Mercedes-AMG C63S (W205): Ultimate Drivetrain Upgrades by Hardeman Motorsport

At Hardeman Motorsport, we are deeply rooted in the world of AMG performance. The C63S with its powerful V8 biturbo places high demands on the rear axle. We offer proven solutions to get this power to the asphalt efficiently and reliably.

Reinforced Rear Differential & Sper-conversion

Although the C63S is equipped with an electronic limited slip differential as standard, it often falls short with increased power or sporting use. We build differentials that are ready for the real thing:

• Mechanical limited slip conversion (OS Giken / Drexler style): For more predictable drifting, maximum traction out of corners and superior durability compared to the standard e-diff.
• Reinforced gears: Specially treated to cope with the huge torque peaks of tuned M177 engines.
• Repair of e-diff: We see a lot of damage to the small gears in the reverse gear and wear on the reverse clutch. We can repair, replace and return these to factory specification for original optimum handling and a relatively inexpensive repair.
