one inch track with studs. I just picked up an arctic cat track I believe off a 05 F7 with 500 miles on it. It is like 1 3/8. How long of studs should I run with this. I don't want to mess up the heat exchangers. Is there as much tunnel clearance on the 03 as opposed to other years? Hopefully someone can help me out.
