Well after two failed attempts, finally had a successful track day with my 392. The Florida International Rally & Motorsport Park (http://gorally.com/) is 1.6 miles and quite technical - so hard on brakes (& tires). The stock Brembo pads would fade and nearly go away entirely after 6 hot laps. So, changed the fluid to the Castrol SRF racing fluid and to the Powerstop Z26 street/track pads. Went back out on another track day and encountered significant fade after only 2 laps. Clearly the Z26 pads were not up to the heavy duty requirements of stopping 4400 pounds on such a technical course. Needless to say, having the brake pedal get so squishy was really alarming. So, then switched to the Powerstop track day pads, meant only for track and not daily driving. Went out on another track day and Success! Brakes held up beautifully after many hot laps. There is actually little to no noise and only moderate brake dust. I had initial concerns on how the rear pads would hold up as they do not have a backing plate, which is only on the front pads. After consulting with Powerstop, I was assured that all was good and the rear's do not have the plate to assist with heat dissipation. There was some degradation by the piston into the pad, but not significant. The moral of the story is, if going to a track day with Charger or Challenger, be sure to upgrade the brake fluid and brake pads. Now, to upgrade the oem all season Pirellis... If interested, here is a short vid of a couple of laps - following a buddy as we warmed up the tires.
