So I bought a set of black slotted and cross drilled rotors for my 2014 Brembo GT. Went to put them on today and the fronts are only 13 1/8",whereas the factor ones are 13 7/8". My question is will they still work or should I just send them back? I really don't like the idea of having 3/8" less rotor for the pads to engage but I could just be over thinking it. Thanks.
