BMW E36 E46 Porsche 996 Boxter S Brake Caliper Adapter 345x28 Brake Disc

  • ✓ 345x28 150342270 BMW E46 M3 CSL brake discs
  • ✓ 4-piston 996351425 / 996351426 Porsche Boxter S brake caliper
  • ✓ front axle

Brake caliper adapter on front axle of BMW E36 (all models except M3) for the conversion to the large Porsche Boxter S 4 piston brake calipers, combined with the BMW E46 M3 CSL 345x28 mm brake discs. 

Rims of at least 18 inch is required. With this adapter, you can also have 17 inch rims with BMW E46 discs in 325x28, but for this, the brake caliper of the Porsche must be adapted to the contact surface. 

Required components:

  • brake caliper: Porsche Boxter S, reference left 996.351.425 + right 996.351.426
  • brake disc: BMW E46 M3 CSL 345x28 mm
  • The brake pad must be slightly chamfered at the upper edge, as there is a slight overhang. It doesn't go any lower for reasons of stability

Advantages:

  • high deceleration
  • thanks to the material certificate supplied with the order, it is possible to register your purchase even for series vehicles
  • directly fit to the above-mentioned models and therefore can always be restored to the original state without any problems
  • our EPYTEC brake caliper adapters do not require any sending of your serial parts, no welding, milling or drilling.
  • mounting screws are supplied

Delivery:

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

Die Adapter sind passgenau nur das sie um 1mm Differenz haben, das heisst das die Zange zur Bremsscheibe nicht ganz mittig sind .

Ho scelto questa valutazione perché l'articolo è fatto bene, ma i bulloni sono troppo lunghi.

  • 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
