- Discs are wear-resistant, for life 30% longer than conventional replacements - Both versions: Standard and Alien are made of extremely shape-retaining, hardened and heat-treated steel - Special surface finish prevents vibrations and improves pad adaptation ( deviation tolerance now of 1/100 mm) - Uniform and decreases in temperature allows a constant pressure point - Floating discs are colored titanium inner rings machined - No annoying rattle in the floaters. The high-quality steel floater in the ride easily used - The galvanized surface protects against excessive Korrossion - The laser technology allows for lightweight construction with fine contours - Each brake disc can be individually guided with brake pads from the TRW-Lucas range
