I imagine the vLSD would probably be slightly better than a torsen in that sense but only as long as the special goo in it hasn't broken down. Clutch types simply don't care if a wheel is unloaded or in air and will give you consistent and confident power down on corner exit.

From everything I've heard and read, the reason the OSG's are preferred is they are silky smooth unlike many other clutch type LSD's. My Cusco 1.5 way is admittedly harsh and clunky when not driving the car hard. It is still tolerable for when the car occasionally sees street driving.

While I'm no expert on the maintenance of LSD's, I can say I've had mine in the car for 2 full seasons now with no indication of needing a rebuild yet. Also consider that is with the car running on Hoosiers which can be more punishing to equipment than street tires.

Thank you for the in depth reply. That's the level of conversation I was looking for. I did a ton of research into the osg and think this may be the way to go.

How much would you need to change to come down to STU? On paper this car should be really competitive.
