Ok then, I hope you're sitting comfortably.
EK9 standard:
Pad spec - 148.7x57.7x18mm
Total pad area - 8579.99mm^2
Disk diameter - 282mm
Total sweep area per rotation - 40658.8377mm^2
Wilwood Superlite and 298.5mm disk:
Pad spec - 120.4x61.7x20.3mm
Total pad area - 7428.68mm^2
Disk diameter - 298.5mm
Total sweep area per rotation - 45513.82357mm^2
Difference - 4854.985871mm^2
So for each rotation of the disk when the brakes are being used, you're covering nearly 5000mm^2 more than the standard single piston caliper with the Wilwood Superlites and the larger diameter disks. With the pad being slightly smaller in area, it will wear quicker as it's travelling further per rotation, but to compensate that, the pads are 2mm thicker each side, so you're getting an extra 4mm of pad material.
Also something to bear in mind is the piston area you've got applying pressure to that pad.
Assuming the single piston is the same diameter as the DC2 (57.2mm) you have a total piston area of 2569.6971mm^2. With the Superlite caliper using 4x 44.5mm pistons, you have a total piston area of 3110.5694mm^2, a difference of 540.8723mm^2.
Pad size isn't the be all and end all of brakes. You really need a complete package to complement the pads. If you can apply more force to the pads, more evenly and have the pads travel further per rotation, you're going to achieve better modulation meaning you have the ability to find the point just before the brakes lock up easier (which is the point you want to get to - a locked wheel will slow you down slower than one just before the limit). Also with the pads travelling further per rotation, and the disks being 32mm thick instead of 23mm the disks have more time to cool down before the pad comes into contact with that section of the disk so you're not going to cook your brakes.
