Well I stand corrected minus the horrible offset in the front. I guess they just look like crap on PITTMANS car 
My home made drag pac!
Hey...what the he*l...I don't run them on the street..haha. My rims don't even match front to rear..LOL. Have to admit, they don't look as good as yours by a long shot.

Can you give me details on your tire/wheel setup, sizes, backspacing, spacers and anything else required to make them work, thanks!
Differential is the equivalent of a stage 3 DTE diff w/ 3.90 gear and a DTE brace is coming, that is all except for a Textralia OZ clutch and a stock tranny!
As far as tires and wheel specs here goes:
Front wheels are 17x4.5 GTO spare rims not sure on off set/backspacing, Tires are M&H 26x4.5x17
Rear wheels are generic knock off ZR1 wheels 17x11 not sure about off set/backspacing here either just your typical 17x11 ZR1's and the rear tires are MT ET Street 26x11.5x17's
I am using no spacer on front or rear and the only mod that is required is boring out the center of the GTO spares to clear the hub on a C5. My hub centers measured 70mm so my brother machined the GTO spares out to a 72.5 to give plenty of clearance!

I've been running 17 x 9 or 9.5 on the rear with the same MT tire. They are probably cheaper than 17x11. The previous owner was using them for a winter set up. I painted them silver because I run the same style rims only chrome and 17x11 on the street. I didn't have an inexpensive answer for the front until now. Thanks!
Interesting offset combo 
There is a 16x8 ZR1 wheel out there to allow you to run a 26x11.5x16 ET Street. Plus the it would not stick outside the fender like the 17x11. I think if you used a 1/2" spacer on the fronts, they would look much better IMO. I am not sure what speed and stresses the spare GTO wheel is rated for, but I would look into it. Personally I would not trust my car and possibly life to the quality put into something ment to be a low speed temporary fix.

yeah. Mine looks exactly the same except for the blackouts. Even on the street that tire and wheel setup is ok. I didn't push it but going the speed limit around any bend was fine with the skinnies.
