Borrani’s test and quality control program is probably the harshest and most demanding in the industry. Both individual components and complete wheels are subdued to grueling test programmes, which for the most part were specially developed for this purpose. Materials research methods are derived from Formula 1 and aviation technology.
When calculated results are compliant with internal and regulation standards, a series of static and dynamic trials is implemented:
Simulating the wheel behaviour when the car is cornering, this test reproduces the stress in function of the wheel size and the vehicle weight.
The wheel must resist, the impact of a heavy load without deformation or loss of air. The test reproduces a typical pothole or pavement shock strain.
The wheel is submitted to a series of severe acceleration and deceleration cycles.
The wheel runs 2000 km under full load at predetermined speed in a machine simulating 98 non-stop laps of the notorious Nürburgring Nordschleife racetrack.
This trial reproduces the wheel performance and behaviour under fatigue for a whole lifecycle of the automobile.
Borrani wheels are approved by the reputed TÜV SÜD homologation institute, and type approved by KBA, the vehicle registration agency of the German Ministry of Transportation.
