We will check your request as soon as possible.

They are only intended for use on the racetrack or for display.
If you want to drive this in road traffic, you need an individual operating permit (EBE).
Part certificates cannot be provided.

 

10. What should I pay attention to when installing the racing windshield?

In order to prevent problems, the brake disc should only be changed by trained specialists.
Basically, please note the following:

Brake discs

Only change axles, if necessary note the direction of travel.
Center it correctly and fasten with the prescribed torque in the correct order.
Important: check lateral runout.
When replacing the brake disc, use new Otto Zimmermann brake pads or other approved brake pads (ECE R90 approval).

wheel hub

The contact surface must be bare (there must be no rust or dirt).
Do not apply sliding pastes or similar.
A light spray of a metal-free oil can be applied to facilitate later disassembly.
Contact surface and centering must not be damaged.
The contact surface must be level (hub runout leads to side runout!).

Brake pads

Use Otto Zimmermann brake pads or other approved pads.
Select suitable pads for vehicle type / year of manufacture.
Apply the brakes as professionally as possible, avoid force braking.

Caliper

Check protective caps for damage and replace if necessary.
Check pistons and guide elements for damage and proper function and replace if necessary.
Ensure that the new brake pads move easily in the saddle shaft.

Suspension
Wishbones and stabilizer rubber bushings must not be worn out, replace if necessary.
Check shock absorbers and replace if necessary.
Check the front axle setting according to the manufacturer's specifications and adjust if necessary.

Wheel bearings

Check play and if necessary adjust or secure according to the regulations.
Steering parts Check steering play and adjust if necessary.
Check tie rods and steering damper for damage and proper function and replace if necessary.

Wheels / tires

Check for imbalance and balance if necessary.
Check of vertical or lateral runout, rim runout, rim runout and compliance with the specifications.

 

11. Can the fastening material (screws) be reused when changing the friction ring or aluminum cup?

We recommend that you do not use the fastening material again when changing the friction ring or aluminum cup.
When the friction ring and aluminum pot are screwed together, a tightening torque is applied, which causes the screw and nut to stretch.
If the screw connection is reused and the prescribed tightening torque is applied, it will lose strength.
