Part #: 4656S-10. Fitment: This rotor fits 2004 - 2007 Subaru STI and is dual - drilled for 5x100 and 5x114.3. Note: These rotors are for STI models with a 190mm handbrake, allowing you to downsize to WRX 2 - POT rear calipers. It makes it easy to switch to a smaller rotor for 15 - inch wheels in rally racing. This is a single rear rotor. Features: Tri - Symmetrical curve slots offer a quieter, more responsive, and smoother braking experience. The Kangaroo Paw 144 diamond and tear - drop pillar ventilation system boosts heat dissipation by increasing surface area. XG150 High Carbon Alloyed Iron reduces warping and cracking, extending the rotor's lifespan. Thermographic Temperature Monitoring with heat paint markings shows peak braking temperatures. Paint protection on non - friction areas prevents corrosion and rust. It comes with a 12 - month or 12,000 - mile warranty from the purchase date. The DBA 4000 series is an excellent choice for street cars and weekend racers. Slotted rotors are a durable alternative to drilled rotors with similar hot - brake gas dissipation effects.
Using this DBA 4000 series rear brake rotor is straightforward. First, make sure your car is a 2004 - 2007 Subaru STI with a 190mm handbrake if you plan to downsize to WRX 2 - POT calipers. Installation should be done by a professional mechanic or someone with proper knowledge of brake systems. When driving, the rotor's unique features like the curve slots and ventilation system will work to give you a smooth and responsive braking experience. As for maintenance, regularly check the rotor for any signs of excessive wear, warping, or cracking. If you notice the heat paint markings indicating high peak braking temperatures frequently, it might be a sign that you're pushing the brakes too hard. Keep the non - friction areas clean to maintain the paint protection against corrosion. If you have any issues within the 12 - month or 12,000 - mile warranty period, contact the manufacturer for assistance.
