I realize that to most readers of this forum the answers to my questions are obvious, however as a new, (and proud) owner of an 89SHO I would greatly appreciate any assistance. Firstly, will the 16inch slicers from a '91 bolt directly onto my vehicle, which currently has the stock 15inch basketweave type wheel? Secondly, how will this affect my speedometer reading? Thirdly, what differences, if any, can I expect in ride and/or handling? Finally does anyone know the correct paint or code for the slicers? Many thanks for reading and your help!!!
