    Rotor diameter is 11.25 in and thickness is .828 in
    The offset of the hat is .751 in
    drilling 4x100 is not a problem
    price is $1200 for a set of two rotors.

    it's almost the same cost as stock, expect they're now two piece floating rotors. Also now a replacement rotor if needed is $150.

    They're beautiful, but they're a bit steep at $600 a corner. I've got Ø10.3" rotors too, so the pieces you had commissioned are incompatible with my AA2.

    I use to have an aftermarket Wilwood front brake setup on my 2004 Mazdaspeed Miata..but the first time I needed to replace the rotors,which were a two piece design..the cost was over $200/rotor(just for the disc,not the hat). I was using the exact same pad compound (Carbotech XP12s) as my stock Mazda sport brakes, but I never felt the Wilwoods were better overall at slowing the car down...and other than being marginally lighter,I could not excuse the Wilwood rotor replacement cost vs. performance gains. I went back to the stock Mazda sport brake setup and am happy with $35/rotor pricing and the brakes feel just as nice,and lap times prove it out. So..sometimes "better" does not always translate into "better" overall performance. Just a lighter wallet..

    I'm always wary of bolting on new rotors to existing hats. I guess just get the torque specs, use loc-tite and hope for the best? :P

    ^ Nothing to fear. Use new hardware (they use locking nuts,so no juice necessary) and torque them properly and they will never ever come loose. Never.

    I scoured the Internet trying to find the rotor part number. As always you come through.

    What brake pad do you use and can you provide the part number as well. I feel like I want a slightly more initial bite than the stock pad. If I have a part number then I would guess I could cross reference that number with other manufacturers

    SRA stock pad is (I believe) the Hawk DTC-70, I've run those and the less harsh DTC-30 you'll find them from a few vendors online.

    Hawk DTC-70 part: HB100U.480
    Hawk DTC-30 part: HB100W.480
