EBC Brakes for the Alfa Romeo Giulia: Which Parts Fit

By Core Brake Parts Tech Team — Circleville, OH warehouse

For the Alfa Romeo Giulia, EBC makes different parts for the 2.0-liter turbo cars and the 2.9-liter twin-turbo Quadrifoglio, and the two are not interchangeable. The 2.0T takes the DP52325NDX Bluestuff front pad and the DP22315, DP32315C and DP42315R rear pads, plus the USR2130 slotted front rotors. The Quadrifoglio takes the DP52354NDX Bluestuff and DP42354R Yellowstuff front pads. On a car with carbon ceramic brakes, don't install anything until you've read the carbon ceramic section below.

This guide covers each EBC part we carry for the Giulia, which engine it fits, how the compounds differ, and what to know about the electronic parking brake before you start on the rear.

First, identify which Giulia brake system you have

Every Giulia brake part in our catalog lists the engine it was built for. That is the first thing to check, because the 2.0T and the Quadrifoglio use different front pad shapes. Look at the engine on your registration or window sticker: 2.0L turbo four-cylinder (Base, Ti, Sport and similar trims) or 2.9L twin-turbo V6 (Quadrifoglio).

Next, check whether a Quadrifoglio has iron rotors or the optional carbon ceramic matrix brakes. The difference matters. EBC pads are designed to run on iron rotors, and the carbon ceramic cars have their own recall history (covered below). If you're not sure, a dealer can decode the brake option from your VIN.

EBC pads for the Giulia 2.0 Turbo

At the front of a 2.0T, the EBC Bluestuff NDX DP52325NDX front pads for the Giulia 2.0 Turbo are EBC's highest-friction option. EBC lists Bluestuff NDX at a 0.52 friction coefficient with an operating range from ambient up to 550 C (1000 F). EBC says the pad beds in quickly on the street with no noise, squeal or vibration, and it is the compound EBC now recommends for track days. EBC expects 20,000 miles or more of street use and says to replace the pads at 3 mm (1/8 inch) of friction material.

At the rear, the 2.0T has three EBC compounds to choose from:

• Redstuff ceramic rear pads (DP32315C): EBC's low dust street pad. EBC claims 60 to 90 percent less dust, lists a 0.5 nominal friction coefficient, and says it is not a track pad. EBC also notes Redstuff needs 500 to 1,000 miles to reach full performance.
• Greenstuff 2000 rear pads (DP22315): a medium to low dust street compound. EBC rates it at a nominal 10 to 15 percent brake improvement over stock and a 0.55 nominal friction coefficient, and says it is ECE R90 approved.
• Yellowstuff rear pads (DP42315R): built for fast street driving, with strong cold bite. EBC gives a green fade threshold of 400 C (750 F). Since its copper-free reformulation, EBC points track drivers to Bluestuff instead.

Pick the rear compound to suit the front. If you run Bluestuff NDX up front for track days, a Yellowstuff rear is the more consistent pairing. For a daily driver, Redstuff or Greenstuff keeps dust and noise down. Mixing a race-oriented front with a mild rear changes how the brakes feel.

EBC pads for the Giulia Quadrifoglio

The 2.9L twin-turbo Quadrifoglio uses a larger front pad, and EBC makes two compounds for it:

• EBC Bluestuff NDX DP52354NDX front pads for the Giulia Quadrifoglio, for owners who drive hard on the street or go to track days.
• EBC Yellowstuff DP42354R front pads for the Quadrifoglio, for fast road use with good cold bite and less track focus.

Both pads are for iron rotors. Given how much power the Quadrifoglio makes, the track versus street decision matters more here than on the 2.0T. Once rotor temperatures go past what a street compound is designed for, it will fade. EBC puts Yellowstuff's fade threshold at 400 C and says track use usually runs hotter than 500 to 600 C.

