My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!
