Does this kit really fit both the BMW Z4 and Toyota GR Supra?

Yes, the BMW G29 Z4 and the A90/A91 Toyota GR Supra share a platform and use the same brake component specifications. This kit covers the 2019-2023 Z4 and the 2021-2024 GR Supra with identical pads and rotors.

Are both front and rear rotors the same size?

Yes, both the front and rear rotors in this kit are 330mm vented discs with a 5-bolt pattern. The pad shapes differ between front and rear, using FMSI numbers D1892 and D2221 respectively.

Is caliper hardware included or just the lube?

Caliper lube is included with the kit. The pads come shimmed and chamfered. Check your existing caliper hardware for wear and replace as needed separately.

Does this fit the 4-cylinder or 6-cylinder GR Supra?

The fitment data lists the GR Supra from 2021 to 2024 without specifying engine variant. Confirm your specific trim level matches the brake rotor size of 330mm before ordering.

About this part

Product Details

Sharing the same platform underneath, the BMW G20 3 Series, G22 4 Series, G29 Z4, and the Toyota GR Supra all use closely related brake hardware. The EBC S20K2321 kit takes advantage of that, covering both front and rear axles on these vehicles with a matched set of Ultimax pads and G3000 rotors in one package.

EBC builds the Ultimax pads with Aramid fiber and finishes them with the patented Brake-in coating to accelerate the bedding process. Fully shimmed and chamfered at the factory, these pads are ready to run quietly right after install. The G3000 cast iron rotors carry a Geomet anti-rust coating that protects exposed surfaces from corrosion, a real benefit on cars that see rain, snow, or road salt. Both the front and rear rotors are 330mm vented discs with a 5-bolt pattern.

The FMSI pad numbers are D1892 for the front and D2221 for the rear. Vehicle coverage spans the 2019-2023 BMW 330i, 330e, 330i xDrive, 330e xDrive, the 2021-2022 430i and 430i xDrive, the 2019-2023 BMW Z4, and the 2021-2024 Toyota GR Supra. Caliper lube is included, and the entire setup bolts on without modification. EBC backs it with a 10,000-mile warranty.
