Wheel Question...
My buddy has a set of polished 19x11 19x10 HRE 547's, I am looking into buying them only issue being they are made for a Mustang. What are my options as far as being able to use them. I have heard of people drilling out lug patterns, in fact I have a friend who had a set of wheels like that on his car. I also know they make wheels spacers that adapt to a new lug pattern. Is any of this worth doing? Is it unsafe? He is letting them go for a very good price so that's why I'm looking into it. Thanks fellas.

A spacer that allows you to convert from one lug pattern to another would probably be at least 3/4 of an inch thick. With those wide rims you might hit the front and rear of the fender well when you turn the wheels. The further you push the wheels out and the wider they are the more likely that will happen.

Yea, but the mustang has a standard 24mm offset. The 10.5" C5 Z06 wheel that I have has a 58mm offset, so the difference is 34mm, which is roughly 1.334". I have located a 1.25" (31.75mm) spacer that adapts the 5 x 4.75 GM Pattern to a 5 x 4.5 Ford pattern. Does that sound like it would work. It sounds good but I am not a pro with this type stuff, hopefully someone here is lol.

Less offset = the more the wheel will stick outwards.
Those 19x11" - 24mm wheels will stick out of the C5 rear fenders about 1.5" even if you could bolt them straight up. Adding a 1.25" spacer/adapter will ADD to that and make them stick out of the fenders 2.75".
A good offset for an 11" wide wheel to keep tucked under the stock rear fenders would be 64mm.

The difference might be 1.334"...but in the wrong direction.

For the sake of easy explanation, a 24mm offset wheel, and a 24mm thick spacer, would fit the same as a zero offset wheel, not 48mm like you are thinking.
Less positive offset, the more the wheel sticks out.
With the 31.75mm spacer and the same wheel, you'd have -7.75mm effective offset (yes, negative).
And as I stated, you'd want 64mm positive for best fitment for an 11" wide wheel.

The part that is confusing you is that a spacer REDUCES the positive offset value. It doesn't add to it.
