Brake caliper adapter for the front axle of the BMW X3 X4 series to drive the BMW G30-31 4-piston brake calipers in conjunction with the BMW F07 F01 374x36mm brake discs.

The BMW G30-31 4-piston brake calipers are simply bolted to the original axle mount in place of the original caliper using our tuning adapter.

Advantages of this braking system:

  • extreme deceleration values also in conjunction with our rear axle brake system
  • The material certificate included in the scope of delivery enables registration via individual approval, even for standard vehicles
  • Fits directly to the above-mentioned models and can therefore be easily retrofitted to the original condition at any time
  • our EPYTEC brake caliper adapters do not require your standard parts to be sent in, no rewelding, re-milling or re-drilling.

Required components:

  • BMW G30-31 4-piston Brembo brake callipers part no.: 34116891303 / 34116891304
  • Brake disc from BMW F07 F01 374x36mm Part number: Left: 34116789543 / Right: 34116789544

Scope of delivery:

  • 2x brake caliper adapter for the BMW X3, X4 series
  • Matching screw set
  • Material certificate

Tips, information and advice:

  • To improve ventilation of the brake system, we recommend removing the anchor plates/brake dust plates.
  • For easy mounting of the rim, we recommend purchasing two of our wheel mounting aids at the same time >>go directly to the article here<<
  • We cannot give you a generalised answer as to which rim size you can ride after your brake conversion. There are simply too many different wheel rims. For this reason, we have developed a template with which you can easily check whether the brake system kit fits under your rim. We have included a link to the template in the description. If your rim does not fit, you can simply use wheel spacers. >> Go directly to customised wheel spacers <<
  • Install the adapter with the required components and then check whether new brake lines are required, as the old ones may not be long enough or the connection may not fit, depending on the model. Due to the significantly better efficiency, we recommend switching to steel braided lines. We have developed a steel braided line configurator especially for this function, which you can use to assemble and then install them according to your requirements. Click here for the steel flex configurator >> Configure steel flex brake line <<
  • The handbrake cable must always be used from the installed calliper, which means that the new handbrake cable may have to be adjusted slightly. For conversions in which the original calliper is still used and the original handbrake cable can be used, you may have to route it more directly to compensate for the larger disc diameter and longer travel

Please note that our articles have been designed for racing and motorsport. Use in public road traffic usually requires an individual approval in accordance with § 21 StVZO by an officially recognised expert. Further information can be found under TÜV Süd. For the individual approval, we will provide you with an expert opinion or material certificate, if available.

  • Can I also use other brake discs as specified in the required components?
  • No, unfortunately that is not possible. The reason is simply: all brake calipers have different heights and depths. If another brake disc is installed, the brake caliper would either not fit on the adapter or not run in the middle of the brake disc. But if you want to install a different brake caliper, we also have an option for you. You can have a custom-made product made for you, take a look at the following link for more information: https://epytec.de/uk/custom-made-products/brake-technology/adapters-for-brake-systems
