Fitment: This DBA 4000 rotor is designed for 2008 - 2021 Subaru STI models. Features: It's for the front position. The Tri - Symmetrical curve slots give a quieter, more responsive, and smoother brake feel. The Kangaroo Paw ventilation system with 144 diamond and tear - drop pillars boosts heat dissipation. The XG150 High Carbon Alloyed Iron prevents warping and cracking, and extends the rotor's lifespan. Thermographic Temperature Monitoring uses heat paint markings to show peak braking temperatures. Paint protection on non - friction areas stops corrosion and rust. It comes with a 12 - month or 12,000 - mile warranty from the purchase date and is sold individually. These features make it ideal for street cars and weekend track warriors. DBA slotted rotors are a durable alternative to drilled rotors, with the same hot brake gas dissipation effect.

Using the DBA 4000 rotor is straightforward. Just install it as you would with a standard rotor on your 2008 - 2021 Subaru STI. When driving, you'll notice the improved braking performance right away. For maintenance, regularly check the rotor for any signs of wear, like uneven surfaces or excessive rust. If you see the heat paint markings on the rotor changing, it's a sign that the brakes are getting hot, and you might want to take it easy on the braking. Also, keep the non - friction areas clean to maintain the paint protection. Remember, this rotor has a 12 - month or 12,000 - mile warranty, so if you have any issues, reach out to the seller. Drive safely and enjoy the great braking experience!
