Brembo SuperSport Rotors Not Centered in Caliper

About 1 year ago I replaced my original front brake rotors with Brembo SuperSport rotors that were listed as a fit for my 2010 model. While the brakes worked good last year at the track, I noticed when prepping the bikes for this year that the inner tabs that hold in the brake pad on both sides of the front wheel were nearly hitting the rotor. There was a larger gap between the outer tabs and rotor on both sides.

I ended up buying some thin washers (~0.75 mm thick) and placed them between the rotors and the wheel at the bolt mounting points. This effectively moved the rotors slightly outward. After mounting the wheel and brake calipers, I noticed that the gaps between the inner tabs and outer tabs on both sides are pretty close to even.

My bike is an early 2010 model without abs / traction control with cast wheels. It appears that the Brembo SuperSport rotors have a slightly different mounting depth as the reason the rotors were not centered in the calipers.

I had the exact opposite scenario with my Brembo HPK Supersport rotors on OZ Racing wheels. After centering the wheel properly the rotors were both too far spaced out and after 5 sessions on new pads the cast caliper tabs were contacting the rotor hence reducing the braking significantly. I ended up having to dremel the outside tabs away slightly to gain proper clearance. No washers were used at all so this was my only option.
