EBC 2020+ Audi RS6 4.0TT Rear Bluestuff Brake Pads

Track-Ready Rear Stopping Power for Audi RS Models

The EBC EBCDP52516NDX rear brake pad set uses the Bluestuff NDX compound to deliver race-level friction performance on the C8 Audi RS Q8, RS6 Avant, and RS7 Sportback while remaining R90 street-legal in Europe. Part No. DP52516NDX is a rear axle pad that fits the factory caliper positions on 2020-2026 RS Q8, 2021-2026 RS6 Avant in standard, GT, and Performance trim, and 2021-2026 RS7 Sportback in standard and Performance trim. Bluestuff NDX is a multi-layer compound that combines good cold bite with high-temperature resistance, delivering a friction coefficient in the 0.52 Mu range from normal street temperatures through track use. The compound generates noticeably less disc wear than most comparable race-oriented compounds, and the bedded surface produces low noise levels compared to full race pads at street speeds. EBC's Brake-In surface preparation treatment is applied at the factory so that the initial bedding period is shorter than with untreated pads, reducing the risk of cold pad glazing during the first few hundred miles of break-in use.

Key Features

FAQ

The EBCDP52516NDX is an EBC Bluestuff NDX rear brake pad set (EBC Part No. DP52516NDX) designed for the rear axle of the 2020-2026 Audi RS Q8, 2021-2026 RS6 Avant, and 2021-2026 RS7 Sportback C8-generation models, with R90 street homologation and a 0 to 550 degree Celsius operating range.

Yes. Bluestuff NDX is R90 approved for street use and delivers good cold bite from initial application. It is noisier and produces more dust than premium street pads, but it is designed to be driveable at street temperatures rather than requiring full heat before generating friction.

EBC applies the Brake-In surface treatment at the factory, which reduces the initial bedding requirement. EBC recommends performing 8 to 10 moderate stops from 30 mph during the first 200 miles to fully seat the compound against the rotor surface before using high-force braking.

This pad set fits the 2020-2026 Audi RS Q8 in all available trim configurations for those years on the rear axle position.

EBC offers matching Bluestuff NDX front pads for the C8 RS6 Avant platform. Search the EBC catalog by vehicle application or contact us to confirm the correct front pad part number for your specific model year.

Bluestuff NDX sits above Greenstuff and Redstuff in EBC's compound hierarchy. It operates at higher temperatures, delivers a higher friction coefficient, and is better suited for track use, while Greenstuff and Redstuff are optimized for lower-temperature street driving.

Yes. The 2024-2026 Audi RS7 Sportback Performance is a listed fitment for EBCDP52516NDX on the rear axle.

Bluestuff NDX pads work with standard cast iron and slotted or drilled rotors. EBC's GD series slotted rotors are commonly paired with Bluestuff NDX for track-oriented setups.

Install Instructions

1. Lift the vehicle safely and remove the rear wheels.
2. Remove the rear caliper from the caliper bracket without disconnecting the brake line and suspend it safely.
3. Slide out the worn pads from the caliper bracket and clean all contact surfaces with brake cleaner.
4. Inspect the rear rotors for minimum thickness, heat cracks, and scoring. Replace if below specification.
5. Retract the rear caliper pistons using the correct piston retraction tool for the Audi electronic parking brake system.
6. Apply thin brake lubricant to pad ears and caliper abutment surfaces only. Keep lubricant completely clear of friction material and rotor faces.
7. Install the new EBCDP52516NDX pads into the caliper bracket and confirm proper seating.
8. Reinstall the caliper and torque all bolts to Audi factory specification.
9. Reinstall wheels and lower the vehicle.
10. Pump the brake pedal until firm, then perform the EBC Brake-In bedding procedure.
