    Extra S should be used for the WRX or STI for the rear differential and transmission.

    remember however, the STI has a LSD and requires something different for the rear diff. Or you could just have Nuke mix up a batch of his LSD brew, that's what I'm running in my rear diff.

    Dont mean to thread jack, but any opinions on Lucas synthetic 75-90w in the rear end and transmission on a 06 wrx? It's what I put in when I got the car.
