VW Golf 4 Polo VW Polo 6r WRC 9N Bora Audi A3 TT Audi RS4 B5 brake system caliper adapter 360×32 5mm spacer

Brake caliper adapter, front axle, for Golf MK4 series (wheel bearing housing with with shorter supporting joint holder) to convert to Cayenne ZR18 brake calipers, combined with the original Audi RS4 B5 brake discs.

Suitable for following vehicles with a shorter supporting joint holder:

• Audi A3 (8L)
• Audi TT (8N)
• VW Golf MK 4
• VW Bora
• VW Polo 6r WRC
• VW Beetle
• Seat Leon

Important!:

The adapter is only suitable for cast wishbones OE: 8N0 407 151 A.

These are installed as standard in the Golf 4 R32, Audi S3 8L, and Audi TT 8N 1.8T and the Quattro models. All other models of the Golf 4, Audi A3 series must be converted to this cast wishbone, otherwise no more steering is possible. The stabilizer OE: 1J0411305AF article no. APA100 must also be converted in vehicles that do not have the cast wishbone installed as standard.

We have the right wishbones in the matching accessories and can be ordered directly.

The problem with the wishbone only affects conversions to Z18 and Z17 calipers. With all other adapters that we still have, such as conversion to 4-piston Porsche Boxter, Audi TTRS or 6-piston Porsche Panamera brake calipers for the Golf 4 Audi A3 series, the adapters fit with all wishbones.

As the TTRS disc could touch the wishbone because of its high height, we have developed spacers of 5mm thickness, which are mounted under the brake disc. The discs are thus pushed outwards. In addition, the disc with the plate is perfectly centered on the axle stub. The spacers are naturally contained in the delivery.

Important: These can only be used if the wheel bearing housing is installed with a shorter ball joint mount. This must be checked on the vehicle before installation, otherwise the brake disc will come into contact with the ball joint.
Here you can see the difference between the normal and short ball joint.

In addition, the supplied 3mm bushings must be mounted under the brake caliper adapter, since the thinner spacer disc means that the brake caliper has to move 3mm further to the engine side.

Advantages of this brake system:
