I found the mintex 1144's crap on standard brakes with 3G discs, they overheated quite easily - not as easily as the standard pads but not much better.
Standard pads will definitely not be the best though, I'm running Ferodo DS2500's now (albeit with wilwood 4 pots and 288mm discs) and they get better and better as they get hot, very strong bite and nicely progressive, they produce less brake dust than the stock rears too.
