Bigger brakes or more patience

Put stock sized Powerslot rotors on the car with Axxis Metalmaster pads and Goodridge stainless lines. Oh yeah, and replaced all the brake fluid with a racing fluid. I was hoping for some good negative g-forces when stopping but it just doesnt seem to be there. Oh I mean the car stops but its not like the "end of the roller coaster like stop". Broke the system in just as Powerslot recommended, I gave it about 230mi of granny driving before I laid into it. For real stop-on-a-dime power do I need to step up to a Brembo large rotor kit? Or do I just need to be more patient and let the system break in a little longer before making a judgement.

you have stock size rotors and pads. yes the pads will help a litte. the lines just help with the actual pedal feel but aren't going to make you faster they just wont let it get mushy after a while. the brembo kit is very overkill. a nice upgrade would be the wagon discs and legend dual piston calipers.
