Dynamic Friction Company Disc Brake Rotor P/N:604-31130
Bring smooth, balanced stopping back to the rear axle with the DYNAMIC FRICTION brake rotor (P/N 600-31130, also written 60031130). It installs as a direct-fit rear replacement across a wide range of BMW models and the Toyota GR Supra — including the 2019-2026 BMW 330I, 2017-2026 BMW 530I, 2016-2026 BMW 740I, 2018-2026 BMW X3 and 2020-2026 Toyota GR Supra. With 48 applications in all, see the Buyer's Guide tab for the full list.
New in the box and ready to install with no modifications required, this rotor is machined to help restore proper braking at the rear of your vehicle.
Designed to match the same form, fit, and function as the OEM rear rotor. Rotors wear as a pair — for even, balanced braking, replace both rear rotors together as a matched set. Sold individually; this listing is for one rotor.
Is this a front or rear brake rotor?
This is a rear brake rotor. It installs on the rear axle of the listed BMW and Toyota GR Supra applications.
What is the DYNAMIC FRICTION 600-31130 disc brake rotor made of?
It's built with premium G3000/G11H18 iron castings, CNC-machined to tight tolerances and then 100% precision mill-balanced for smoother, more stable braking.
Which vehicles does this rotor fit?
It's a direct-fit rear replacement for many BMW models — such as the 330I, 530I, 740I, X3 and X5 — plus the 2020-2026 Toyota GR Supra. See the Buyer's Guide tab for all 48 applications.
Do I need to replace both rear rotors at once?
For even, balanced braking it's best to replace both rear rotors as a matched pair. This rotor is sold individually, so order two for a complete rear-axle job.
Does it require any modifications to install?
No. It arrives new in the box, ready to install with no modifications required, and its non-directional finish helps promote faster pad break-in.
