Why dont you go composite??
($5K total package) :-(
Tree, just for the heck of it. Post the weight of composite Rotors here.
They can't weigh nothing I imagine. At least not a 5 to 6 lbs weight saving as I read in other posts.
What is out there on alternatives, besides the options 999 posted.
I saw Armstrong discs for an example.
How about Carbon and Ceramic is this on the market ?
However I don't plan to build a track weapon.
I just want to improve my bike for road use, and might an occasional track experience in the future.
And there I think is steel still the best solution.
