Now that I read this probably I wouldn't look for a MRC car in the future. Replacement cost is too expensive.
-My 5th gen Camaro ZL1 had the MRC shocks and I didn't felt a great difference while driving and trying the different settings.
-Neither of my '14 Corvette C7 Stingray Z51 nor my '16 Camaro SS came with that option, and I didn't really missed it, the base shocks were greatly balanced between sport and confort driving and I normally enjoy spirited DD.
