Hellcat Rotors and Brakes: 2-Piece vs OEM for Track and Street
The Hellcat Braking Problem: Power Without Proportional Stopping
Dodge built the Hellcat to dominate straight-line speed. Factory brakes were engineered to pass federal safety standards and keep dealer service costs predictable — not to survive repeated deceleration from triple-digit speeds. The result is a car that can run 10-second quarter miles on stock tires but leaves owners searching for Hellcat rotors and Hellcat brakes upgrades within the first year of ownership.
The symptoms are consistent across Challenger Hellcat, Charger Hellcat, Redeye, and Super Stock owners: pedal pulsation after a spirited drive, blue rotor faces, brake fade on the third or fourth hard stop, and rotor replacement intervals measured in months instead of years. The root cause is thermal management — OEM G3000 single-piece rotors cannot shed heat fast enough for a 4,400-pound, 700+ HP platform.
Hellcat Rotors: Front G3500 2-Piece, Rear G11H18 1-Piece
Factory Hellcat rotors are vented single-piece G3000 cast iron — adequate for one emergency stop, inadequate for repeated performance use. They have no drilling, no slotting, and no GEOMET corrosion coating. When the friction ring heats unevenly, the entire rotor expands as one unit, causing warp, thickness variation, and the pedal pulsation Hellcat forums are full of.
Ghost Rotors Hellcat kits use a deliberate front/rear split:
- Front: G3500 metallurgy 2-piece floating rotors — aluminum hat and iron friction ring expand independently under heat via floating bobbins, eliminating the primary cause of front rotor warp.
- Rear: G11H18 metallurgy 1-piece drilled and slotted rotors — premium high-carbon iron matched to rear caliper spec, with the same performance surface treatment.
Both front and rear get diamond slots to sweep debris and hot gas from the pad face, cross-drilled holes for cooling airflow, and GEOMET® coating to prevent the surface rust that develops on uncoated OEM rotors between drives.

777-XAM1014 vs 777-XAM1033: Part Numbers, Diameter, and Fitment
Hellcat brake fitment splits at the 2021 model year when Dodge increased front rotor diameter from 390mm to 400mm. Two Ghost Rotors part numbers cover the platform — they are not interchangeable.
- 777-XAM1014 — 2015–2020 (390mm): Fits Dodge Challenger Hellcat, Charger Hellcat, Redeye, Scat Pack, and SRT 392 from 2015 through 2020. Also fits Chrysler 300 SRT8 from 2005 onward on the shared 390mm Brembo brake platform.
- 777-XAM1033 — 2021+ Hellcat (400mm): Fits 2021+ Dodge Challenger and Charger Hellcat, Redeye, Super Stock, and Jailbreak on the updated 400mm brake specification. Does not fit Chrysler 300 — the 300 SRT was discontinued before this brake update.
Both kits include G3500 2-piece front rotors, G11H18 drilled/slotted rear rotors, carbon ceramic pads, and a lifetime warranty. Confirm your year and trim on the Hellcat brake kits hub before ordering.
Complete Hellcat Brakes: Rotors, Pads, and Calipers Together
Upgrading Hellcat brakes means treating the system holistically. Swapping rotors while keeping glazed OEM pads leaves fade problems unresolved. Installing performance pads on warped rotors causes noise and uneven wear. The correct approach is a matched kit: G3500 2-piece front rotors, G11H18 rear rotors, low-dust carbon ceramic pads, and proper bedding — all designed for the Hellcat Brembo caliper specification.
Ghost Rotors Hellcat brake kits are direct bolt-on replacements. No caliper modification, no hub machining, no spacer kits. The factory Brembo calipers — which are capable hardware — remain in place. What changes is the rotor mass, thermal design, and pad compound that those calipers act on.
- 2015–2020 (777-XAM1014, 390mm): Challenger Hellcat, Charger Hellcat, Redeye, Scat Pack, plus Chrysler 300 SRT8 (2005+)
- 2021+ (777-XAM1033, 400mm): Challenger Hellcat, Redeye, Super Stock, Jailbreak, Charger Hellcat — no Chrysler 300

Street vs Track: What Hellcat Brakes Need for Each Use Case
Not every Hellcat owner tracks their car — but even street-driven Hellcats exceed OEM brake capacity during highway pulls, canyon runs, and drag-strip testing. Here is how brake demands differ by use case:
- Daily street + occasional bursts: G3500 2-piece front rotors eliminate warp from repeated on-ramp stops and prevent the pedal pulsation that makes a Hellcat feel unsafe after a fun drive home.
- Drag strip: Repeated staging-lane stops and trap-speed deceleration heat rotors rapidly. The floating front rotor design handles thermal shock between passes better than single-piece G3000 OEM.
- Track days: Sustained lap-after-lap braking requires rotors that evacuate heat continuously (diamond slots + drilling) and pads that resist fade (carbon ceramic). OEM fails on all three counts within 3–4 laps.

Installation, Bedding, and What to Expect After Upgrade
Installing Ghost Rotors on a Hellcat follows standard pad-and-rotor replacement procedure. Remove the wheel, unbolt the caliper, swap the rotor, install new pads, torque to spec, and repeat on all four corners. Most experienced DIYers complete the job in 2–3 hours; any qualified shop can handle it without Hellcat-specific tools.
After installation, follow the bedding procedure before any hard driving. Proper bedding transfers pad material evenly across the slotted rotor face — critical for quiet operation and full friction performance. Skipping bedding is the most common cause of post-upgrade squeal on performance brake systems.
What changes after upgrade: firmer pedal feel under repeated hard stops, dramatically less brake dust on wheels, elimination of warp-induced pulsation, and rotors that survive seasons of aggressive use instead of months. Every kit is backed by a lifetime warranty and ships free within the continental US.
