In building my EP car the spec line in the GCR says to use 17x8 wheels which would be the factory size. I have been searching for that size in a different offset and I really don't want to use wheel spacers to get the offset, but now when I do look at 17x9 there's tons of wheels with the offset I'm looking for. IF I were to use the 17x9 is there some type penalty that would apply to me or just keep searching for the 17x8 wheel ? really don't want to use spacers.. Thank you

Using non-compliant wheels could mean possible disqualification. Continuing to do so could ultimately result in loss of competition privileges.*
Now, that said, you could possibly get away with it running regional events locally, as that kind of stuff is rarely checked (but the risk is certainly not zero). And all it would take is upsetting one competitor for them to toss a protest.
But you should completely erase from your mind any chance of getting away with it at "moar importanter" events such as Super Tours and the Runoffs. It will eventually get caught and you will be sanctioned.
There's nothing wrong with properly-done eccentric spacers and wheels studs. In reality, all you're doing is extending the hub face, which is exactly what a wider offset wheel does. Drill, tap, countersink, and bolt the spacers to the wheels if it makes you feel better.
And note that the wheel size is "maximum" so you can actually run smaller if you prefer.
*Technical infractions do not carry points on a competition license. However, continuing to ignore the technical regs could result in a chief steward citing you for "failure to follow officials' direction" and/or "unsportsmanlike behavior". And you can bet that trying it more than once will result in word getting out and your car getting scrutinized every time you showed up.

Totally understand about the rules and of course will abide by them. They do make eccentric spacers for my vehicle so I will proceed in that direction. I always come in here before I do things to get everyone's opinion. Thanks Greg because I do plan on someday going to the runoffs too.

There are a number of suppliers of hub centric wheel spacers. Google search and you might find some for your specific car. You should know what the hub flange diameter is and the inside diameter of the wheels that you want to use. Some cars, like Honda S2000s have different hub diameters, so make sure what you have. On my S2000 I had spacers made specifically for front and rear, but had the OD of the spacer centers, where the wheels mount, the same, so that I could use wheels in any position.
Another option to consider is to use a smaller diameter wheel, if your brakes/suspension will fit. 15 inch wheels might have more offset options available. Also check for tire availability for whatever wheel you choose.
