I have a 2002 V6 Mustang sitting on the stock 16's. Found a set of 17's that came off a 2019 Mustang EcoBoost. Same bolt pattern but I've read that the 2019 rim will scrape on the caliper, will I need spacers? If it's less than a quarter inch I can use those autozone shim spacers.
You also need to find out what the hub bore diameter is on the 02. The 19 has a hub bore of 70.5 mm so if the 02 is smaller than you need a set of hub centric rings. You can buy a set of hub centric rings/ wheel spacers from BORA. They are expensive, but are very high quality. You specify what vehicle they are going on and they will make them fit the hub size that vehicle has, and then the outside will fit the hub bore of the wheels you are using.
