Opel Kadett Calibra Vectra Porsche Brake calipers Adapter Brake system Brake caliper adapter for front axle

  • ✓ 314x28 93178721 Vectra C GTS brake disc
  • ✓ 4-piston 996351425 or 426 brake caliper
  • ✓ front axle

Brake caliper adapter for the large Vectra C GTS brake discs 314 x 28mm to be used in conjunction with the Porsche Boxster S and 996 brake calipers (996.351.425 or 426).

Can be used without modifications on all Opels with a standard 5x110mm bolt circle such as Omega A B

Otherwise with wheel hub conversion to 5x110 bolt circle on all Opel models e.g. Astra, Calibra, Kadett & Vectra can be mounted directly on the strut.

low conversion effort for enormous braking power.

Advantages:

  • Extreme deceleration values also in connection with our rear axle brake system
  • The material certificate included in the scope of delivery enables entry by individual acceptance even for series vehicles
  • directly suitable for the above models and can therefore be restored to the original condition at any time without any problems
  • our EPYTEC brake caliper adapters do not require you to send in your serial parts, no re-welding - re-milling or re-drilling. 

Scope of delivery:

  • material certificate
  • 2x brake caliper adapters for Vectra C discs with Porsche 996 brake calipers
  • high-strength screw material

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.

Ich muß sagen es is gut gefertigt und sieht sehr stabil aus. Verpackung und Versand gibt's auch nix dran zu meckern. 😉 Zur Passgenauigkeit kann ich leider noch keine Angaben machen, da sie noch nicht verbaut sind. LG

  • 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
