Wheel modification?

[slowmobile]

Hey guys,

I have Torque Thrust D wheels on my street car. I'd like to keep them on my car. The set I have now are 15 x 8.5 with 3.75" BS.

Problem is, there is not enough backspacing on them so my tire hits the wheel lip but there is 1.5" inside the wheel before there is any interference. Section width on the tire is 11.2".

My question is:

Is there anyone that can modify a set of these wheels to get the back spacing I need? I need either an 8.5" wheel with ~4.75" or a 10" wheel with ~5.5" of back spacing (and their 10" wheel only has 3.75" of BS too).

Thanks for any help, info or leads.
