I bought the car from a guy in California in June when I was looking for impreza’s on I-Club and I had to have it. I have no other info about the rear lip other than its very unique. I do have all the receipts for the car but it way to many to go though in one night the previous owner was very meticulous but I did just pop off and email to him to enquire where he bought it for you guys. AFAIK I have never seen another one posted. Right now the car is all show and no go (at least to much anyways) since this was one of the first victims of the rimmer kits ran to lean and had to replace the engine.
