412*74*38mm Carbon Ceramic Brake Rotor

When upgrading to large-diameter braking systems, many performance car owners fall into the misconception that wider friction surfaces always equal better performance. In reality, mismatched friction width and caliper pad size will not only fail to unlock the full potential of a big rotor, but also cause uneven wear, wasted contact area, and unnecessary unsprung weight gain. Our 412*74*38mm carbon ceramic brake rotor is engineered to solve this exact mismatch: it pairs a 412mm oversized diameter with a 74mm standard-width friction surface and 38mm thickened disc body, delivering precision-matched performance for mainstream multi-piston calipers, and striking an optimal balance between braking torque, thermal stability and lightweight design. Unlike ultra-wide rotors built exclusively for extreme heavy-load track use, this specification prioritizes universal compatibility and balanced performance. It caters to users who want the braking advantage of a large-diameter rotor without the hassle of custom brake pads or excessive weight, making it a highly practical upgrade solution for both street driving and regular track days.

• Every dimensional parameter of this rotor is calibrated for real-world usage scenarios, avoiding the over-engineering that drives up cost and weight while ensuring no compromise on core braking performance.
• The 412mm enlarged diameter extends the braking leverage radius significantly. Compared with factory 380mm or 390mm rotors, it delivers a noticeable boost in instantaneous braking torque, sharpening initial brake pedal response and shortening high-speed braking distances. For medium to high horsepower vehicles and heavy performance coupes, this diameter upgrade brings a more intuitive improvement in braking confidence than simply upgrading caliper piston count.
• The 74mm standard friction width is the core design highlight of this product. This dimension aligns perfectly with the pad size of most mainstream 6-piston and 8-piston high-performance calipers on the market, ensuring 100% effective contact between the pad and the rotor surface. It eliminates the common problem of narrow pads running on wide rotors, which causes localized overheating and uneven edge wear. Meanwhile, the standard width creates a shorter heat conduction path, working with the internal ventilation structure to discharge heat more efficiently during continuous braking, avoiding heat buildup in the center of an overly wide friction surface. This specification also supports the use of off-the-shelf standard brake pads, greatly reducing later maintenance costs and replacement difficulty.
• Paired with the 38mm thickened disc body, the structure gains exceptional rigidity and thermal capacity. The increased thickness effectively suppresses thermal deformation and brake judder under sustained high-temperature conditions, making up for the thermal load limit of a standard-width friction surface. This combination allows the rotor to maintain consistent braking output through repeated hard braking on track days, without the weight penalty of an ultra-wide disc.

• This 412*74*38mm brake rotor adopts high-density carbon fiber reinforced silicon carbide (C/SiC) composite material, with a targeted optimization of the carbon fiber weave structure for the standard-width disc design.
• We use a three-dimensional long-fiber weaving process, adjusting the fiber density distribution along the 74mm friction surface to strengthen the stress resistance at the inner and outer edges of the disc. For large-diameter rotors, edge stress concentration is a common failure point under intense braking; this optimized weave effectively reduces the risk of edge cracking and extends service life under aggressive driving.
• The material also delivers long-lasting durability: it resists corrosion in humid or coastal climates, produces minimal brake dust during daily use, and has a service life 3-4 times that of high-performance cast iron rotors of the same specification. For users who alternate between street driving and occasional track days, it offers outstanding long-term value.

■ This specification is positioned as a versatile high-performance upgrade, suitable for a wide range of performance vehicle usage needs, with broader compatibility than extreme-spec wide rotors.

■ It is an excellent choice for factory high-performance vehicles looking to upgrade their braking system without replacing calipers, for street-to-track build owners who pursue balanced daily drivability and track performance, and for performance car modification shops matching mainstream multi-piston caliper kits. It also works well for medium to large performance coupes and performance SUVs that require strong braking torque but want to avoid excessive unsprung weight.

■ For installation, the rotor fits most 20-inch and larger wheel sizes. We support full customization of mounting parameters including bolt pattern, center bore diameter, and hub offset, ensuring seamless compatibility with most mainstream high-performance brake caliper brands on the market. We can also adjust drilling and slotting patterns according to customer preferences for heat dissipation and appearance.

To maximize the performance and service life of this 412*74*38mm carbon ceramic rotor, we recommend following standard professional installation and maintenance practices.

Prior to installation, verify that the brake pad fully covers the 74mm friction surface, with no overhang or incomplete contact. Professional installation by experienced technicians is strongly advised, and we recommend pairing the rotor with dedicated carbon ceramic brake pads to avoid scratching the friction surface. After installation, complete a proper bed-in procedure: avoid hard emergency braking during the first 500 kilometers of use, to form a uniform and stable friction transfer layer between the pad and rotor.

For routine maintenance, clean the rotor surface with pH-neutral cleaning agents, and avoid strong acidic or alkaline cleaners that may damage the ceramic matrix. For users who drive on track regularly, periodically inspect the friction surface for wear and thickness changes. Do not spray cold water directly onto a hot rotor immediately after intense driving, as thermal shock can cause structural damage.
