Progress: the brake/suspension assemblies are done... and as scary as it was to cut off the kit's rear diffuser fins to install PE parts, it turned out really well. The alignment of the fins isn't perfect, it is close and I don't think anyone will notice, it is the bottom of the car. I wish I had remembered to take a couple pics of the process. I think I painted the satin black too soon and the Zip Kicker hadn't fully evaporated so it made the paint pretty nasty. While sanding off the bad paint, I broke a few fins off and had the opportunity to correct some slight spacing issues. This time I actually washed it with soapy water before painting and now the first layer of paint looks really smooth. Still obviously some sanding marks, but I'm hoping that a few more layers of paint will take care of it.
