2nd gen f-body backspacing "DSE Mini-tubs"
 

Have to get the hoops welded on to the centers and need to provide the manufacturer with measurements. Wheels are 18s on the front and 19's on the back. I'm pretty sure I can get 10" width on the front and 11"s or 12" on the back but I'm not very good at determining backspacing. I know a bunch of people have DSE mini-tubs in their 2nd gens. Can some of you clue me in on the backspacing you used?

There are several people on here with this setup. I went with a 57'' flange to flange on the rear end and a 335 18x12 w/ 6'' backspace.

18x8 front with a 4.5''bs 255 tire. Looking back I would have went with 4.75bs. I think a 9'' will fit but if you try to go 9's I would check fitment with a tool. I think there is one control arm setup allowing 10'' wheels on the front of a stock sub. Again, do your own research on that to be sure.

If you're going with a stock length rear end Im not sure about rear bs. Check syborgtt's build on here, tons of good info on there.

Rear has DSE tubs but stock width rear.
