Hello everyone, I recently installed RsR lowering springs on my iM and decided my cars rear end would look better with a 5mm rear spacer. Unfortunately on Amazon their is many options for 5x114. I did purchased 5mm for the front wheels " HUBCENTRIC 5x114.3 Wheel Spacers (67.1mm Bore)" but not sure how much smaller the rear bore/hub size is. I don't want a spacer with a big bore size and it just hangs in the hub until you line it up with the wheel and have to hold up to make it fit flush. If I could get options on what size you guys purchased for the rear, would be great. I'd perfer something from Amazon since I do have Prime and normally get everything next day.
