The 13 mm rotor didn't make much difference for a couple of us with the 13.5 ss pro. Two other were mad that they bought the rotor. But when I put it in the 7.5R...OMG!!! That thing was crazy! The stock 7.5R is wild, but with the 13mm rotor....hold on. LOL. That is if you can get the power to the ground.
