As you may see from the above information, these are extremely easy to customize.
Lets say you wanted Smooth face 2mm thick rotors for the rear, and cross-drilled + vented face, 5mm thick rotors for the front... you can have it!
**Tip - Get a few different thicknesses to fine tune your width.
Turn-around time for these is around 3-4 weeks or so (due to Shapeways' turn around time). After the first batch or two, I will carry a variety of these options in stock, to help reduce that wait time. Special order options will still usually see around 3-4 weeks turn-around time.
Hardware is not included, but keep in mind the extra thickness will usually require longer screws to ensure the hub is secure to the wheel. (Except 2mm thick spacers will usually be able to use your existing hardware.)
