Using your Verus Street Rear Spat Kit is easy. First, gather all the parts from the box - you've got the left and right rear spats and the hardware kit. The simple bolt - on design means you can install it without any major modifications to your 2022 - 2025 Subaru WRX. Just use the rivet - nuts and stainless hardware provided in the kit. As for maintenance, since it's made of hard, durable plastic, a regular car wash should keep it clean. Avoid using harsh chemicals that might damage the plastic. When driving, these spats will help keep road debris away, but if you notice any loose parts during a routine check, just tighten the bolts. That's all there is to it! Enjoy improved aerodynamics and a cleaner car with your new spat kit.
