Here are some pics of my homemade 3M-taped splashguards. Again, I just took a set of flat black plastic splashguards from the local auto parts store, and, after making a cardboard template from the fender and bumper, cut the splashguards down to fit the ST. I rough cut the pattern with a razor knife and sanded the final shape to make it smooth. Easy and cheap.
It just rained when I took the pics, so the car is dirty.