Rotors: EBC USR for the 2.0T, GiroDisc for the Quadrifoglio

For 2017 and newer Giulias, the EBC USR2130 slotted front rotors are EBC's premium quiet street rotor. EBC machines them from R90-approved G3000 grey iron, uses a narrow multi-slot pattern to keep air noise down, and finishes them with a black anti-rust coating. EBC says the slots help pads wear flat and parallel instead of developing ridges, and that the rotors perform best alongside Redstuff, Greenstuff or Yellowstuff pads.

EBC is clear that slotted rotors on their own do not add stopping power. The gain comes from a matched pad and rotor set. That is also why new pads should go on flat rotors: EBC says bedding Bluestuff on off-flat or grooved rotors can take three times as long.

Quadrifoglio owners replacing iron rotors can use GiroDisc two-piece rotors. The GiroDisc A1-224 front set and A2-224 rear set are for iron-rotor cars. GiroDisc builds them with a cast iron ring on a 6061-T6 aluminum hat, joined by floating drive pins, and says they bolt on with the factory calipers. For cars that came with carbon ceramic brakes, the GiroDisc A2-209 rear rotors replace the ceramic discs with iron ones. Check the listing to confirm which system each part is for. You can also browse all brake rotors and brake pads.

Carbon ceramic recall and the brake pedal recall

Two Giulia brake recalls are worth checking before you work on the car:

• NHTSA 23V382000 (2017 to 2020 Giulia with carbon ceramic matrix brakes): in some driving maneuvers the brake system could apply too much clamp force and crack a rotor. Dealers update the brake system module software for free.
• NHTSA 24V943000 (2019 to 2020 Giulia): the fastener joining the brake pedal to the brake booster may have been assembled incorrectly, which could let the pedal separate from the booster. Dealers inspect and repair the connection for free.

Enter your VIN on nhtsa.gov or ask any Alfa Romeo dealer to see whether either campaign is still open on your car.

Rear pads and the electronic parking brake

On the 2.0T, the rear calipers have motor-driven electronic parking brake actuators. You cannot push the rear pistons back like an ordinary caliper. Put the car in Brake Service Mode from the infotainment settings first so the system retracts the motors; you will hear them wind back. Then remove the calipers and press each piston straight in with a spreader. Service guides warn against forcing a piston while the actuator is clamped, because that can strip the actuator gears and ruin the caliper.

After the new pads are in, exit service mode, cycle the parking brake switch while the car is stopped, and bed the pads in. EBC's street bed-in for Bluestuff is about 200 miles of gentle braking, building up gradually. Redstuff needs longer, as noted above. Tighten caliper and wheel fasteners to the values in the factory service manual. If a caliper is seized or leaking, see our brake calipers collection, and consider fresh brake hardware while the car is apart.

A front pad and rotor job on the Giulia is a reasonable DIY with basic tools. The rear pads take a bit more care because of the parking brake, and anyone with carbon ceramic brakes should leave that system to a specialist.

Frequently Asked Questions

Do the Giulia 2.0T and Quadrifoglio use the same EBC front pads?

No. The 2.0T uses DP52325NDX and the 2.9L twin-turbo Quadrifoglio uses DP52354NDX or DP42354R. Match the engine in the listing to your car.

Which EBC pad has the least dust for a daily-driven Giulia?

Redstuff. EBC says it cuts dust by 60 to 90 percent. It is a street-only pad and needs several hundred miles to fully bed in.

Can I use Bluestuff NDX on the street?

Yes. EBC calls it a super-street and track day pad that beds in quickly with no noise, squeal or vibration. It has more bite than a stock pad, which some drivers like and others don't.

Can I put EBC pads on carbon ceramic rotors?

The EBC pads covered here are for iron rotors. If your Quadrifoglio has carbon ceramic brakes, either use the pads the factory specifies or convert to iron rotors with a kit such as GiroDisc before switching to iron-rotor pads.

Why won't my rear caliper piston push back?

The electronic parking brake actuator is holding it. Put the car in Brake Service Mode so the motors retract, then press the piston straight back. Do not force it.
