Yeah but if you went through the posts, you would have seen what is recommened. You have to understand the concept of wheel offset.
That image alone with the information on the last link should have helped you grasp the idea. Its something that you must understand to pick a good offset.
The wheel diameter does not dictate wheel offset, but rather the wheel width.
The red line is where the wheel would theoriticly mount to the hub of the car. Looking at that illustration at the left, you can see that with the same wheel width and different offset. It would cause the wheel to tuck into the fender well more. Provided you have enough space in there, it will not rub the inside fender well.
Looking at the illustration at the right, you would have the same offset, but when using wider wheels, it will cause the wwheels would extend equally on both sides. However, with this method you would have to make sure you have enough clearance on the outside so it would not rub the fenders.
Quite honestly I don't know where this thread is going since you already have 17" wheels that work for your car at he moment. Just look at the offset it has and get the same size and offsets. You will have answered your own question and not have issues with it rubbing.
