Not sure what Braum seat model you are interested in but there is typically a dimension photo on CarId.com when viewing a particular model. In summary/comparison, I didn't notice a substantial size difference in the seats. I'm 5'6" 170lbs so it was probably less of a concern than it might be for others who are taller/larger. In general I prefer the feel/comfort of the Braum seats vs. the Stock Nismo seats.
