Those wheels look great, nice pattern.
I did a mock up of an old set of Weld Racing forged billet wheels in 17" size, and they looked really good with 255/45-17 tires. and they really weren't much bigger than the factory sized 15" rim with 205/75-15 tires.
This is the facotory wheels I have on there now:
This is the Weld wheel just put in front of the factory wheel just to see:
The Weld whee looks much bigger due to the wheel being closer to the camera. In reality, there is less than 1" in height difference between the two, and that doesn't even take into consideration that the original wheels need a little bit more air pressure, and they are supporting the weight of the car.
I still need to get wheel adapters because the bolt circle on the Weld wheels is 4 X 108mm. I also need to figure out the wheel adapter thickness, as they have a 5.5" back spacing, and I think it would be best to get it to anywhere between 4-4.5".
