    Control Arm Notes
    Front lower, and upper/lower control arms are an L-shape variation. The forward leg of the control arm is set near to wheel center. The forward leg of the lower control arms is fitted with a "handling" bushing; the rear leg is fitted with a "ride" bushing. The "ride" bushing absorbs the brunt of road deflections while the "handling" bushing absorbs the brunt of the cornering forces. The "handling" bushing is 3-6 times stiffer than the "ride" bushing.

    Chassis

    20 dB separation from mount --- Input mobility --- SAE SP-1282
    Chassis Notes
    The cored composite floorboards increased 1st structural torsion mode by 0.1-0.2 Hz. The tunnel closeout (aka tunnel plate) increased 1st structure torsion mode by ~2 Hz. It makes sense that stronger tunnel plates stiffen the chassis. The C6 Z06 has carbon fiber floorboards to reduce weight, but possibly stiffen the chassis as well. The boards behind the seats often flex and pop on convertibles, and I believe stiffer boards would further increase chassis stiffness.
