| My experience was the same, spent a lot of money to get them set up properly from the most experienced diff guy in the country. Cost quite a bit due to replacing all other bits in the diff. But noisy had whines at certain revs that spoiled the car (daily driver). Agree that the performance is impressive, I reckon the rev range the gears put the car into is superior to stock, not as good as a turbo upgrade, but as good as the CF driveshaft was. Worth doing if you can stand the whining. My mechanic said that leader gears have a bit of reputation as being whiny. Seems that having solid subframe exagarates the whining and the Cusco LSD probably didn't help either. Took them out after a week or two, they are now going into the race car where whining won't be heard over the exhaust. Replacing the NA diff with the leader gears and the Cusco LSD so should be good on the track.
