1G DSM big brakes. Need to upgrade bad.

I see, i believe the pads are reds and they have felt great before.
I was doing a pull with a C6 and i think this might of been the second one, but slowing down from 120-130 sucked at about 75 i realized the pedal pressure was not there and i was already pulling up the e-brake a little, so i got off the pedal and back on it and it wasn't doing shit.
Still on stock lines. I have a rear set from agency power but they fucked up on the front set so i am trying to work with them on that, but i want to just get my money back and get a better kit.
Rotors are drilled and slotted, all brakes came with the car.
