EBC Racing 2016+ Dodge Charger SRT Hellcat 6.2 Supercharged SG Series One Piece Rear Rotor Set

Swept Groove Slotted Rear Rotors Engineered for the 707hp and 797hp Hellcat BREMBO Rear Caliper Package

The EBC SG7366 is a pair of SG Series swept groove slotted vented rear brake rotors purpose-built for the 2015-2021 Dodge Challenger SRT Hellcat, 2018 Challenger SRT Demon, 2018-2021 Challenger SRT Hellcat Widebody, 2016-2020 Dodge Charger SRT Hellcat, and 2020 Charger SRT Hellcat Widebody. The SG7366 uses EBC's swept groove slot pattern cut at an angle across the rotor face, which continuously cleans and abrades the pad surface to remove glazing and embedded gas, maintaining consistent bite throughout a braking event. At 350mm diameter and 28mm nominal thickness, these are sized to the exact OEM specification for the Brembo rear caliper package fitted to these models. The rotor body is cast from high-carbon iron to G3000 specification, which EBC validates is a harder and more crack-resistant alloy than standard gray iron commonly used in economy replacement rotors. Every SG7366 is 100% run-out inspected on EBC's dynamometer before leaving the factory to verify zero lateral distortion before the rotor ever reaches a vehicle.

Key Features

• Swept groove slot pattern removes brake dust, gas, and pad glazing continuously for consistent bite during hard stops
• 350mm diameter, 28mm nominal thickness matched to OEM Brembo rear caliper specification on Hellcat and Demon models
• High-carbon cast iron to G3000 specification for superior crack and warp resistance versus standard gray iron
• Vented one-piece rotor construction with wider cooling vanes than OEM for improved thermal capacity
• Gray coated non-rotor surfaces for corrosion resistance on hat, hub face, and vane edges
• 115mm center bore for direct hub-centric fit on Dodge Challenger and Charger platforms
• 100% run-out inspected at the factory to guarantee zero distortion and vibration-free pedal feel
• Sold as a set of 2 rear rotors

About EBC Brakes

EBC Brakes is a UK-founded, globally operating brake manufacturer that has produced friction and rotor products since 1983. EBC operates eight dynamometer systems across two factory locations and invests continuously in friction material development, rotor metallurgy, and quality control infrastructure. The SG Series rotors are EBC's swept groove slotted product line for street and light track use, positioned between the plain OE-replacement GD Series and the full two-piece race rotor designs. EBC manufactures all SG Series rotors to meet or exceed OEM dimensional and metallurgical specifications and backs each rotor with a 12-month or 12,000-mile warranty against manufacturing defects.

Frequently Asked Questions

A standard OEM-replacement rotor is a smooth-face vented iron casting. The SG7366 adds EBC's swept groove slot pattern, which is machined into the rotor face at an angle. These slots perform two functions: they vent gases that build up between the pad and rotor during heavy braking (which causes fade), and they continuously scrub and resurface the pad face to remove glazing. The SG7366 also uses a higher-carbon iron alloy than typical economy rotors, providing better crack resistance under the extreme thermal cycling of a 707 to 797 horsepower vehicle.

No. The SG7366 is a direct bolt-on replacement for the rear rotors on equipped Challenger SRT Hellcat, Demon, Widebody, and Charger SRT Hellcat variants. It uses the same 350mm diameter, 5-lug pattern, 115mm center bore, and 28mm nominal thickness as the factory Brembo rear rotor, so all factory hardware, caliper brackets, and splash shields install without modification. No adapter plates or custom hardware are required.

EBC recommends pairing SG Series slotted rotors with their Yellowstuff (DP41xx) pads for aggressive street and occasional track duty, or Bluestuff (DP51xx) pads for track-focused driving with street registration. Redstuff (DP31xx) pads are EBC's low-dust option for primarily street use. Avoid running OEM-style economy pads against slotted rotors, as the slot edges can accelerate wear on softer pad compounds not designed to interface with a grooved surface.

Yes. Proper bedding is essential. EBC recommends performing 8 to 10 moderate stops from approximately 35 mph, allowing the rotor to cool between each stop, followed by 8 to 10 more aggressive stops from 55 mph. This procedure transfers a thin, even layer of pad material onto the rotor face and ensures the pad resin is fully cured. Skipping the bedding process can result in uneven pad deposits on the rotor face, which causes vibration and pulsation under braking.

EBC SG Series swept groove rotors are typically non-directional, meaning either rotor can be installed on either side of the rear axle. Confirm this for your specific application by checking the EBC instruction sheet included in the box before installation. If the slots are curved or angled in a specific direction that requires matched left and right fitment, this will be noted on the packaging and installation guide.

Slotted rotors like the SG7366 are generally considered more durable than drilled rotors for high-power street applications. Cross-drilled holes create stress concentration points in the iron casting, which can lead to cracking under the extreme thermal cycling produced by repeated hard stops from high speeds. Slots do not create the same stress risers and perform equivalent or better gas venting. For a daily-driven or weekend performance Hellcat, slotted SG7366 rotors are a more durable choice than cross-drilled alternatives.

EBC backs the SG7366 with a 12-month or 12,000-mile warranty against manufacturing defects including casting porosity, premature cracking, and dimensional errors. Warranty does not cover normal wear, surface rust on vane edges or non-swept areas (which is cosmetic on a vented rotor), or damage caused by improper installation, overheating beyond design limits, or use of incompatible brake fluid.

The SG Series is EBC's performance street rotor, suitable for spirited street driving, autocross, and light track duty. For sustained high-speed track sessions where brake temperatures routinely exceed 700 to 800 degrees Celsius, EBC recommends stepping up to their two-piece floating racing rotors designed for the Hellcat platform and pairing them with full race pad compounds such as EBC's RP-1 or Bluestuff NDX. For occasional track day use in the hands of a novice or intermediate driver, the SG7366 with Yellowstuff pads is a capable and cost-effective setup.

Installation Instructions

1. Safely lift and support the vehicle on jack stands. Remove the rear wheels to access the brake assembly.
2. Using a C-clamp or piston reset tool, compress the rear caliper pistons fully into the caliper body. Check that the brake fluid reservoir does not overflow when compressing; remove fluid if necessary before compressing.
3. Remove the caliper mounting bolts and hang the caliper from a wire hook or bungee cord. Do not allow it to hang from the brake hose.
4. Slide the old rotor off the hub. If it is stuck, strike the hat area between the lugs with a rubber mallet to break the rust bond.
5. Clean the hub mounting surface with a wire brush and brake parts cleaner to remove all rust scale and debris. A clean hub surface is essential to prevent rotor runout.
6. Mount the new SG7366 rotor onto the hub. Install one or two lug nuts by hand to hold the rotor flat against the hub during caliper reinstallation.
7. Reinstall the caliper over the new rotor and torque the caliper mounting bolts to the OEM specification (refer to service manual for your specific year and model).
8. Reinstall the wheel and torque the lug nuts to 110 ft-lbs in a star pattern.
9. Lower the vehicle and pump the brake pedal until firm pedal pressure is restored and the pads contact the new rotor face.
10. Perform the EBC bedding procedure: 8 to 10 moderate stops from 35 mph, cool, then 8 to 10 more aggressive stops from 55 mph. Allow the brakes to cool completely before storing or driving normally.
