Dyzio, I am no expert but think the answer to your question is yes and no.
They will work, but better if you are using stock calipers to use the wider track discs.
With my digging, I have gone for original brembo with the wider track.
However, if you look at alot of the aftermarket brands, think you will see most if not all are the 2ono style thinner width disc, guess it is simply becasue there is a lot more call for RSV/2ono etc. over falco.

Are you sure they are warped

As it is well documented on this site about the bobbins sticking giving the same feeling as warped discs, I thought my discs were warped, cleaned the bobbins bent the retaining clip out a little (turns them into floating discs) and the warped feeling went away

This thread has some of that documentation - along with a few other potential causes.

Yeah I cleaned up the bobbins earlier in the year but I still get lots of pulsing and juddering from the brake lever. I never tried bending the retaining clips but I think the discs have had it anyway.
