I'm not sure how good they are as I've never seen them but the ones I've seen pictures of on suppliers websites don't seem to have the correct line for the stitching. They should fall away slightly toward the back of the car and they appear to be straight on suppliers websites. I'm a teacher of design and technology so when I needed a set, I copied the original patterns , designed them on CAD software and then made them in the correct hardboard on the laser cutter. It took a bit of fiddling and trail runs but they're a perfect fit now. I bought scrim foam, vinyl and thread from Martrim and trimmed and stitched them myself. I've subsequently made replacements for another two p6 cars as once you've got the file right, the laser cutter will keep banging them out perfectly every time.
