I have been running DS2500s on both standard 4 pot front discs and then on pagid 8 grooves and have on occasion managed to make the disc surface go blue - which I guess means the pad operating temperature has been exceeded? Anyone else had this ? Whats the solution to prevent this - a pad with an even higher operating temperature ? If so what does anyone recommend ? - Pad still needs to operate well from cold as this is for road use.

Come on chaps - someone else must have had this ?

Could it be the colour of the discs changing do to the heat?

Same happens to my factory WRX03 discs with DS2500 and a set of Nippon Denso discs that have also warped, I am not sure if are the pads that caused it though!

If you go to harder pads you'll make it worse. Metal changes colour with heat. I blued my discs severely at Elvington track day yesterday. I don't think you will have exceded the pad temperature as you don't mention fade. IMHO they sound like they are working fine.
