I'm about to pull the trigger on 4 new Boggers and beadlocks,,,and I'm not sure what rim size to use,,,I run a 14 bolt rear W/ disk brakes and a D60 front and have ground the calipers for the wheels I have now ( Eaton 15 x 10 ) Should I stay with the 15" wheel size ? What backspacing should I use ? The Eatons are 4 1/2 inch ( I think ??? ) You guy's that run beadlocks post up what brands you run,,MRT's ,Champions, Barts,,,and what backspacing you have,,how many bolts on the rings and what you would do different if you did it all over again. I just don't want to spend a bunch of money and find out later I should have done something different!!!! Thanks in advance !!!!
