If you could find a bigger rotor that fits, that would be a perfect setup. Other than that, no modifications.
Ran into this exact problem. If you find a rotor with the correct diameter, let me know. The 135 rotor is also too deep and will not center in the caliper correctly. I've actually have a few track days on these brakes. There's a "shelf" that builds because of the part of the pad that doesn't contact the rotor. Hasn't caused me any issues as of yet, but it would be nice to have a rotor that worked properly. The other alternative is to have someone trim the pad.
