How does one brake kit fit both a BMW and a Toyota?

The Toyota GR Supra and BMW Z4 (G29) were co-developed and share the same platform, including identical brake hardware. The G20 3 Series and G22 4 Series also use the same brake dimensions.

Will this fit a 2023 BMW M340i?

No. The M340i uses larger brake hardware than the 330i/430i. Check the fitment list carefully -- this kit is specific to the non-M models listed.

What rotor sizes are in this kit?

The front rotors are 348mm vented and the rear rotors are 330mm vented. Both use a 5-bolt mounting pattern.

Does this kit come with caliper hardware?

It includes caliper lube for the slide pins and pad contact points. The original caliper hardware and brackets are reused.

About this part

Product Details

BMW's G20 3 Series, G22 4 Series, G29 Z4, and the Toyota GR Supra all share the same braking platform. This EBC S20 Kit (S20K2331) takes advantage of that commonality to cover front and rear pads and rotors for all of them in one package.

One Kit, Multiple Platforms

Whether you have a 2019-2023 BMW 330i, 330i xDrive, 330e, 430i, Z4, or a 2021-2023 Toyota GR Supra, this kit fits. These cars share the same rotor dimensions (348mm front, 330mm rear) and pad shapes, making it a direct bolt-on for any of them.

Ultimax Pads for the Street

EBC's Ultimax pads are built with Aramid fiber for consistent daily-driving performance. They come shimmed and chamfered to reduce noise, and the patented Brake-In coating on the friction surface helps the pads seat to the rotors faster during bedding. For a 330i commuter or a weekend Z4 run, these pads are well-suited to the job.

Clean-Looking Rotors

The G3000 OEM replacement rotors have Geomet anti-rust coating on the hat and non-swept surfaces. They are balanced and runout-tested, so you start with a smooth, true surface. The front rotors are 348mm vented and the rear rotors are 330mm vented, both with a 5-bolt pattern.
