Just recieved these today. Was going to go with mpp rear arms but found this company, the reviews for the model s and model x stuff they make are really good so i decided to try them out for my model 3 rwd. Let me tell you the build quality on these are crazy good, packaging is also top notch and came super fast. Gonna be install these in a couple week and ill let you guys know how they are, but so far im impressed
