Hey there,
Ya, people do it all the time. The fronts are identical to yours and then in the rear you would need a small spacer to make it flush. 15mm is what I understand. You can run 305's on this wheel but 295 is what is on them now. I have read some people prefer this for the wide body because the wheel and tire combo is a little bit lighter and can help with speed on the track. The spacer is pretty cheap on Suncoast:

These wheels haven't been used much and the tires have good tread on them so you could tear them up a few rounds at COTA and then get 305s on the back. Let me know, I have the next couple days off and could deliver them if you weren't too far away. Cheers.
-Feel free to text me if interested. I have someone else looking to buy but I'd have to ship, so local is much better Thanks again! 503.819.8535
