In the area of tuning, the adjustment is the Brake discs This is occasionally an issue that comes up when upgrading to stronger brakes. This is particularly about this Re-drilling the hole circle and/or machining the hub bore of the slices. Such changes are necessary when, for example, larger windows from a different model are combined with special ones caliper adapters to be installed on a car. But how does that work? The process begins with a additional, second bolt circle is drilled into the brake disc. The step is essential to achieve compatibility with the vehicle. In addition, if desired, the Hub bore adjusted to the desired sizeto ensure a perfect fit.
Drill brake discs
However, it is important to note that depending on the design of the discs, sometimes instead of a new bolt circle, so-called slots could be a better solution. The decision is made depending on the disc and the space for the holes. Depending on the company, this can be the case Re-drilling the brake discs can be carried out completely as desired. The processing time can vary depending on the provider and machines 3 and 21 Workshops vary. Is re-drilling actually allowed? NO! You should know that the discs are subsequently modified as a rule only are designed for racing and motorsport. Use on public roads usually requires one Individual acceptance according to § 21 StVZO by an officially recognized expert.
Report or material certificate?
Some providers (if available) do provide one Expert opinion or a material certificate provided to facilitate acceptance, but we are of the opinion that that is hopeless, At least We don't know of any cases, a successful individual acceptance test for road traffic. Adjusting the brake discs by re-drilling the bolt circle and/or machining the hub bore makes it possible to individually upgrade the brake system, but all the fun is hopeless for road traffic. The process nevertheless underlines the Flexibility and the diverse ones Scope in the area of tuning, but also requires expert execution to ensure safety and compliance with the rules in racing.
Re-drilling brake discs – why actually:
- Adaptation for the assembly of larger brake discs other models
- Use of caliper adapters for individual vehicle adaptations
- Possibility to make one additional second bolt circle in the brake disc
- Hub diameter adjustment to the desired size
- Possibility to produce caliper adapters and Brake disc centering rings
- Note on Use on public roads: Usually requires individual acceptance in accordance with Section 21 StVZO
- Sometimes, providing Report or material certificate for individual acceptance.
