The new front axle features a track width increased to 35-mm to reduce dynamic wheel load when cornering. A series of measures ensure substantially increased stability and precision in all driving scenarios. The new-design suspension at the front axle is 100% firmer, which makes for significantly improved steering precision. A further advantage becomes apparent when braking. The new suspension ensures instantaneous brake system response even under dynamic loads.

In combination with completely newly configured elasto-kinematics, the new wheel location provides greatly improved lateral dynamics and allows the driver of the C 63 AMG to benefit from significantly higher cornering speeds. A larger torsion bar stabiliser, new head bearings and dampers with rebound buffer springs further enhance this stability and precision. Steering feedback is also improved by the new kinematics. The speed-sensitive AMG sports steering has a ratio of 13.5:1, but feels more direct as a result of moving what is termed the instant centre of motion at the front axle. A more rigid Hardy disc in the steering column, as well as modified steering characteristics, make a further contribution to increased precision.

The multi-link independent rear suspension has also been thoroughly re-engineered, with a 12-mm-wider track and more camber leading to improved cornering performance. Reinforced drive shafts and drive joints increase fatigue strength and round off the improvements to the rear suspension of the C 63 AMG.

The completely newly developed AMG sports suspension combines outstanding handling dynamics with the long-distance comfort to be expected of a Mercedes – which also means that the C 63 AMG has the characteristic virtues of a genuine AMG.

The C 63 AMG is appropriately fitted with new 18-inch AMG light-alloy wheels in a five-spoke design. Painted in titanium grey, these high-gloss wheels in size 9.0 x 18 and 8.5 x 18 are fitted with wide-base tyres in size 235/40 R 18 (front) and 255/35 R 18 (rear). Even more dynamic handling is possible with the optionally available 19-inch AMG titanium grey light-alloy wheels in a multi-spoke design with a high-gloss finish. The front wheels are in size 8.0 x 19 with 235/35 tyres, with 9.0 x 19 wheels and 255/30 R 19 tyres at the rear.

Internally ventilated and perforated disc brakes all-round reside behind the spokes of the AMG wheels. The front brakes have 360 x 36 mm discs with six-piston fixed callipers, while 330 x 26 mm discs with four-piston fixed callipers handle deceleration at the rear. The AMG high-performance brake system is characterised by precisely metered braking, the shortest stopping distances and high fade resistance.

The Electronic Stability Program ESP® is specifically configured for the dynamic performance of the C 63 AMG, which is the first AMG model to feature 3-stage ESP® with a Sport function. This system offers three different control settings and is a logical further development of the AMG ESP® philosophy. The ESP® button in the centre console enables the driver to choose between three modes – "ESP ON", "ESP SPORT" and "ESP OFF" – the currently active mode is shown in the central display of the AMG instrument cluster.

In "ESP ON" mode, the onset of handling instability leads to braking intervention at one or more of the wheels, accompanied by a reduction in engine torque. Briefly pressing the ESP® button activates "ESP SPORT". In this mode the braking intervention to counter oversteer or understeer, as well as the accompanying reduction in engine torque, allows a higher dynamic threshold and, for instance, corresponding drift angles – which means that the driver of the C 63 AMG benefits from considerably more active driving pleasure. ESP® is restored to its normal function as soon as the brake pedal is operated.

Prolonged pressure on the ESP® button activates "ESP OFF". There is no intervention to control the handling dynamics and no reduction in engine torque – thus increasing driving enjoyment even further. "ESP OFF" should only be used by experienced drivers on dedicated racetracks. In this mode too, operating the brake pedal restores all the normal functions of ESP®.

The system's traction logic is active in all three ESP® modes. If one of the drive wheels threatens to spin, specific brake pressure is applied to virtually create the effect of a mechanical differential lock. This means that the engine power is transferred to the road even more effectively.

The AMG performance package and exclusive optional extras are available for the C 63 AMG. The components developed for the AMG PERFORMANCE STUDIO further enhance dynamic handling and are available for both the saloon and estate models.
