GiroDisc D1-244 Slotted Front Rotor Rings for 2015-2020 Dodge Hellcat (390-mm)

Vehicle Fitment

• 2015-2020 Dodge Challenger SRT Hellcat - front axle, 390 mm 2-piece rotor setup (uses factory hats)
• 2015-2020 Dodge Charger SRT Hellcat - front axle, 390 mm 2-piece rotor setup (uses factory hats)

Features

• High-carbon cast-iron slotted & vented rotor rings - provides strong braking force and good heat capacity
• Curved-vane internal ventilation - ensures continuous airflow through rotor, improving cooling and reducing fade under heavy braking
• Sold as replacement rings only - reuses existing rotor hats (no new hats included)
• Includes full floating-mount hardware (pins, caps, washers) to re-assemble rotor with OEM hats - ensures correct rotor float and thermal expansion handling
• Direct replacement for factory 390 mm two-piece rotor setup - no machining or modifications required
• Slotted design helps evacuate pad-gases, dust and debris - maintains pad bite and consistent braking even under stress
• Re-use of existing hats keeps unsprung and rotational mass similar to stock, preserving suspension feel and brake bias
• Made in USA from GiroDisc-specified cast-iron for durability and consistent manufacturing standards

Product Description

The GiroDisc D1-244 Slotted Front Rotor Rings provide a cost-effective and performance-oriented way to restore or refresh your braking system on 2015-2020 Dodge Hellcat (Challenger SRT & Charger SRT) equipped with the OEM 390 mm two-piece rotor setup. Instead of replacing the entire rotor assembly, these rings allow you to reuse your original rotor hats while renewing the braking surface - restoring braking performance, heat-capacity, and pad bite.

With slotted and vented cast-iron rings and curved-vane internal ventilation, D1-244 helps manage heat, dissipate pad-gases and debris, and reduce brake fade under heavy or repeated braking. Because the rings come with new floating-mount hardware, re-assembly preserves correct rotor float, thermal expansion behavior, and rotor alignment - ensuring consistent brake feel and pedal modulation. For Hellcat owners looking to maintain or refresh their two-piece rotor setup without the cost of full rotor replacement, D1-244 offers a practical, high-quality solution.
