Testimonial - E85 Z4 3.0i - Quaife LSD - Mr Mladineo


Dear Mr James,

Nearly a year ago I purchased a Quaife ATB limited slip diff from you. After finding a good bmw mechanic the limited slip diff was successfully installed on my Z4 3.0 si. The result was astonishing! Honestly I was not expecting such a good results. Activating SPORT mode and deactivating DTC you have a totally different car.
It passed about 1000 miles after installing the ATB, now I had a thought to change the oil in the differential and I wanted to get an advice from you regarding what kind of oil to use. Guys in the bmw are suggesting me Shell ZSL which is normally used in standard bmw open differentials.
Kind regards!
