Hawk Talon 2010 Lexus GX460 Drilled and Slotted Rear Brake Rotor Set

Precision-Slotted Rear Rotors That Outlast Budget Options on the 2010 Lexus GX460

The Hawk HTC5046 is a pair of Talon drilled and slotted rear brake rotors manufactured to OEM dimensional specifications for the 2010 Lexus GX460. Each rotor is cast from Grade 3000 premium cast iron and finished with Hawk's proprietary Black Magni corrosion barrier coating, which is salt-spray tested per ISO-9227 and engineered to exceed the 240-hour threshold that uncoated or standard zinc-coated rotors fail to reach.

The slotted face design uses Hawk's DTC curved slot geometry, derived from their motorsport-proven DTC racing rotor program and precision CNC-machined into each production rotor to reduce pad glazing, clear debris from the pad face, and improve heat dissipation during sustained braking. The HTC5046 pair is built to OEM weight and production tolerances for proper balance and suspension loading, and each rotor is precision-balanced before leaving Hawk's ISO-certified North American facility to eliminate the harmonic resonance issues associated with mass-market replacement rotors. The HTC5046 is covered by Hawk's limited lifetime warranty and is designed as a direct bolt-on replacement for the 2010 GX460 rear axle.

Key Features

• DTC Curved Slot Design: Hawk's motorsport-derived curved slot geometry clears brake dust and gases from the pad face, reduces glazing, and improves wet braking performance compared to standard vented rotors.
• Black Magni Corrosion Barrier Coating: Salt-spray tested to exceed 240 hours per ISO-9227, protecting the hat, vanes, and non-swept rotor surfaces from rust and corrosion in all climates.
• Grade 3000 Cast Iron: Premium cast iron alloy delivers the thermal mass and damping characteristics needed for SUV weight classes and towing applications on the GX460.
• OEM Weight and Dimensional Specs: Built to factory specifications for proper suspension geometry, caliper clearance, and ABS sensor gap on the 2010 GX460.
• Precision Balanced: Each HTC5046 rotor is balanced before shipping to prevent vibration and steering wheel pulsation at highway speed.
• Limited Lifetime Warranty: Covered by Hawk Performance's limited lifetime warranty against workmanship and material defects.
• Sold as a Pair: Both rear rotors included in one purchase for a complete rear axle replacement.

Frequently Asked Questions

1. What is the difference between the Hawk HTC5046 drilled and slotted rotor and a standard replacement rotor for the 2010 GX460?
   The HTC5046 uses Hawk's DTC curved slot design for improved pad degassing and debris clearing compared to a smooth-face OEM replacement rotor. The drilled holes improve visual heat dissipation while the slot geometry actively clears the pad contact surface during braking. The Black Magni coating also significantly outlasts the uncoated hats and vanes found on standard replacement rotors.
2. Will the Hawk HTC5046 fit the 2010 Lexus GX460 without any modifications?
   Yes. The HTC5046 is built to OEM dimensional specifications for the 2010 GX460 rear axle. It bolts on in place of the factory rotor using existing caliper hardware, hub studs, and brake hardware with no cutting or modification required.
3. Do I need to replace brake pads when installing the HTC5046?
   Hawk recommends installing new brake pads with new rotors for best performance and even wear. Used or glazed pads will not bed correctly on a new rotor surface and can reduce braking effectiveness.
4. How do I bed in the Hawk HTC5046 after installation?
   Perform 6 to 10 slowdowns from approximately 30 to 35 mph applying moderate pressure without coming to a complete stop. Follow with 2 to 3 harder stops from 40 to 45 mph to zero. Allow 15 or more minutes for the brake system to cool. Do not drag the brakes during the bedding process or allow the vehicle to sit with the brakes applied while the rotors are still hot.
5. Are drilled and slotted rotors suitable for a daily-driven 2010 GX460?
   Yes. The HTC5046 is designed for street and moderate performance use on the GX460. The DTC curved slot design and Grade 3000 cast iron specification make it appropriate for daily driving, towing, and canyon driving. Aggressive track use with high-heat brake compounds may accelerate rotor wear on drilled and slotted designs.
6. What is the Hawk HTC5046 warranty?
   The HTC5046 is covered by Hawk Performance's limited lifetime warranty against defects in workmanship and materials. The warranty does not cover normal wear, damage from improper installation, or motorsport use.
7. Does the HTC5046 require any special break-in procedure?
   Yes. See the bedding procedure in the FAQ above. Proper bedding transfers a thin, even layer of brake pad material onto the rotor face and ensures optimal pad-to-rotor contact for maximum stopping power and smooth pedal feel.
8. Is the Black Magni coating on the HTC5046 applied to the full rotor?
   The Black Magni corrosion barrier coating is applied to the hat, vanes, and non-swept rotor surfaces. The swept face of the rotor where the pad contacts is left uncoated and will self-clean during normal braking operation.

Install Instructions

Safely raise and support the 2010 Lexus GX460 on jack stands with full access to the rear wheels. Remove the rear wheels and loosen the caliper bracket bolts. Remove the caliper assembly and suspend it with a wire hook so the brake line is not stressed. Slide the old rotor off the hub after removing any retaining screw if present. Clean the hub mounting face thoroughly with a wire brush to remove rust and debris before installing the new HTC5046 rotor. Mount the HTC5046 onto the hub and thread the caliper bracket back into position, torquing to factory specification. Reinstall the brake caliper and pads. Reinstall the wheels and torque the lug nuts to spec. Perform the Hawk brake bedding procedure before returning the vehicle to normal use.
