I dont believe for a second that the $100 OFNA torsens perform anything like the Fioronis or Nuova Faor diffs. Thats like comparing the transmission in a Dodge Colt to a 6 speed Getrag in a VR-4. Im sure you can tune 6-8 diffs to perform like my 1 torsen will, but it requires changing the diffs!

By the way the BBF diffs that are pictured below work is with conical gears, but the insides are all machined tool steel! Best made regular diffs I have seen. What do you think about these? Also these dont use silicone....they use the same special grease as do the Fioronis. They feel about twice as smooth as a stock diff. I looked on BBF site and these are more around $180 each.
