Having recently fitted spacers myself, i fitted Pure-motorsports 10mm rear hub spacers then a 5mm Wheel spacer. Total cost of rears was around £50 and takes a lot of weight strain from the hub/bearing. For the front I fitted h&r 16mm along with a Wheel stud conversion also from pure motorsport. The handling has not been affected in my opinion. A slight decrease in turn in which i actually Like as I personally found the 197 a bit too "pointy" for my liking. Hope This helps
