I have a MK4 Roadster purchased in 2014. Finally finished with the build and noticed the brakes are not as responsive as I'd hoped. I have the FFR complete kit with the Ford Mustang GT 11" front rotors, twin piston calipers & pads. Also have the FFR #15580 rear brake kit with 11.65" Rotors and pads. I'd like to install more aggressive pads for street use. Can someone assist me with the criteria to enter for a year, make, and model to order compatible front & rear brake pads with my existing rotors? Also, any recommendations on the best brake pads to use? Thanks so much.
