The problem with the 3 shoe clutch is that, you have to run the same shoe and same spring on all three shoes. If you use 2 carbon shoes and 1 aluminum shoe, you will throw the balance and wear pattern of the clutch off. This will eventually lead to inconsistent performance. With the 4 shoe clutch, you can run different shoes and springs opposite of each other. For example, you can run 2 carbon shoes and 2 aluminum shoes to keep the clutch balanced. It really just comes down to tuning options.
