My "new" '74 Duster- or why I need a project like a hole in the head
The 275's in front?
Originally not much, I run the 275/35/18's on 18x9's with about 6.1" of backspace if you take out the extra track width I get from the 13" DoctorDiff brakes. I extended the lower fender brace by about 2" to push the corner further out and cut the lip back at a 45° angle or so.
At that point the car was probably lowered ~ 1.5" from stock. As I've lowered the car further I rolled the lip on the fenders, and then rolled them again and added a little "push" to the fender with the fender roller. But that was to get down to lowered about 2" from stock, and my tires never rub on the fenders. I'm maxed out for lowering at the moment though, I started to get witness marks from the tops of the tires on the bottom side of my inner fenders. Currently the top of the wheel opening is about 24 7/8" from the ground, and I get a little more compression travel with the QA1 LCA's I run.
I've seen people do less to run 275's but since I use this car as my primary driver most of the year I don't use "show car" clearances, it has to do speed bumps, pot holes, steep driveway transitions etc.
