You need to ask a few questions and maybe some one with a similar set up will respond.

My wheels are 18 x 9 with 285-35 tires not sure of offset right now but probably 4 to 5?
My rear end is narrowed to TCI spec 54.5" axle flange to axle flange.

My issue is having to undo coilovers to which is normal in just about all cases and have to jack really high with also at least 2 1/2 to 3"1/2 tire off the ground to get the tire off. It does come off and a little tricky to put back on without marking the wheel up on the brake assembly.

All I am saying is with your wider rear end and extra backspace wheel removal could be a even bigger issue. Needing the car even higher to get wheels on and off.

Also some of my limits are the TCI cross member driveshaft loop limits how far my rearend can drop. This means exhaust has to be unhooked to remove driveshaft. I can get the shaft out but it involves raising and lowering the car a few times with the coilovers unhooked. My 6 ton jackstands would also need to be blocked up about 4" higher.
A two post lift would ease the situation.

I am glad it all worked out for you it looks really good. Do you know the part # of the rear coil overs and the spring rate and length?
