Using your Cusco Rear Cross Member Power Brace is easy. First, make sure your car is parked on a flat and stable surface. Use the included installation hardware to attach the brace to the rear right and left sides of your 2022 - 2025 Subaru WRX. If you're not confident in doing the installation yourself, it's a good idea to have a professional mechanic handle it. When it comes to maintenance, the corrosion - resistant Cusco Blue Power Coating means you don't have to worry too much about rust. But it's still a good practice to regularly check the brace for any signs of damage or loose bolts. If you notice any issues, replace the parts or tighten the bolts as needed. Keep enjoying the improved handling and stability this power brace brings to your car.
