"High stiffness" refers to a material or object's resistance or ability to bend, stretch, or deform easily when a force is applied to it. In simple terms, it means that something is very rigid and difficult to bend or twist. Full definition
First and foremost, dynamic driving depends on mechanical systems which combine low weight with high stiffness. (motor-prime.com)
Braking is essential for a daily - driven supercar and the GT - R features large Brembo full - floating drilled rotors, low steel high stiffness brake pads and Brembo mono block six - piston front and four - piston rear calipers, which in combination minimize fade and provide stable braking.
