Mercedes GLE 63S rear axle upgrade: Audi RS Q8 ceramic brakes with Epytec adapter
Introduction & aim of the conversion
The Mercedes-Benz GLE 63S (W166 & C167) is a powerful SUV with impressive performance. Nevertheless, there is potential for optimisation in the braking system - especially on the rear axle. Our customer wanted significantly improved braking performance and a stable ceramic solution without compromising on the handbrake.
We therefore decided to upgrade to the Audi RS Q8 ceramic brake disc with a diameter of 370 mm (OE number 4M0 615 601 AD) in combination with the original RS Q8 ceramic handbrake calliper. To adapt these components perfectly to the axle mount of the GLE 63S, we developed a customised Epytec brake calliper adapter made of high-strength steel with galvanised blue zinc plating.
Technical details of the upgrade
In order to install the RS Q8 ceramic brake system on the rear axle of the GLE 63S, a specially developed Epytec brake calliper adapter was required. This adapter was manufactured from high-strength steel and then galvanised blue to ensure maximum corrosion resistance and durability.
Components used:
✅ Audi RS Q8 Ceramic brake disc (370 mm, OE-number 4M0 615 601 AD)
✅ Audi RS Q8 Handbrake caliper for the ceramic brake disc ( brake caliper: 4M8615403AQC8 / 4M8 615 403 A QC8 brake carrier: 4M8 615 425 QC8)
✅ Specially manufactured Epytec brake caliper adapter made from high-strength steel
✅ Surface galvanised blue for optimum corrosion protection
✅ Material certificate for the adapter for easy registration
This combination gives the GLE 63S an enormous increase in braking power at the rear axle - with the proven performance of an Audi RS Q8 ceramic brake.
Our solution: Prototyping at Epytec
Our customer sent us the required components so that we could carry out the prototyping in our workshop. Based on the original parts, we developed a perfectly fitting adapter that adapts the RS Q8 ceramic brake and the handbrake caliper exactly to the axle mount of the GLE 63S.
Thanks to our experience in the manufacture of tuning adapters, we were able to ensure the optimum positioning of the brake calipers so that the disc runs in the centre of the caliper and the handbrake works perfectly.
It goes without saying that our customers receive a material certificate, which enables problem-free registration with the TÜV.

🔹 Improved controllability of the braking force
🔹 Optimum heat dissipation, ideal for sporty driving styles
🔹 Compatibility with the electronic parking brake of the GLE 63S
The customer is absolutely satisfied with the upgrade and delighted with the increase in performance.

The brake system is registered via individual approval. We supply a material certificate for the tuning adapters to enable easy registration. Our tuning adapters are manufactured with the highest precision and comply with TÜV specifications.
Conclusion & added customer value
This upgrade makes it possible to integrate the superior braking performance of the Audi RS Q8 into the Mercedes GLE 63S. Thanks to our customised adapter, the complete RS Q8 ceramic brakes can be used on the rear axle - including the handbrake. The result: more safety, better deceleration and a first-class look.
