Pretty big difference compared to OE. Excellent stopping power, but the first 500 miles will crush like a car on video. The squeak only occurs at very low speeds, e.g. B. when coming down a driveway or at the end of a slow stop, but that's about it. Find in this video the same noise reduction noise at the beginning of the video. E92 m3 versus Volvo 850 Nurburgring.
