Aston Martin DB9 Brake Upgrades: Wilwood vs EBC Kits

Upgrading the brakes on your Aston Martin DB9 is one of the most rewarding modifications you can make to a 444-to-510 hp, roughly 3,900-pound V12 grand tourer built to cross continents at triple-digit speeds. The best Aston Martin DB9 brake upgrades fall into three tiers: a full two-piece big-brake rotor kit for track use, a matched pad-and-rotor kit for fast-road driving, and a simple pad swap for better bite and less dust on the street. In this comparison we put the $2,908 Wilwood ProMatrix rotor kit head-to-head with EBC’s S5 and S6 kits and standalone Bluestuff, Yellowstuff and Redstuff pads, so you can match the right hardware to how you actually drive your 2004–2016 DB9.

Why brakes are the first upgrade for a DB9

Brakes are the highest-value upgrade on any Aston Martin DB9 because the car asks so much of them. The 5.9-liter (5,935 cc) naturally aspirated V12 made 444 hp at launch in 2004 and climbed to 510 hp on the 2013 facelift, pushing a grand tourer that weighs roughly 3,900 pounds to a top speed near 186 mph. All of that kinetic energy becomes heat every time you slow down, and heat is what makes stock brakes fade, warp rotors and glaze pads after a few hard stops.

The DB9 left the factory with large ventilated steel discs and, on many cars, soft OE pad compounds tuned for quiet, low-effort street driving. That combination is fine for a Sunday cruise, but it runs out of thermal headroom quickly on a mountain descent or a track lapping day. Upgrading the friction material and, where the budget allows, the rotors themselves raises the temperature the system can shrug off before performance drops — which is exactly why brakes, not power, are where most DB9 owners should spend first.

There are three practical paths. A two-piece big-brake rotor kit like the Wilwood ProMatrix adds thermal mass and drilled, curved-vane cooling while keeping your factory calipers. A matched pad-and-rotor kit such as EBC’s S5 or S6 pairs sport rotors with a specific pad compound for a bolt-on jump in bite. And the simplest option, a performance pad swap, changes the friction compound alone. The table below shows how each stacks up on the DB9.

Here are the five most relevant DB9 (2004–2016, 5.9L V12) brake upgrades we stock, ranked by capability and price. All prices are current at NLP Performance in Tampa, FL.

Wilwood ProMatrix rotor kit: the track answer

The Wilwood ProMatrix front-and-rear rotor kit is the most capable brake upgrade you can bolt to a DB9 without replacing the factory calipers. It swaps the one-piece OE discs for two-piece assemblies: a lightweight aluminum hat mated to a Wilwood GT 72-vane (front) and 32-vane (rear) curved-vane rotor cast from proprietary Spec-37 iron alloy. Curved internal vanes pump air through the rotor far more effectively than the DB9’s straight-vane OE discs, and the Spec-37 alloy is formulated specifically to resist cracking and distortion at the extreme temperatures of repeated high-speed stops.

EBC S6 vs S5 kit: bolt-on pad-and-rotor value

If a big-brake kit is more than you need, EBC’s pre-matched S-series kits are the smart middle ground. Both pair EBC GD Sport front rotors — dimpled and slotted for gas venting and cleaner pad bite — with a specific pad compound, and both bundle the pads, rotors and caliper lube together to save about 15% over buying the parts separately. The only real difference is the pad: the S6 kit uses Bluestuff NDX, while the S5 kit uses Yellowstuff.

Which one should you buy? Choose the S6 kit ($564.22) if you do occasional track days or aggressive canyon runs — Bluestuff NDX is a high-friction sport-and-race compound with the highest bite of EBC’s street-legal range. Choose the S5 kit ($544.07) for spirited road use; its GG-rated Yellowstuff pads work from cold with no warm-up and handle both street and light track, making them the more forgiving daily-plus-weekend choice. Both bolt to the DB9’s factory front calipers.

EBC pad compounds: Bluestuff, Yellowstuff and Redstuff

The most affordable DB9 brake upgrade is a pad swap on your existing rotors. EBC offers three front-pad compounds for the 5.9L DB9, each tuned for a different driver. Picking the right one comes down to how hot you get the brakes and how much dust you can tolerate on the wheels.

EBC Bluestuff NDX — the track-focused pad

Bluestuff NDX ($221.75) is EBC’s highest-bite street-legal compound and the pad inside the S6 kit. It is a high-friction sport-and-race material proven on track with quality calipers, yet it remains streetable for the drive home. Choose Bluestuff if you run track days or want the most aggressive bite available without going to a full race pad.

EBC Yellowstuff — street and track in one pad

Yellowstuff ($201.60) is an aramid-fiber compound and one of the first pads engineered for both street and track. It delivers high brake effect from cold with no warm-up, then gets stronger as temperatures climb under hard driving. It is not a low-dust pad, so if clean wheels matter most, look at Redstuff instead. Yellowstuff is the same compound used in the S5 kit above.

EBC Redstuff — the low-dust daily driver

Redstuff ($201.60) is the pad for owners who want a cleaner wheel and quiet, refined street manners. EBC rates it as their lowest-dust pad, cutting brake dust by roughly 60–90% versus a typical performance pad, and the little dust it does produce wipes off easily. It is the right pick for a DB9 that lives on the road and rarely sees a track.

Prefer an OE-style street pad? Consider Hawk HPS

Not every DB9 owner wants a performance compound. Hawk’s Light Truck & SUV (LTS) / High Performance Street pad ($127.00) is the most affordable upgrade here and targets a quieter, OE-like feel with more stopping power than a worn factory pad. It is a sensible replacement-plus-upgrade for early cars and shares its shape with the 2006–2008 V8 Vantage, but for repeated hard stops the EBC compounds above have more thermal headroom.

How to choose the right DB9 brake upgrade

Match the hardware to how you drive. If you track your DB9 or want the biggest jump in fade resistance, the Wilwood ProMatrix rotor kit is the clear top pick because it upgrades the rotors themselves, front and rear, while keeping your factory calipers. If you want a straightforward bolt-on that pairs new sport rotors with a matched pad, the EBC S6 kit (track-leaning) or S5 kit (road-leaning) delivers most of the benefit for well under $600. And if your rotors are still healthy and you simply want better bite or less dust, a set of EBC Bluestuff, Yellowstuff or Redstuff pads is the fastest, cheapest way to transform the pedal.
