A lot depends on the car and color. The 56 hardtop is one of the best looking 50's cars Ford ever built. In my opinion, a single color just makes it better. Especially an all black exterior. Sharp looking car.
I think Dos Cincos nailed it. The stance is spot on and you normally would not expect to see WW's and wheel covers on that style of car. It sure looks good to me.
The car is relatively stock looking other than stance (all handles, badges, trim is intact) so it just proves how the stance changes the look.
Car looks perfect the correct stance. I run 2 1/2 white walls with hub caps on all my 50's cars. 3 inch white walls on my 39 dodge with original hub caps. Just my favor .
