yet another OK noob checkin in

I've been reading alot and checkin out alot of cool trucks. Thank you guys ....you and this site has already saved me money and made my brain grow. Thats either from knowledge or some kind of an anyerism sp?not sure yet.

I've got an 05 silverado CC 1500 I just put 2.5" tru duals, bassani's, no cats, pacesetter Lt's and a nelson performance tune. Only had it a month an I'm in love.....its so much better than my ford

As soon as I replenish some funds I think some wheels and a lowering kit is next. Should i get wheels before the lower or after?
