You can run them!
And quite a few others in roll formed quality wheels for killer prices compared to not needed forged wheels. For the price of one set of forged wheels can do a 4x100 conversion and buy 2-3 sets of great wheels or just buy the one set you want.
Check out the wheels on goodwinracing.com, I have the 15x9 roll formed Konig Dial In, 12.8 lbs, $129 each, they have the 949, Avanti and others. I am waiting for the Konig Helix to come into the US, around 12lbs estimated weight, same price as the Dial In wheels.
949 fits in 15x8
Dial In, etc...fit in 15x7 easily, 15x8 _25 offset not a good idea, 15x9 in +35 not many would want to do, it was a ton of work on my car.
