67 Barracuda Front Rim/Tire Help

I've read through many threads, no luck.

67 Barracuda, original sbp KH disc, QA1 UCA/LCA/Struts, Hotchkis swaybar.

For years ran Cragars, 14x6 3.75 bs, 215/70/14.
Switched to steelies, 15x6 3.75 bs 215/65/15.
When I switched to 15x6 I figured what tires would be same size and they are near identical: Tire Size Calculator

Both sets above just clear the front fenders and have never hit the fenders in all driving conditions.

Have an old school set of Cragar Sparklers I want to use on the front, except they are 14x6 with a backspace of 4 and 1/16th.

Anyone running a front 14x6 with a 4" bs, if so what tire?
Does bringing the rim/tire inward effect handling and/or steering?

If it matters, I have BBP axles in the rear with 15x8 4.5 bs and 275/60/15.
