Wheel Size Question.

Bringing back an old post. On the topic of 17s on a Barracuda, I'm interested in the 17" Coy or torque thrust wheels and am wondering what y'all think about 17X7 / 4.25 up front? is that enough backspacing or should something with at least 5" be better? Also im looking for a tire size that will clear stock fenders, what are you running? Im building a 67 notch back with disc brake conversion up front and an8.25 in the rear with stock leaf springs and drum brakes to be a reliable soon to be daily/weekend driver so Im not looking for anything crazy or complicated. I have scoured FABO with lots of differing opinion and looking to get a clear recipe for wheels and tires I can confidently purchase online and know I wont have any clearance issues. any and all input and pictures are appreciated. THANKS!

A 17x7 with 4.25” of backspace will fit, but really doesn’t take advantage of the additional backspace you can run with larger diameter wheels. Basically it would limit you to a 225 wide wheel (brake kit dependent). On that note, what disk brake kit are you using up front? They can change the track width which changes the backspace you need.

In the back you can run up to a 275 on a barracuda with the stock spring locations, although depending on the car they can be a little tight. If you want to make it “easy” a 255 would fit all day long with plenty of clearance regardless of ride height as long as you get the backspace right. What is the 8.25” out of? Stock A-body?
