While Delphi states that its brake discs have been fully compliant with R90 quality standards for many years, its discs for new vehicles launched after 1 November 2016 will now be R90 homologated and certified. The recently introduced R90 legislation only applies to discs or drums for vehicles launched after 1 November 2016. Delphi is also securing R90 certification for discs fitted to older vehicle applications.
