The DB9 is available with a manual transmission and a sport package which has shorter gearing than standard automatic transmission. The Sport Pack and the manual reduces weight to under 3,800 pounds. press release from earlier this year: From July, Aston Martin will offer the option of a factory-fitted "Sports Pack" specification for the DB9 Coupe, combining revised suspension characteristics with a new alloy wheel design to give subtly different driving dynamics. The new five-spoke forged aluminium alloy wheels are lighter than the standard wheels, the springs and front anti-roll bar are modified and the ride height lowered. Taking the DB9’s VH architecture as its foundation and retuning some of its key components, the DB9 Sports Pack offers an even more focussed driving experience, with improvements to both high-speed body control and steering response. That means a DB9 Coupe specifically for the enthusiastic driver with a high level of driving skill, who likes to drive quickly, safely and with precision. The first key to the sharper dynamic balance is a significant reduction in ‘unsprung’ mass which indirectly allows the suspension to react more quickly to inputs such as bumps and cornering forces - resulting in improved grip, steering response, body control and ride quality. With the DB9 Sports Pack, each five-spoke light alloy wheel gives an unsprung weight saving of more than 1kg, with a small but significant additional saving from the use of titanium wheel nuts. In total, that equates to more than five per cent reduction in unsprung weight on each corner of the car. The new, lighter 19-inch wheels are the same size as the standard wheel and use the same Bridgestone tyre. The DB9 Sports Pack’s spring rates are increased by 68 per cent at the front of the car and 64 per cent at the rear. The front anti-roll bar is modified, and the dampers are revised to support the new spring and anti-roll bar characteristics. Together, the changes optimise body control and front-end grip without compromising ride quality or adding weight. The ride height is reduced by 6mm, lowering the car’s centre of gravity and further reducing body roll while leaving ample ground clearance and backed up by modified bump stops. The composite undertray is also replaced, by a load-bearing aluminium panel that performs the same function in managing underbody airflow while adding further structural stiffness, to resist larger lateral loads fed into the front of the car by the uprated front springs and anti-roll bar. The cumulative effect is significantly improved dynamic response, and especially steering feel - making the DB9 feel lighter, more positive on turn-in, more agile and more involving for the enthusiastic driver. Body control is especially enhanced during high speed manoeuvres, giving the DB9 a more neutral handling feel. Aston Martin Sales & Marketing Director, Bill Donnelly, says: “This optional Sports Pack will offer driving enthusiasts the opportunity to tailor their DB9 Coupe to deliver an even more rewarding dynamic experience. The Sports Pack offers another addition to the Aston Martin range and provides customers with an even greater choice and the ability to further personalise their DB9.”
