Vehicle Fitment

• 2017-2023 Audi Q7 (Premium, Premium Plus, Prestige - 2.0L TFSI I4 & 3.0L TFSI V6) - Front
• 2018-2023 Audi S4 (Premium, Premium Plus, Prestige - 3.0L TFSI V6) - Front
• 2017 Audi S5 (Base - 3.0L TFSI V6) - Front
• 2018-2023 Audi S5 (Premium Plus, Prestige - 3.0L TFSI V6; 2019-2023 Premium - 3.0L TFSI V6) - Front
• 2018-2023 Audi SQ5 (Premium, Premium Plus, Prestige - 3.0L TFSI V6) - Front

Fitment Notes

• Front axle fitment only - sold as a pair of front rotors; rear applications require separate EBC part numbers
• FMSI Pad No. D1894 - verify pad FMSI number before ordering; EBC recommends pairing GD series rotors with matched EBC brake pads for optimal performance and warranty coverage. Compatible EBC pad compounds include Greenstuff 6000/7000, Yellowstuff, and Redstuff
• Fits both the 2.0L TFSI four-cylinder and 3.0L TFSI V6 variants of the Q7, as all Q7 4M-generation models share the same 349mm front rotor specification regardless of engine
• The S4, S5, and SQ5 listed all use the Audi 3.0L TFSI V6 with the same 349mm front brake specification - verify your model year and trim before ordering
• These rotors are directional - wide-aperture slots and dimple pattern must point toward the rear of the vehicle when installed; confirm left/right orientation before fitting
• Silver GEOMET anti-corrosion coating does not require removal before installation - it will naturally wear off in the pad contact area within the first 10-20 stops; do not use brake cleaner or solvents to remove it, as this may void the EBC warranty
• Minimum rotor thickness: 32mm - do not continue use if rotors wear below this threshold
• Do not fit upgrade pads to the rear unless the same or equivalent performance compound is fitted to the front

Features

• EBC 3GD Series wide-aperture slotted and dimpled design - full-sweep scraper slots running edge-to-edge across the 349mm braking surface combined with blind-drilled surface dimples, delivering active pad degassing and continuous thermal evacuation without the structural risk of through-drilled rotors
• Wide-aperture full-sweep slots - continuously sweep the entire pad contact zone on every wheel revolution, expelling brake dust, debris, gases, and water from the pad/rotor interface; validated in ECE R90 testing to run up to 100°F cooler than plain non-slotted rotors under equivalent braking loads
• Blind-drilled surface dimples - EBC's patented design provides pad gas venting and additional surface cooling without the stress concentration points that initiate thermal cracking in through-drilled rotors; particularly important on the heavier Q7 platform under sustained braking loads
• Full-sweep slot pattern maintains flat and parallel pad wear throughout pad life - prevents the uneven glazing and pad cracking common with plain rotors during sustained hard braking on performance-oriented B9-platform Audis
• Precision-machined from high-quality G3000 OE-spec grey cast iron - machined to OE specifications for thermal capacity, crack resistance, and hardness; 100% individually runout-inspected and balanced before release; British-made
• Silver GEOMET anti-corrosion finish - applied to all non-braking surfaces for long-term corrosion resistance, maintaining clean rotor hub appearance consistent with OE silver-finish rotors on these Audi platforms
• ECE R90 European brake safety legislation compliant - independently stress-tested and validated for safety and durability under aggressive braking conditions
• Vented internal construction - internal vane channels direct airflow through the 34mm-thick rotor body as the wheel rotates, providing continuous background cooling between brake applications during spirited driving or sustained highway braking
• Direct OE-replacement fitment - bolt-on installation with no caliper, bracket, or brake line modifications required for any supported Audi application
• Country of Origin: Great Britain

Product Description

The EBC GD2150 is a 3GD Series slotted and dimpled sport front brake rotor designed as a direct OE-replacement performance upgrade for the 349mm front brake application shared across the second-generation Audi Q7 (4M, 2017-2023), the B9-generation Audi S4 (2018-2023), the B9-generation Audi S5 (2017-2023), and the B9-generation Audi SQ5 (2018-2023). These are all MLB-platform Audi vehicles sharing a common 349x34mm vented five-bolt front rotor specification - spanning everything from the everyday luxury Q7 SUV through the performance-focused S4 and S5 saloon and coupe to the SQ5 performance crossover - and the GD2150 fits all of them with a bolt-on, zero-modification installation. The 349mm diameter is a large front disc by sports/luxury sedan standards, and the 34mm braking width gives the rotor significant thermal mass for sustained heat absorption. However, the plain OE-style surface of the stock rotor leaves boundary gas management and debris evacuation entirely to pad design, which under sustained hard driving - extended autobahn runs, mountain passes, or repeated high-speed stops - allows the gas and dust layer between pad and rotor to build to levels that produce brake fade and softened pedal feel.

The GD2150 addresses this through EBC's established 3GD geometry: wide-aperture full-sweep scraper slots that run the full width of the 349mm braking surface, sweeping the pad contact zone clean on every wheel revolution and continuously removing the boundary layer before it can insulate the pad from the rotor surface. The blind-drilled surface dimples add a second degassing mechanism, allowing gas to escape directly from the pad face rather than being trapped at the interface. Both features operate simultaneously on every stop without driver input, and the combination actively maintains the consistent, firm bite that high-output Audi drivers expect from the front axle through demanding braking events. The 34mm vented casting adds a third thermal management layer - centrifugal airflow through the internal vane passages continuously extracts heat from the rotor body between brake applications, helping the system recover thermal capacity faster than a plain rotor of equivalent mass. The result is measurably cooler brake temperatures across a sustained braking session, which directly translates to more consistent pad friction, reduced fade, and longer pad and rotor service life.

All supported vehicles share the same 349mm front rotor specification regardless of engine variant - the Q7 2.0T and Q7 3.0T both use this disc, as do the S4, S5, and SQ5 3.0T models - making the GD2150 a single-part-number solution across a wide range of performance and luxury Audis from the 2017-2023 period. Installation is a standard front rotor swap in approximately 30-60 minutes per side with basic shop tools. The silver GEOMET anti-corrosion coating on non-swept surfaces wears naturally from the pad contact band within the first 10-20 stops and must not be disturbed with solvents prior to installation. A bedding-in sequence of 10-15 progressive stops from increasing speeds after fitting is strongly recommended to transfer a uniform layer of pad material onto the fresh rotor surface, maximising long-term bite and minimising initial bedding noise. EBC recommends pairing the GD2150 with matched EBC brake pads using FMSI D1894 - including Greenstuff 6000/7000 for daily driving, Redstuff for performance street use, and Yellowstuff for the highest demands - for thermal compatibility and full warranty coverage.
