I'm running 18x9.5 on the front with 5.25" backspacing. Using the Blazer spindle setup. Also have RideTech front suspension.Popping back in & bumping this up TTT. Maybe we'll see some updates soon.
I'm still decoding spindle/brake/hub assembly widths to determine the path needed on mine. Tested an 18x8.5 wheel w/5.130"BS on the current front stock brake set-up (dropped spindles & stock brakes) & the fit is good. Cant go wider though w/o either raising the height (not the path I want) or doing wheels w/more BS which means 'custom' or limited options. This stuff sucks sometimes when sorting through all the info.
Hope all is well.
