Starting off the owner, Miles, is an amazing man and really communicative. He is very reliable as I had dropped off my very rare 3.23lsd, and I received it and am extremely amazed at the results of the product. It works amazing in my BMW.

I am extremely happy for the price I paid as it was definitely worth the money, affordable, and for a first timer I'd recommend you come here as you'll leave happy! read more
