I must tell you about the guys at bimmerworld (www.bimmerworld.com)/(www.bimmerworldracing.com). First of all they gave me a great deal on a swap out for my 2001 325i differential for a 3.46 differential. I have only owned my BMW for less than thirty days so I haven't done a lot but these guys were awesome. I pulled in about 7:00 and by 8:00 I was ready to roll. They are a great vendor to deal with and everyone there from James, to Mike, to Josh were awesome. These guys rock! And as far as BMW fanatics are concerned, these guys are definetly at the top of the heap. Top notch service, great pricing on their products and professionalism all around. Go check them out and if you can, catch them on the racing circuit. Good luck to the guys at bimmerworld on your race for the national championship this year. All the best.
