What if you could transform your Mercedes C63 AMG from a powerful yet unpredictable beast into a controlled, high-performance machine that grips the road like never before? At Regal Autosport in Southampton, we specialise in upgrades that make a real difference, none more so than the Wavetrac Limited Slip Differential (LSD). This essential modification dramatically enhances traction, stability, and control, unlocking the true potential of your C63 AMG.
Why Upgrade to a Wavetrac LSD?
Most C63 AMG models from the factory were not equipped with a limited slip differential (LSD), meaning they come with an open differential that severely limits performance. An open differential has a torque bias ratio of 1:1, meaning when one wheel starts to slip, the opposing wheel can only receive the same limited amount of torque as there is traction at the wheel with the least grip, leading to instability and a loss of control.
By contrast, the Wavetrac LSD increases the torque bias ratio to 4.5:1, ensuring that the wheel with more grip can receive significantly more torque. The result? A complete transformation of the C63 AMG's handling and power delivery.
Unexpected Discovery: The Quaife Differential
When we removed the factory differential from this particular C63 AMG, we were surprised to find that it already had a Quaife LSD installed. However, the customer still wanted an upgrade, citing that ‘the car didn't feel like it has an LSD' highlighting the performance limitations of the Quaife differential and other Automatic Torque Biasing (ATB) LSDs.
Most ATB differentials struggle when axle load is reduced—essentially behaving like an open differential under certain conditions. The Wavetrac overcomes this limitation thanks to its innovative wave hub cam device, which internally creates load to maintain power biasing across the axle. This ensures consistent performance in all driving conditions, unlike other ATB LSDs.
Additionally, the carbon fibre bias plates inside the Wavetrac ensure consistent friction levels throughout the lifetime of the differential, delivering long-term reliability and peak performance.
Social Media Reactions: What the Community Had to Say
This discovery sparked a lively discussion on Instagram, with enthusiasts sharing their thoughts:
💬 "Absolutely wild that this customer didn’t even realise he had an LSD fitted 🥵" – @aashstewart
💬 "It’s a ‘507 Edition’ which comes with the Driving Package (including an LSD, higher top speed, etc.). Car didn’t feel like it had an LSD fitted??? The only way to find out was to take it apart to check. Believe me, the new Wavetrac Upgrade was well worth it & makes the car feel/drive much better!! 💯" – @507amgc63
💬 "This is one of the best upgrades for a C63, 100%" – @7.nth
💬 "Well done Team Regal 👏🏽👏🏽" – @507amgc63
💬 "No disrespect, if owner didn’t realise he had a Quaife, he ain’t gonna notice any change with a Wavetrac either… 🙄" – @c63.boon
💬 "I have noticed the difference. Easier to control the back end & the wheels hunker down when you floor it!!! 💣" – @507amgc63
💬 "By the way, I know my car fairly well as I have owned it since 2017. I have covered many miles in it, including nearly 2,000 miles on an NC500 trip to Scotland 🏴 on THE Very Best Roads… 😮" – @507amgc63
These conversations reinforce just how transformative the Wavetrac LSD upgrade is, even for cars that technically already have an LSD installed!
Enhanced Sound and Performance with a Secondary Cat Delete
Alongside the LSD upgrade, we also performed a secondary cat delete, which significantly enhances the exhaust sound, improves the power delivery, and enables quicker gear shifts. The end result? A more engaging and thrilling driving experience.
Customer Feedback: A 500+ Mile Trip Well Worth It
Our customer drove over 500 miles round trip for this upgrade, and their feedback speaks volumes:
"Well worth the 500+ mile round trip, although I wasn’t looking forward to it at the start. Left my Mercedes 507 C63 AMG 6.2 litre with Regal for 2 days. Staff were really friendly, professional, and know what they are talking about.”
“Had the Wavetrac LSD fitted, which is an upgrade to the Quaife that was currently on there. Felt the difference straight away—the back wheels seem to hunker down slightly when putting your foot down. It distributes the power more evenly, so the back end is much easier to control.”
“Also had a Secondary Cat Delete Mid Pipe fitted, which gives more power, quicker gear shifts, and a much louder sound! 💣🔥 The money spent will give me plenty more smiles… 😊"
Conclusion: The Best Differential Upgrade for the C63 AMG
If you're looking to maximise traction, improve stability, and unleash the full potential of your Mercedes C63 AMG, the Wavetrac LSD is the ultimate upgrade. Combined with a secondary cat delete, your car will not only handle better but also sound more aggressive and perform at its peak.

Traction and Differential FAQs
What are traction conditions, and how do they affect my driving?
At Regal Autosport, we understand that traction conditions can vary widely, from dry asphalt to wet and icy roads. These conditions directly influence how well your vehicle grips the road, affecting safety and performance.
How does traction control work with an upgraded differential?
Traction control with an upgraded differential like a Quaife or Wavetrac helps manage applied torque load effectively. This ensures stability by minimising wheel slip during acceleration and at sharp corners.
What happens when the differential shifts power?
When the differential shifts power, it redistributes the engine’s torque between the wheels based on which one has the most grip. This process is crucial for maintaining control in varying torque situations and can make a massive difference in performance.
Why is choosing the proper unit important for my performance package?
Selecting the proper unit for your performance package is vital because it ensures the resistive torque is optimally managed. This process maximises your car's efficiency and effectiveness on the road, especially under high load conditions.
Can an electronic differential handle differences in axle speed?
Yes, an electronic differential can effectively handle differences in axle speed by adjusting the clutch plates to redistribute torque to the wheel with better traction. This adjustment helps maintain control and minimises tyre slip in diverse driving conditions. Discover how this technology can enhance your driving experience.
