These brass faces do not change the offset from the original carbon face. These are sold in a set of 2. This BF adds about 5.8oz to any set of tires. Weight is approximately 2.9oz each. These ONLY FIT THE CARBON WHEELS FROM AMAZON THAT I KNOW OF. you can find those wheels here. These will fit the carbon over the brass only if you have the wheel faces that are aligned with the wheel hub on the bolt pattern. So not all carbons will fit. https://amzn.to/40a0lWn
