DURABLE BRAKE DISC -- The brake disc is made of stainless steel reinforced material, with strong heat dissipation and decontamination and drainage design, which has high corrosion resistance and good heat dissipation performance. HIGH QUALITY BRACKET -- High-strength aluminum alloy discs, the edge ribs increase the strength by more than 30%, and have a longer use time. FLOATING BUCKLE DESIGN -- The stainless steel floating buckle design prevents the outer disc from being directly locked with the hub, leaving room for expansion to solve the problem of disc rubbing. ADVANTAGES -- The floating disc has super heat dissipation, high hardness, high corrosion resistance, and has the advantages of stamping and forming. PROCESSING TECHONOLOGY -- The disc adopts full CNC engraving and milling, anodizing, laser marking, and high quality stamping. Each disc comes with 6 adapter screws. Description: Product category: brake disc Item No.: IIIPRO ordinary floating disc Color: black, red gold Size: 160MM, 180MM, 203MM, 140MM Material: aluminum alloy inner frame + stainless steel outer frame Material: stainless steel brake disc + aluminum alloy bracket Packing: genuine boxed single piece Color: black/red Size: 140/160/180/203MM Hole distance: The distance to the center of the hole is 44MM Weight: 140mm 84g /160mm 106g 180mm135g/203mm 172g Process: Full CNC engraving and milling, anodized laser marking, stamping forming The Benefits of Floating Discs: The floating disc appeared to solve the problem-after the continuous friction temperature of the body disc increases, due to thermal expansion and contraction, the temperature of the center position of the disc and the edge position of the disc are different, and the degree of expansion is also different, generating internal tension, causing the disc to deform and brake failure . Generally speaking, there are two kinds of materials inside and outside of the floating disc and connected by rivets. This connection is non-rigid and has a certain amount of freedom. On the one hand, it reduces heat transfer and on the other hand solves the problem of internal stress, so it is relatively stable. Packing list: 1 * floating brake disc(Presented 6 screws )
