Changing wheel bolt pattern?

Has anyone had there front hubs redrilled to a 5 bolt pattern? 5 x 4.5" or a 5 x 4.75"
My rear end is a Ford with a 5 x 4.5" pattern, what I really want is as set of wheels that fit.
Would like to go with a 17" x 7 or 8 on the front for a big tire, I don't have inner wheel wells,
And have a rear wheel that matches 15" x10 or 12 wide.

Did you have any luck? I am thinking of doing the same thing, as I am installing a Jaguar IRS in my TR6 which has a 5x4.75 bolt pattern.

Hi Ed,

I have these adapters that I bought from Martin someone on ebay. They are TR6 bolt on to a size for later type size four lug wheels. I'm wondering if they could be drilled out for 5 lug? Here is four pictures of them. I can let you know more info if needed. Hope this can help you.

TR6 front hud is 4.5" center to center from these adapters.

The wheel adapters look like a OK idea, but some nut wants to run some real hi MPH with my car. I want to attend a airport autocross with a 3/10's mile straight at the end that they use for a hi speed run.
I found this web site and there is mention of aluminum hubs, [www.tonydrews.com]
The price is up there but it they could be made with a 5 bolt pattern it might be a good option.
Anyone have a contact for the Southwick co?
