Using these ABW fender flares on your 2008 - 2010 Subaru WRX is a great way to upgrade its look. First, make sure you've got all the necessary tools for prepping, fitting, and painting. When prepping, clean the area where the flares will be installed to ensure a good fit. For the fitment, note that if you have a sedan, you'll need to do a small trim on the rear bumper section. Painting should be done in a well - ventilated area, following the paint manufacturer's instructions. As for maintenance, regularly clean the flares with a mild soap and water solution to keep the white gelcoat looking fresh. Since they're made to order, expect them to ship 2 weeks after you place your order.
