Ok, I decided to go with the swap of the final drive ratio .


Problem ... Why should I get parts from US, at $1000+shipment+taxes+etc., when every dealer in the world has two differential with the FDR that I want ?

In particullary the 530i (EUR 1100 at the dealer)

Now I'm wondering if the differential of the 530i has the same shape and size of 545i one .

Any pics from below or any idea ?


Thanks, bye!
