25mm or 1 all around. This is a set of 4. Picture is 2 only. Used only 6 months on my 2018 Mustang GT, maybe 3,000 miles. Bought RTR rims that had offset where I dont need these. They are like new. Bought direct from American Muscle, they were $168 new, asking $100. These are the high end hubcentric model, which is what you want, not lugcentric.
