This spoiler is for your 2022 - 2025 Subaru WRX. First, prep the area where you'll install the spoiler. Make sure it's clean, free from dust, debris, wax, and hasn't been freshly ceramic coated. The 3M adhesive requires an installation temperature between 70 - 80 degrees. Before starting the actual install, have someone help you test fit the spoiler and note the proper position. Apply the 3M to the spoiler and remove the ends of the 3M backing tape, leaving enough to pull out later. Put the spoiler in the correct position, double - check the bolt alignment, and start the bolts but don't tighten them yet. Then remove all of the 3M backing tape, press down firmly on the spoiler for 30 seconds along each section. Open the trunk, finish tightening the bolts, and reassemble the trunk cover. It'll have a solid bond after 24 hours and reach full bond after 72 hours. To keep it in good shape, regularly clean it with a mild car cleaner and avoid harsh chemicals.
