Eldar- do you know the answer regarding brake rotor interchangeability?  Buying parts to set up a dual caliper set up...

Well I have not done it myself but I am inclined to think they are the same for all the k models or at least k1 - k8. F models are different though.

Watch out some are 5 bolt others are 6. And try to get them with the bolts that came with them, there is a size issue. but that is always the case. HEEHHEHEHEHEEHEH!

I prefer to not mention the f rotors as so many ebay seller label them wrong and unless you know EXACTLY what your part looks like, you could get stuck with a rotor that does not work. If you stick with the K designation, then you are ok in most areas.
