Can someone help?????

I have a pair of brembo 4 pot calipers with a pair of solid drilled and grooved discs that came off a puma, and now on a mk 4 rs turbo.

the discs are warped badley and I need to replace them, IThey have RED DOT 305 stamped on them, but I cant seem to to buy a replacment pair as every company I call say they dont sell discs of this size,

does anyone know if any other ford has 305mm discs, If I could find a pair I would buy some alloy bells and rotors, but cant seem to find any.

can anyone help??

thankyou, wez
