For the rear you would be able to put one in there if they had one out yet for the 09.

The best option is to do the 6 speed sti drive train swap. If you are planning on making power down the road, a stronger tranny is going to be a must regardless. The sti 6speed tranny is known to be bombproof. For that swap you would need the tranny, sti clutch (might as well put a streetlite flywheel while you're at it), rear diff, driveshaft and axles. Prolly would run you 5K at least. And that is if you plan to install yourself.

If you actually went this route and did this clean, imho it would be the most important and significant upgrade that could have been done.

Are you having a problem with traction? Some people think that only one wheel spins with an open diff, thats not the case at all. You are LIMITED to the max amount of torque the wheel with the least traction has. Therefore if you one wheel on ice and one on dry pavement the wheel on the ice will spin, the wheel on the pavement doesnt have the torque to move.

Enter traction control which monitors this slip, simulates traction with the brakes and the other wheel spins.

High performance front/rear wheel drive an LSD is must IMO esp for launching. However you have AWD so with decent tires launching shouldnt be an issue.

While there are performance gains to be had with LSD there are much better places too start if you want better handling, braking, launching, etc. Tires being the most important, all sorts of suspension upgrades, and even things like weight reductions...

Yes. The drivetrain isn't any different than 02-07 WRXs, so there are several LSD options for front, rear and center.

I'd recommend looking into a front LSD that suits your needs.

What are you doing with the car that you feel you need a LSD?

+1 bad advise with the STi tranny which also didn't really answer the OP question. Stock WRX tranny has improved significantly over the yrs so it will handle decent upgrade in power. I am not sure about adding lsd to a wrx but if you do, pics please. : )

I've been digging on this as well. From what I've seen nobody has done a 180 swap yet. I don't really want a clutch type but it looks like cusco is the only option I've found so far for our 160.

This is the stupidest advice I've read today. The STi drivetrain is not the logical solution to the OP's question.

Also, the 6MT is strong, there is no doubt, but I'm seeing more and more instances of failures. PM Andrewtech and ask them how many they are repairing/rebuilding. Far from "bomb proof". Idiots can destroy anything.

Also, way to over simplify the swap. The 09 is different than the 02-07 WRX's and the swap hasn't been pioneered as clearly as the previous generation.




To the OP---

There are many people who put LSD's (avoid the stock 02-07 WRX vsld unit as its very small and pretty useless) into the R160 and have very good results! I would imagine any R160 LSD would work on the 09 WRX, but don't quote me on that yet.

I was looking into it when I had my 08 WRX, and the final drive for the 06/07 4EAT rear LSDs were the same and few people had made the swap...

So if you can track one of those down it should be a simple job...

Boxer4Racing carries Quaife diffs for front and rear. AFAIK, there's no reason they shouldn't work in the GE/GH Imprezas.


I can't imagine what you're hoping a rear diff will do. Are you spinning your inside rear wheel frequently? Usually the only Subarus with this problem are high power autocross cars (and they usually want a clutch-type since their suspension setups usually result in lifting an inside rear tire) or rally cars (which also want a clutch-type since they're better suited for loose surfaces).

i have thought about doing this in my 08. but if you do put a lsd in, you have to remember to turn off the vdcs everytime you get in your car. if not the first time you start to turn the vdcs will cut power and flash the "traction control" light. i was talking to the dude the tuned my car if he knew how to go in useing open source and turn the vdcs off perminetly, but he said he hasent tried it yet.

I contacted Quaife directly and they said they don't have a rear diff for the 08+. I wouldn't think the 160's in the new cars would be any different but quaife said they didn't have one to fit. I was thinking about a stronger carrier for hard launches.

you can turn the VDC off permanently by pulling the fuse for it (see your manual). unfortunately, you also nix a host of other features (don't quote me on this) such as ABS, cruise control, etc. the VDC system seems to be a very integral, grounds-up component of these cars, so it's tough to get around it, should you ever want to.

That sounds like hyperbole to me. LSDs shouldn't cause any problems with VDC when you're just driving around normally. Even if you get a bit spirited, it shouldn't cause any problems. If you're planning to really push the car, you're probably turning VDC off anyway.

My guess is the OP only wants one so he can say he has one. People who say "wit" and then finish their sentence with ":/" aren't usually looking for something for the purpose of it, usually the bling factor.
