Don't limit yourself to the original bolt pattern on the rotor...there are a ton of different things out there if you just have the rotor redrilled for bolt pattern. If you do some looking you should be able to find the rotor height you need I'd think.

Mercedes AMG 360mm (converts to around 14 1/4" from memory) rotors redrilled on my car. (The AMG rotors are slightly thicker then a lot of the other 14" ones out there from memory so make sure your caliper will suit it, these are the original 8 piston ones so fit is perfect.)

I had to watch rotor height too, to clear the rims I am using, these worked out well.
