I don,t have their phone number or address, the best way is to do a search for BMW REAR DIFFERENTIALS on your internet explorer. You will find several companies that will sell the Quaife assembly cheaper the factory they say. They also will setup the assembly for you with a choice of gear ratio. My setup is not a Quaife, but a reworked posi unit that holds three clutches, giving about 50% lokup breakaway, almost to tight for the street. It was ordered with 3.73 gears,almost went with 3.64 ratio, the whole assembly was rebuilt to performance specs with whatever new parts they used in doing so. I ordered thru Bimmerworld, cost complete was $1800, it leaves two even blackmarks anywhere or anytime. Oh boy, what a difference the gear change made, you talking about scary. Most of the performance BMW people are on the East coast for some reason, they were all very nice to talk to and deal with. I believe if you go to QUAIFE AMERICA on the net, you will find all the information there is on their products(just accidently found it browsing now).
