They are not bad without. I ran 15mm h&r bolt on spacers and that is about as far as I can safely run them. The car has a large audio system in it so I am not blessed with a great deal of suspension travel left. On my fist set of wheels I ran the same offset and had very few issues, mainly that with a heavy load and a good sized dip in the road the suspension would compress and if the car was heading into a corner at the same time it would rub the very inner top of the tire from time to time.

They are about to get sold off so if you are still interested in the wheels here are the links
