Question Diff swap

Not sure about this but the front diff of my car (03 WRX) isnt limited slip right? Would it be possible to swap the guts out of an STI front and maybe rear diff (if that would gain anything) and get the adjustable power ratio front to rear?

The center diff is what will allow you to vary the amount of torque transferred to the rear. Having said that, the STi rear diff is physically larger (R180vsR160) and would have to be swapped out complete with carrier, axles and hubs. The front....I'm not sure. I bet there's a ton of people who would love to have that suretrac front diff in their 5spd......myself included!

Lastly, no....your WRX does not have a front LSD. It would be much more fun to drive if it did have one though.
