    The result is a 30 kg (66 lb) weight reduction as compared to the DB9. The car is also fitted with a carbon fibre splitter at the front wings to increase handling and a carbon fibre rear diffuser to increase high-speed stability. The brake discs are carbon ceramic, which reduces a significant 12.5 kg (28 lb) from the unsprung weight.

    en.wikipedia.org/wiki/Density

    As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3 ) and the cgs unit of gram per cubic centimetre (g/cm 3 ) are probably the most commonly used units for density.

    Higher-strength torsion bars increased ground clearance, and shock absorbers reduced the effects of ground strikes. The weight of the M113A2 was increased to 11,740 kilograms (25,880 lb). Because the added weight affected its freeboard when afloat, it was no longer required to be amphibious. Four-tube smoke grenade launchers were also added.
