I currently have a set of 15x8 drag lites with 4.5" BS and they look good on the car with 275/50/15 (26") Hoosier Dr's. I will be buying a set of RT-S' and I want to go with a 15x10 in the rear. I want to fit a 275/60/15 (28") tall Hoosier Dr or MT radial pro. I am torn between a 5.5" and 6.5" BS. I like the look of the 6.5 but it seems like a lot of work. Also seems like you have to change the suspension up a little bit. On the flip side I have seen pics of the 5.5" BS that look good and flush with the wheel wells and other pics where it looks like Joe Dirt's car. Pics and advice welcome. I know the 275 radials aren't all that wide. Just want the car too look good, retain all stock style suspension and not rub with a slightly lower stance.

Here's the car with the 15x8's. I like the placement of the tire in the wheel well. I'm going for this look with a wider rim and taller tire.

 

Not sure every ones experience but 15x10 with a 6.5 back space did not fit stock wheel wells. I had a Mickey et street 28x11.5. Just got done doing the mini tubs. Kind of thing a 5.5 back spacing looks better.
