I have quite a bit of data recorded with stock brakes vs updated stock brakes and the results are staggering. As in, using near 1000psi less brake pressure to get the car stopped. I’ve run some decent times in both my SLE and ZLE and braking performance has been nothing but stellar. I use Giro rotors, GM Dot 4, stainless lines and either Ferodo or Cobalt pads.
If you need more than that, there is something fundamentally wrong.
