Looking for insight on crankshaft bearings

[Pio72porsche]

I was wondering if anyone could offer some insight on the two brands of crankshaft main bearings seeing that there is big difference in price. I am putting a 930 3.0 together and the case have been line bored leaving me with the option $600 “German “ bearings or genuine Porsche bearings for $1200.

I would/have used the German bearings that have been dry film coated.

Call Henry @ Supertec. They do dry film coating in-house. If you're cross-drilling your crank, they can also drill and groove the #4 bearing as well as cross-drill the crank.
