Rear Suspension Setup Question

I'm running 4.5 leaf mideyes, and 17x8 TTIIs. check sig. I'm right on the edge of rubbing, but that is because my rear track was widened slightly with the Baer disc conversion, and my Nittos are pretty beefy, too. One inch lower, and I'd probably rub.

I might try to fabricate a 1/2" lowering block, though, just to see if I can get bit lower without rubbing.
 
You can run without rubbing with 17x8 and reverse eye

It WILL however rub if you go too large on the tire on that rim....what size tire are you planning?

For instance a 235 45 17 on a 17x8 with 4.5 or 4.75 BS will not rub for you. How do I know you ask...simple...people are running that set up on stock 4 leafs with out rolling the fenders according to my chart. Additionally since you can put a 245 45 17 on the car in stock form without rolling the fender in the rear, that means the tire width is completely inside the fender and lip line...so when the suspension compresses the tires just go up inside the fender.
 
Im running 245/45 17 on 8" wheels on all 4 corners I have a 1 drop in the rear and roughly 1.5 in the front, I had to roll the front fenders a little but left the rear alone, its tight. I couldnt go any bigger in back without rolling or cutting the wheelwell lips.
 
You will need to roll the fender and at least 4.75 BS. I have one entry with 5 inch of BS and that would prob suit you the best, but because of how close you are planning tolerances and the fact that it is only one person so far....you will have to measure to be sure.
