What wheels are those that you're running? In order to to fit those size tires, what's the backspace or offset? Just curious because they would look on my Duster especially if I can squeeze 275's instead of 255's. Thanks!
Here's the thread on his wheels GMachine Dart - New Wheel Package
( I have it bookmarked, his numbers are in the list of the references I keep to figure out backspaces and tire sizes :D )
I forget the name of them, but he runs 6.35" of backspace in the front and 5.95" of backspace in the rear with 1/2" offset springs.
For 275's on a Duster you wouldn't need the offset springs out back, but I would suggest a little less backspace even on 18x9's in the front. I run 275's on mine up front with 18x9's and 6.1" of effective backspace (13" rotors and a 3mm spacer). In the back it depends what rear axle you use. With an A-body 8 3/4 housing, BBP axles and the springs in the stock location you'd want about 5.25" of backspace.
