Hey guys,
I have a stock body 69 BB coupe that I am looking at giving a more aggressive stance. I am looking at the DSE Speed kit 1 (2" drop+ 18" rims) in the front and a Leaf spring (3" drop+ 20" rims) rear on the car. I don't want to cut up the body or subframe at all, so that is my reasoning for going this direction. My problem is some different information I have gotten on what rim size will fit the stock body with the lowered suspension mods.

DSE and Fikse say you can go 8" front and 9.5" rears maximum width. I have talked to other wheel manufacturers who say that on their project cars they have only been able to run 7" front and 8.5" rears without rub issues on the fender edges.

Any feedback would be appreciated.

As I'm sure you have read over and over again "all these cars are a little different so.........". Now that's the reason you get conflicting information. Lets start with 2" drop in the front and 3" drop in the rear. From where? What are you starting with? Is the car stock height now? Is it sagged? Is it high? If you drop the car to the point of where the tops of the tires are above the wheel openings when you look from the side you may get rubbing with 8s in the front and 9.5s in the rear. Of course you can also get rubbing based on wether or not the sheet metal is stock or has been replaced. Now custom wheels with custom backspace are special order so the some wheel companys want to advise you with something that they know will fit so they tend to be more conservative. If you go with max sizes and you don't buy the tires till after you check your wheels on your car you can always steal some room by going with smaller tire sizes. For instance if you go 8 wide in the front you can use a 225 or 235 tire instead of a 245 to gain some room. Samething in the rear you can use a 255 tire instead of a 275 tire. Some guys have gotten even wider to fit (as big as 9.5s in the front and 10s in the rear). You said you don't want to "cut up" anything so you may want to go conservative. If your car has original 1/4s you may find you have less room than if you have replacement 1/4s. I could go on and on but I don't think I need to. You need to measure your car and if possible it's always a plus if you can try on something close. At least that gives you an idea of how far you can go. Good luck with whatever you decide.

By the way welcome to the site! Also don't be afraid to use the search function. There is a ton of info on what fits and what hits. :)
