Using this DBA 4000 Series T3 slotted front rotor is easy. Just make sure your vehicle is a Subaru STI from 2004 - 2017 or a Subaru WRX from 2008 - 2014 with 5x100 STI Brembo Swaps, as it won't fit cars without Brembos. When installing, follow the standard brake rotor installation steps for your vehicle. As you drive, enjoy the quieter, smoother, and more responsive braking performance. For maintenance, regularly check the rotor's surface for any signs of wear, cracking, or warping. Keep an eye on the heat paint markings to know the peak braking temperatures. If you notice excessive heat or other issues, it might be time for a closer inspection. To prevent corrosion, avoid driving through deep water or salty environments when possible. And remember, it has a 12 - month or 12,000 - mile warranty from the purchase date. If you have any problems, reach out to the seller.
