I have Mintex 1144 pads, EBC Grooved/drilled Discs, Braided Lines, Rebuilt Calipers, 5.1 Toyota Dot - they faded (totally cooked! I could smell it) once after heavy braking (start/stop) within 10 min - even though they faded I still could brake (about 50% efficiency), about 2 min later they were back to normal. I wonder if that is a proper bedding in.
I've installed the braided lines first - before I've done any job on the brakes - the improvement is about 10% - 15% .....
I suggest to get a decent brake setup like Brembo! You always get what you pay for!
I drove a sport BMW of a friend of mine - touched the brakes and almost kissed the windscreen - he has STANDARD BMW 120d M Sport brakes with Standard 17" tyres - after those brakes my setup is a complete piece of shit!
Brakes don't look massive and nor drilled/grooved......
7.7 Sec 0-60 and does 60mpg!!!!!!
