I was just wasting time online last night and came across this type of differential. I talked to a co-worker who has this system installed in his FWD Mazda 6 and says it's the best thing for differentials since sliced bread. The concept is cool, I was just wondering how well it works in our Front, real world style (Using 4WD in normal traffic conditions as well as Off-Road). Has anyone messed with this?
I really do not have any way of justifiying the expense, just curious.
