How to Upgrade Kia Stinger GT Brakes (2018-2023)

Upgrading the brakes on a 2018–2023 Kia Stinger GT is one of the smartest bang-for-buck modifications for this 365-horsepower, ~4,000-pound grand tourer. The factory Brembo 4-piston front calipers are strong, but the one-piece 350 mm rotors and OE pads fade quickly under repeated hard stops and canyon or track use. This step-by-step guide walks you through the exact parts, torque specs, and install procedure to give your Stinger GT (and the platform-mate Genesis G70 3.3T) the stopping power and fade resistance it deserves.

Why the Kia Stinger GT Needs a Brake Upgrade

The Kia Stinger GT needs a brake upgrade because its curb weight and power outpace the thermal capacity of the factory rotors and pads. The RWD Stinger GT weighs roughly 3,829 lb and the AWD model about 4,023 lb, with 365 hp and 376 lb-ft from the 3.3L twin-turbo V6 (Lambda II) pushing it to 60 mph in about 4.6 seconds. That is a lot of energy to convert to heat every time you slow down.

The GT and GT-S trims come with Brembo 4-piston fixed front calipers clamping 350 mm (13.8 in) one-piece rotors, with 340 mm single-piston sliding calipers at the rear. Those calipers are excellent, but owners consistently report two weak points during spirited driving: OE pads that glaze and fade after a few hard stops, and single-piece rotors that build heat and can develop pedal pulsation (warping) over time. Upgrading the rotors and pads — not the calipers — solves both issues at a fraction of the cost of a full big brake kit.

Kia Stinger GT Factory Brake Specs

The 2018–2023 Kia Stinger GT-S ships with a Brembo front brake system that any upgrade must work around. Knowing the factory dimensions tells you exactly which rotors and pads will bolt on. Here are the numbers that matter before you order parts.

Note that the base 2.0T Stinger uses a smaller 320 mm front rotor with a single-piston sliding caliper, so always confirm your trim (GT, GT1, GT2, or GT-S) before ordering. The Genesis G70 3.3T shares the same Brembo-equipped front architecture, so the parts below cross over to that platform as well.

Best Brake Upgrades for the Kia Stinger GT

The best Kia Stinger GT brake upgrades keep the factory Brembo calipers and replace the rotors and pads with higher-temperature, fade-resistant components. Below are five proven options we stock and install at NLP Performance in Tampa, FL, from a track-focused 2-piece rotor conversion down to direct-fit performance pads.

The EBC Racing 2-Piece Floating Conversion is our top pick because it converts the heavy one-piece factory rotor into a lightweight 2-piece design: an aluminum center hat bolted to an SG-grooved iron friction ring. The result is reduced unsprung and rotational mass for sharper turn-in, plus far better heat dissipation so the pedal stays firm lap after lap. At around $900 for the front pair, it delivers big-brake-kit thermal behavior while retaining the OE Brembo calipers.

If you want everything in one box, the Power Stop Z26 Street Warrior kit pairs drilled-and-slotted front rotors with Z26 Extreme carbon-fiber ceramic pads and all the hardware you need. Around $363 for the complete front kit, it is the value pick for daily-driven Stinger GTs that see the occasional canyon run. The drilled-and-slotted rotor face helps vent gas and water, while the Z26 pad compound bites harder than OE without the brake dust of a track pad.

The EBC USR (Ultimax Sport) slotted rotors are the pick if you want a clean, direct-replacement upgrade that looks and behaves close to stock but resists fade and pad glazing far better. The fine "sport slots" keep the pad face clean and de-gas the friction surface without the crack-prone stress risers of cross-drilling. Pair them with a performance pad below for a balanced street setup, typically in the $380 range and often shipping free.

Running factory or slotted rotors and just want more bite? The Power Stop Z26 Extreme Street pads are a carbon-fiber ceramic compound that ups initial bite and high-temp performance while staying quiet and clean on the street. At roughly $105 for the front set with hardware included, they are the easiest, cheapest way to sharpen the Stinger GT's pedal feel in an afternoon.

The DBA XP (Xtreme Performance) pads are a carbon-metallic compound built for street cars that see hard, spirited driving and the occasional track day. They offer a higher operating temperature ceiling than OE and strong, consistent bite when hot, and at around $93 (down from about $169) they are one of the best pad values for the Stinger GT. DBA's Kangaroo Paw backing plate design also helps with cooling and pad-to-caliper fit.

Kia Stinger GT Brake Upgrades Compared

Here is how the five upgrades stack up side by side. Pick the row that matches how you actually drive: a track-day Stinger wants the 2-piece rotor conversion, a daily driver wants the complete Z26 kit or a rotor-plus-pad combo, and a quick weekend refresh can start with pads alone.

How to Install Kia Stinger Brakes: Step-by-Step

Installing front rotors and pads on a Kia Stinger GT is a straightforward one-to-two-hour job per axle with basic hand tools. The Brembo front caliper is a fixed 4-piston unit, so the caliper unbolts from the knuckle as a whole rather than flipping open on slider pins. Always work on level ground, chock the wheels, and follow your factory service manual for exact torque values.

Tools and supplies you will need

• Floor jack and two jack stands
• 21 mm socket for the lug nuts and a breaker bar
• 17 mm and 19 mm sockets for the caliper carrier/bracket bolts
• Torque wrench (needed for both caliper bolts and lug nuts)
• Brake caliper piston spreader or a large C-clamp
• Brake cleaner, anti-seize, ceramic brake grease, and thread locker
• A bungee or wire to hang the caliper (never let it hang by the hose)

Step-by-step front brake install

1. Loosen and lift. Break the lug nuts loose, raise the front, set it on jack stands, and remove the wheels.
2. Remove the caliper. Unbolt the two caliper carrier bolts from the steering knuckle and lift the Brembo caliper off the rotor. Support it with wire — do not stress the brake line.
3. Swap the pads. Slide the old pads out of the caliper, transfer the anti-rattle clips (or fit the new hardware), and gently compress the pistons with the spreader so the new, thicker pads clear the rotor.
4. Replace the rotor. Remove the retaining screw if fitted and pull the old rotor. Clean the new rotor's friction surface with brake cleaner to remove the shipping oil, then set it on the hub. For the EBC 2-piece conversion, torque the hat-to-ring hardware to spec if not pre-assembled.
5. Reinstall. Fit the new pads, hang the caliper back over the rotor, and torque the carrier bolts to factory spec (commonly around 90–100 lb-ft — verify for your model). Apply thread locker if the OE bolts used it.
6. Wheels and torque. Reinstall the wheels and torque the lug nuts to 88 lb-ft (120 Nm) in a star pattern.
7. Pump the pedal. Before driving, pump the brake pedal several times until it is firm — this reseats the pistons against the new pads.

How to Bed In Your New Kia Stinger Brakes

Bedding in transfers an even layer of pad material onto the rotor and is required for new pads and rotors to reach full performance and stay quiet. Skipping it is the number-one cause of brake judder and squeal after an upgrade. A typical bed-in procedure for the Kia Stinger GT is:

1. Find a safe, empty road and make 8–10 moderate stops from about 60 mph down to 10 mph, accelerating gently between each one.
2. Follow with 2–3 harder stops from about 60 mph to 10 mph without coming to a complete halt.
3. Drive several minutes without dragging the brakes so they cool. Avoid holding the car stationary on the pads (no long stops at lights) until they have fully cooled to prevent pad imprinting.

Our Top Pick: Pros and Cons

The EBC Racing 2-Piece Floating Conversion earns our top spot for Stinger GT-S owners who push their car, but it is not the right call for every budget or use case. Here is the honest breakdown.
