Honda Civic Si Brake Rotor (1) - Front - DBA - 4000 Series Plain - `06-`15 is a direct-fit front rotor engineered for 2006–2015 Civic Si models. It delivers DBA's 4000 Series construction with a smooth OE-style finish for drivers who want proven metallurgy without a drilled or slotted appearance.

Cast from XG-150 high carbon alloyed iron and processed with Thermal Stability Profiling (TSP), this rotor is built to handle repeated high-stress braking events. DBA's patented Kangaroo Paw ventilation uses 144 diamond and teardrop patterned pillars to raise surface area and improve cooling; compared with traditional straight vane designs, DBA reports up to a 30% increase in surface area and a 20% improvement in cooling efficiency. The 4000 Series HD plain variant keeps an OE look while offering corrosion-resistant packaging, THGP thermo-graphic paint markings and direct-replacement fitment for straightforward installation.
