Who is "they"? I'm friends with a few of the more "popular" (read that as older, mature and experienced) guys on the forums and they all say just stick with '04 axles. If you have an '03 then definitly "upgrade" but upgrade to the '04/'05 axles. There are plenty of people making tons of passes on slicks with stock axles. Two of the three 10 second cars are factory axles.
