I ran 17" with 11" drums painted black. Not a big detractor. The nice thing about larger wheels is you get a way more choices in tire compounds, modern casing designs, and superior tread designs.
These are 17’s with an 11” drum. When they’re spinning you can’t tell if they’re disc or drum brakes, and when just sitting there, they nearly disappear.
My fronts are Wilwood disc. Just make sure the backspacing is correct so you don’t have fitment issues.
