Thank you all for the useful information. I think I may not make changes to my stock system after all and just continue to drive with care and within the limitations of this setup. The cool factor of having showy aftermarket brakes may be outweighed by more harm than good if not installed properly.
The question arose because I had won a day at a track and decided not to take my Pantera. I drove a rented C7 Corvette instead and had a ball, but it didn’t have the seat of the pants heart pounding exuberance of a Pantera. The Vette was quiet, handled very well, had traction control and brakes that were as strong as the motor. What’s not to like, unless you own a Pantera.
