Installation instruction for article 928 UFO strut ZR18 ZL18 brake caliper Tuning Audi 200 20V V8 Audi 100 UFO strut adapter Porsche Cayenne ZR18 brake caliper
Here you will learn how to install the Porsche Cayenne ZR18 brake calipers in combination with the 350x32mm Mercedes Benz brake discs on the Audi 100, 200 and Audi V8 step by step.
Please note
Please read these instructions carefully before starting work. If the conversion is too difficult for you, please commission a specialist company to carry out the installation. We cannot accept any liability for consequential damage caused by improper installation. Correct installation and adjustment saves time, costs and trouble.
Disassembly:
- Old brake system (brake disc, brake caliper and brake caliper carrier)
- Remove or process the air baffle or brake baffle or anchor plate (we prefer the removal, as the ventilation of the brake is better ensured).
!!Important!!:
What do you need ?
- Depending on your technical knowledge, about 1-2 hours of time
- Torque spanner with suitable attachments
- Liquid threadlocker
All Audi 200 20V Tubro Quattro and Audi V8 D11 have only the UFO strut. The steering knuckle of the UFO strut has 3 mounting points as standard. Only two are required for the large 6-piston ZR18 Porsche Cayenne calipers. Therefore, you have to adapt the steering knuckle by removing the upper mounting.
The small offset must also be ground flat
This is how the suspension strut should look when finished.
Next, the wheel hubs have to be turned down in diameter so that the brake disc fits over them.
PS: The HP2 strut already has only 2 mounting points as standard, so nothing has to be adjusted there and the adapters fit one to one.
When you mount the rim, make sure that the brake caliper does not rub against the rim. If this is the case, you can counteract this with wheel spacers if necessary, so that the rim has enough distance to the brake calliper. Click here to find our wheel spacers (click here).
Now the conversion with the Porsche Cayenne ZR18 brake calipers and the matching 350x32 Mercedes brake disc is almost complete.
Finally the mobility of the new brake system has to be checked. To do this, turn the vehicle in completely to the left and right and check that nothing is rubbing anywhere, or that nothing is touching the bearing joint, wishbone, etc. The whole thing has to be done in the sprung and braked position.
The whole procedure must be carried out with the suspension on and off.
If there is a collision at full steering angle, it may be possible to counteract this quite simply with steering angle limiters (click here for our steering angle limiters).
