So it's brake by wire?They feel soft because the brake pedal isn't actually attached to the braking system. It is a pedal simulator and the brakes are controlled electronically.
Honestly, the 2021 PPV is a far better value. The hardware seems to be identical with the Brembo brake calipers being painted red.Did you use the gm kit for the upgrade or the 2021 ppv 6 piston calipers? It looks like they are the same calipers, just unpainted on the ppvs.
