What is the big advantage over 5 lug to 4 (if any). Is it really worth it? I was thinking on doning a 5 lug rear disc swap. Is the stopping power that much better with 4 wheel disc? I have seen kits for the 4 lug drum/disc set up that is supposed to improve stopping power over stock (better pads, brake hoses, ect...). I know there is more wheel selections as well but I'm not worried about that. Any input would be great.
