I've been lurking for awhile 2yrs to be exact! I traded some boat parts 2 years ago for a ratty clapped out bone stock 88 k5. In the last 2 years I've replaced the entire braking system minus the booster all new seals and bearings in front and rear axles,had the 700r4 built new conventer. The motor barely ran , new fuel pump all new sensors ultimate TBI mods msd ignition and new radiator has got the go dept going again the only thing not changed was the distributor and that's because it's still in the box lol. I even hung a couple straight junkyard doors on it. To make a long story short just trying to get it dependable! I even replaced every light bulb in it headlights dash tailights yep every last one! Now that it's 100% road worthy it's time for the fun stuff. I have read and looked at every possible lift tire size gear combo out there. I have pretty much made my mind up on a 4'' spring lift(rough country) and possibly a 1'' body lift just to firm everything up. I've got a set of decent 285's that came off my Duramax that I plan on running for a few months (has 3.73 gears in it may go larger later on). I was about to order some new 16x8 wheels and noticed two options 4and1/2 backspacing and 4and1/4 . Well crap I thought I did my homework which one should I go with??? and why?
