Using this ABW Motorsport kit is a great way to upgrade your Subaru WRX or STI. First, unpack the kit carefully and check all the parts. Since the parts come with a white gelcoat finish, you'll need to prep them for painting. Sand the surfaces lightly to ensure good paint adhesion. Then, do a dry fit of the fender flares, skirts, and front lip on your car to make sure they align properly. Once you're satisfied with the fit, you can start painting. Use high - quality automotive paint that matches your car's color. When it comes to installation, follow the general body part installation guidelines or seek professional help if you're not confident. As for maintenance, regularly wash your car to keep the kit clean. Avoid harsh chemicals that could damage the paint. If there are any minor scratches, you can touch them up with matching paint. Remember, this product is made to order and will ship 2 weeks after you place your order, and rear spats are not part of the lip kit.
