LSD SuperQ (WPC treatment) Option



Every limited-slip differential is offered in a SuperQ variant. SuperQ units feature reduced chattering and smoother engagement for an enhanced driving experience. With the help of WPC metal treatment, SuperQ limited-slip differentials also come with better heat dissipation and longer wear life with no break-in process required. Just like all limited-slip differentials, SuperQ units allow for locking rate adjustments.

The difference between 1.5 way and 2 way limited slip differentials.

Main difference is the amount of lock up and it's aggressiveness.
Both models will perform same during acceleration but 1.5 way provide less lock up during
deceleration or braking (about 50% aggressiveness).
So for drifting and hard core road-racing, the 2 way works great.  In tight tracks with
tight turns like autocross, the 1.5 works better because there is less push from the back
as you go into the turns.  With a 2 way, it may push the car too much as you go into the
turn and put you into drifting mode on tight turns.
