I installed a pair of the 3/8" HDPE spacers on my 2016 WRX Limited, and they provided the 3/8" lift intended. The parts were well made and installed fairly easily. The only concern was that the stock rear strut top hat bolts have a large lead-in chamfer and therefore the threads don't go all the way to the end of the stud. With the 3/8" spacers installed, the stock strut bolts only engage about half the nut threads. Will have to see long-term if this presents a problem.
