Fits 2018 Crosstrek!
I asked customer service if any product fit a 2018 Crosstrek; they recommended this, so I purchased it to find out. I used both spacers, and mounted in the centermost slot on the plate. There's minimal clearance to the bumper (~6mm), but it does fit. If you wanted to replace the M8x25 screw with an M8x30 and add another 5mm spacer, it might be better idea. But as-is, this does work on an '18 Crosstrek. I went with the GrimmSpeed because it's made in the USA, and the standoff stud is steel, not aluminum. I'm an engineer by trade, and this is a fine product. Customer service with GrimmSpeed was prompt and they knew what they were talking about.
