Using hollow roll bars and titanium springs in the suspension also
reduces unsprung weight further.
Not exact matches
A
further advantage is that PCCB brakes
reduce the
weight of the
unsprung masses versus comparable grey cast - iron discs by approximately 20 kg or 44 lb.
Such use of light alloy helps to
reduce the
weight of
unsprung masses despite the larger discs on the front wheels by approximately 2.4 kg or almost 5.3 lb, the
further improvement of brake ventilation helping additionally to minimise fading for lasting brake performance at all times.
This results in
reducing the overall
weight of the car and, in particular, the
unsprung weight and rotational masses,
further enhancing the DBS Volante's dynamics.
The drawbacks are that it does not allow each wheel to move independently in response to bumps, and the mass of the beam is part of the
unsprung weight of the vehicle, which can
further reduce ride quality.
Further weight shavings can be found in the steering and suspension assembly, with control arms and knuckles hewn from aluminum to
reduce the car's
unsprung mass, yet the new SL is both longer (1.97 inches) and wider (2.24 inches) than its predecessor.
