I buy a lot of items for my 2005 Evo VIII here at lancer shop. I have 10 positive things to say to 1 negative. That's a ratio that keeps me coming back. I had ordered 2 items and because they didn't have the colors I wanted in stock they gave me an option to change my shipping to next day air I just had to
Choose different colors. No big deal it was a motor mount who is going to see that anyways haha! Lancershop is a one stop and shop.
