I was worried about how well the wheels would work at the track considering they've been cut and rewelded so I called weldcraftwheel and quite a few guys run their widened wheels at the track with no issues.
Cost is $175 per wheel up to 3". You could buy these http://store.summitracing.com/partdetail.asp?autofilter=1∂=SUM-541-5866PS&N=700+400304+4294923107+4294923106+4294755963+4294793325+115&autoview=sku
For $107 plus the $175 for widening and you are at $282. You'd need the sway bar relocation bracket because this move move the wheel in 2 inches.
Either this option or try the Billet ones with the 7.5 backspace. Those are $220 a wheel
