Not with a BTDT, but have heard the same stories. I currently have x-drilled Brembo rotors,
and must say I noticed zero performance difference from stock. I expected to see much
less fading, that did not happen. OTOH, switching different pads has made a much greater
difference. Stock -> Rofren = no difference. Rofren -> Westons (AFT/ -3 compound)
= amazing difference.
Next set of rotors will be stock undrilled. We'll see if that is a step backwards now that
I've found some pads that rock. Even if that happens I doubt I will go with x-drilleds
again, given the anecdotal stories of cracking. Slotted rotors may be a better alternative,
but I think that this may also have some cracking exposure, as it is also a machining process
done to the rotors which inherently disturbs the metalurgy.
And I can confirm the other comments about improved feel and response with SS lines.
But there are also horror stories about these failing, so I intend to replace mine every 2
years.
