spring relo: offset vs. mini tub for handling?

Ironically, a slip on disk brake rotor is about 6.5mm thick or better, and nobody has a problem with those. Call it a 6.5mm thick spacer and the red flags go up, though. :D

The OP said he has a BBP 8.75, which I am assuming is an A-Body 8.75. I had a buddy with one of those in his Duster, and when we measure the width, it was about 58" or so. If I remember correctly, the standard SBP A-Body 8.75 is 57.125" wide, so his BBP axle should be about 11mm wider per side which means he might not need spacers at all. And if he did, maybe a rear disk conversion would do the job and he wouldn't have to tell people he runs wheel spacers. :)

Yup, exactly. Using the measurements from B and E body axles to calculate the width of the BBP brakes and adding that to the flange to flange measurements for an A-body 8 3/4 I end up with 57 13/16" for an A-body 8 3/4 with BBP axles and brakes. So, yeah, almost 58". :D

Yeah I don't know what the deal is with all of the wheel spacer aversion. I mean, I try not to run them if I can, but buying rims off the shelf and maxing out your tire width pretty much mean you might need a spacer. Which is exactly how a disk rotor or even a brake drum functions. Small spacers are easy. Too much past 5 or 6mm and you need longer studs and should have hubcentric spacers, but if you do those things they're fine. And yes, with a rear disk conversion adding a 1/4" per side or so no spacers would likely be necessary.
