5.5" of backspacing.
No, its not mini-tubbed. Its all stock, including the shock location. I did drill a hole up higher on the lower shock mount on the Caltracs to get the bottom of the shock away from the inner rim screws and I used stick-on wheel weights instead of normal crimp-on weights.
Stock rearend housing, stock spring location, stock upper shock mount, stock wheel tubs.
I could possibly fit a little more tire under it on these wheels, but not much.
