I have my WRX 06 parked outside so I can go and look. But what is an ”LSD” apart from the drug (which did not come with the car)? 😉 // Per(Edit: In general I think the 06 and 07 are virtually identical.)
lol 🙂
It’s limited slip differential so if one wheel starts to slip the differential will transfer the torque to the other.
I don’t know how you can tell by looking at the differential though but the guys from scoobynet have told me they the 2006 WRX models also have it.
You are right about 06 & 07, only difference as far as I know is the colour of the front and back lights (chrome instead of silver) and gearknob.
