The suspension package replaces portions of the car's suspension system with Bilstein and Eibach parts, which are claimed to make the vehicle more responsive and accurate through the corners.

DBR9, and each wheel weighs less than their stock counterpart.
Pirelli P-Zero tyres are used, and the rear wheels are widened to . The aerodynamic package adds a
carbon fibre front splitter and rear lip spoiler, which together reduce lift by up to 45%. Packages could be ordered direct from Prodrive or from an Aston Martin dealer, though all packages are installed by Prodrive. 0 to acceleration times are claimed to drop by 0.5 seconds to about 4.3 seconds and 0- times are improved by 0.9 seconds.
N400 / N400 Roadster (2007) To commemorate the company's racing successes at the

The N400 was available in three special paint colours; Bergwerk Black, Lightning Silver and Karussell Orange. Each N400 came with perforated leather trim, including a map of the
Nürburgring stitched on the center armrest, and a numbered plaque. Aston Martin tested the car at the Nurburgring Nordschleife circuit where it was able to complete a lap in under eight minutes. The N400 package was available as either a coupé or Roadster with a total of 480 examples (240 Coupés, 240 Roadsters) being built, in note of the fact that there are 480 seconds in 8 minutes.

The motorsport-inspired V8 Vantage N420 came with the Sports Pack suspension as standard, a new sports exhaust system, and many carbon-fibre components which resulted in a weight saving over the standard car. In addition, the N420 has distinctive Aston Martin 'Race Collection' paint schemes available as an option although any other colour could be specified.

The engine is the same 4.7-litre
AJ37 V8 found in the base Vantage. The 4.7-litre V8 engine has been modified to deliver a peak power of at 7,300 rpm and torque of at 5,000 rpm representing an increase of 10 bhp and 20 Nm respectively. The modifications allowed for improved acceleration time of 0 to in 4.5 seconds and a top speed of for both the coupé and Roadster. Bushings, springs, and dampers were stiffened for the S model and the steering rack is quicker than in the base model. The aerodynamic enhancements include a deeper front bumper with carbon fibre splitter, larger side sills, a carbon fibre diffuser and a larger tailgate lip designed to sharpen the handling on the road. Additional visual differences include new wheels. A major difference in the Vantage S is the inclusion of the Sportshift II transmission, a 7-speed automated manual gearbox, as standard. The Sportshift II is lighter than the 6-speed Sportshift fitted on the standard Vantage. This contributes, along with other weight-saving parts, to a total vehicle kerb weight of . Later in 2013, a special model was unveiled named the SP10 as a celebration of Aston Martin's success in the Nürburgring 24-hour endurance race. Available as both in coupé and roadster body style, the SP10 features the same 4.7-litre V8 engine developing and of torque.
