Adapter for BMW M5 (E39) [REAR]

Brake caliper adapters for the rear, dedicated to BMW M5 (E39) [REAR]. The adapters enable the installation of a 4-piston caliper [Porsche Panamera (rear axle)] BREMBO on a 370x24mm disc [BMW M4].

A 370x24mm disc [BMW M4] combined with a 4-piston caliper [Porsche Panamera (rear axle)] BREMBO allows you to obtain high and repeatable braking power.

The set consists of brake caliper adapters and mounting screws.

For proper installation, the brake caliper must be lowered on the mounting feet by 12 mm.

Product weight: 268

Vehicle axle: rear

370x24mm discs [BMW M4] OE codes:

- 34212284812

The adapters are made of high-quality duralumin / magnesium aluminum, which provides them with low own weight (including low unsprung mass), combined with high mechanical strength comparable to steel.

The adapters are anodized for anti-corrosion protection.

Depending on the rim model used, it may be necessary to use spacer rings - this depends on the rim's ET parameter.

Brake cables:

To take full advantage of the modification consisting in replacing the brake calipers with more effective ones, it is also worth taking care of the brake lines and replacing them with steel-braided lines.

If you change to a larger brake disc diameter, it is worth ordering longer brake lines. Their length should be adequate to the difference in the radius of the brake disc. For example, if the old brake disc has a diameter of 300mm, its radius is 150mm. The new brake disc has a diameter of 330mm, so its radius is 165mm. In this way, we obtain a difference in the radius of the brake disc of 15 mm. New brake lines should be longer by this minimum value.

Brake pads:

When installing brake discs with a thickness of 30 mm, it is recommended to use brake pads with a height of 15-15.4 mm (standard pads are 16 mm high).
