1970 Duster, Trans-Am-inspired "Pro Touring" build

I think @72bluNblu is running 275-wide fronts on his car, I believe he's using thin (1/4" or less) wheel spacers on "standard"-offset wheels to make it work.

I got my wheels from here: Home - I don't think they're actual legit OEM replacement wheels but the quality is good. Not as good as more expensive wheels and they're probably on the heavy side and surely made overseas but if you want affordable there aren't a ton of options. Mine are FR500 style for 1994-2004 Mustangs. Just had to take the fronts to a machine shop to have the center hub registers bored out to fit over my '73-up disc brake hubs. Rears fit fine with just some minor trimming of the hub registering "lip" using a dremel.

I was running spacers at first, with the 13" DoctorDiff style cobra brakes I'm not running spacers anymore. I have 275/35/18's up front with 18x9's that are +35 offset. My wheels do touch the frame at full lock, but that's because my QA1 tubular LCA's don't have a steering stop. Not likely to be an issue with factory LCA's.

Initially I got away with not having the fenders rolled, but at my current ride height my fenders needed to be rolled and pushed so as not to cause rubs when compressing the suspension with the wheels turned sharply. You could probably get away with not having as much clearance as I've done, but I try to set mine up so I can drive "normally" and not creep over every bump and dip.
