your car or the shop's project car? Are you spinning a tire when exiting turns?
just gotta make sure the ratio equals the center diff ratio.

I thought the center diff was 1:1?

that's on my to do list too, but it's easier when you have a GC you just need to find a VLSD out of a 00-01

The rear diff in the 2007 WRX is a LSD. Is the gears the same? and the axles splines? as the Open diff on the 06-07 impreza? if so it would swap over pretty easy in our cars if you did a whole housing swap. Boy a LSD would really add to the car. Can anyone tell us about the fittment. As far as axle splines if the 07 WRX wagon axles are the same as the 2.5i wagon axles then we know the splines are the same. Thanks Tony now I have another mod to ponder around in my head. Tony get that resinator swap done yet?

the rear diff in all WRX's is LSD. the axles are the same. the splines don't matter as there is an inner CV that covers the mating. The housing for the diff is basically the same. all you need to do is swap the ring and pinion from your set to the set you get from a WRX. (at least that is what I read/hear) Subie sport had a good writeup in Dec. 06 on putting a Quafie unit in a TS.
02+ WRX stock viscous LSD is 3.9 ratio. it's a straight bolt-in for most Scoobs w/3.9 ctr diff...TS wag, GCs w/2.2, OBS, etc. Depending on application, you will probably have to swap out rear axles to fit the new diff.
GC/GD RS and Forester 5MT cars have 4.11 center diffs, and the WRX swap wil NOT work. Forget the DCCD swap, the associated wiring and controls are more hassle than they're worth. If you are doing a full WRX swap with wiring harness, it's doable, but be aware that this is a HUGE project with extended development/mechanical downtime.
BTDT several times.
the rear LSD give the car more of a rear-drive feel, and helps throttle steer in low-grip conditions.

That's funny right there ;D
try Norm's Used Cars in Newcastle (just N of Bath). They have a whole operation devoted to recycling parts off crashed Scoobs.

my rally car wears lots of recycled bits from these guys. they are an especially good source of used stock scooby wheels. they don't always have WRX parts on hand, but have started getting a few in as more and more ppl wad their WRXs into tinfoil
