I politely ask that responses be limited to personal experience and not conjecture. I have been looking at aftermarket monoblock forged wheels. There is no problem having one made to the OEM wheel diameter and width. The problem is offset. The C7 Z51 OEM wheel specification is front (19x8.5 +56) and rear (20x10 +79). Typical monoblock forged wheels can only be machined up to +50 for the front and +70 for the rear. This 6mm and 9mm difference doesn’t seem like much. My question is does anyone have personal experience how a smaller offset affects C7 handling since it changes the scrub radius? Can you specify what offset you have? Can you comment on 45 mph and 65 mph cornering? Did you experience any feel difference from the OEM setup when the steering response becomes stiffer switching from tour-sport-track modes? Even a response that no difference was felt would be appreciated and would help me in my decision. Also, I would rather not use a spacer.
