FNSL6R billet forged six piston calipers clamp on 12.88 inch SRP drilled and slotted rotors mounted to flared bell aluminum hats and hub mount style aluminum hubs.

That clamping force, paired with the larger 12.88 inch rotor swept area, delivers a massive jump in stopping power and heat capacity over the original single piston factory disc or drum setup.
