Default 2010 2.5i Rear Sway Bar?

I've been reading the Subaru homepage and I notice the suspension section states there is a rear stabilizer bar. I was wondering if 2010 2.5i owners can confirm a rear sway bar.

I'm going to go with no rear bar.

Cars101.com is pretty reliable for Subarus and they don't list it as a change for 2010, nor do they list it in the suspension description for the 2.5i, 2.5i Premium, or Outback Sport. It does explicitly state that the front setup has a stabilizer bar, but none for the rear.

http://www.cars101.com/subaru/imprez...2010.html#2.5i

Suspension: 4 wheel independent.
Front: strut with lower L arm, and stabilizer bar
Rear: Double Wishbone suspension

This link from Subaru.com:

http://www.subaru.com/vehicles/impre...res-specs.html

Dosen't mention sway bars, front or rear, at all.

It's on the chasis setup page:

http://www.subaru.com/vehicles/impre...res-specs.html

You notice how they use stabilizer bar twice. However, if you look at the spec section, it doesn't list a rear sway bar though.

I had a chance to look under the new 2010 Imprezas at the dealership, there are no rear swaybars.

Install a rear bar: http://turninconcepts.com/index.php?...1078_1106_1108

Since you do not have one from the factory to begin with, you will have to purchase a pair of bar bushing brackets, as well as for bolts and nuts, from the dealer.

We installed one onto my friend's 2008 2.5i.

Actually, I have the oem WRX swaybar and the 09 struts/springs/hats for a year now. I was browsing Subaru's internet homepage a few weeks ago and saw a swaybar listed for the rear of the 2010's. I was just curious if there was a sudden change.

Yea, I really wish the NA 2.5's had a bit tighter of handling. It's one of the few things that I don't like about my 2007. I even put on better tires than those crappy RE92A tires, which are all around terrible except for about the first 15k on highways....

I upgraded to General Exclaim UHP and they are good in rain/dry and last about 30k. They are not AA traction though, but they last.

Anyhow...How much would it cost to upgrade to WRX suspension? Or would stronger sway bars be enough? I know it does not have a rear sway bar, which I feel is lame...

Might be trading up to get the 2010 2.5 Legacy or Hatchback Impreza...Lease is up in August. I want to see if they will take the tires off the new car off and put the Generals on the newer car. I like the new paddle shifter on the wheel. I really want the 2011 sedan but I don't think it will be out yet. Southern Florida here near the Palm Beach Subaru and Stuart Subaru.

PM me if you are near here and we can talk.

There are a bunch of people over at www.3gWRX.com that have upgraded 08 WRX suspension to 09 WRX suspension, I believe they bought the parts through fredbeansparts.com. You will need the same parts (struts, springs, and tophats) for the 2.5i. I might go with the struts and tophats and then buy upgraded afternmarket springs.

If you want info on the new Legacy, check out www.legacygt.com and www.5glegacy.com, if you haven't already.

Yeah, the 08+ rear suspension is a complete change form the the previous cars. I think that Subaru thought it was good enough for the non-turbo Imprezas with no rear sway. Plus it made the performance gap between the WRX and the 2.5i bigger in '08 when the suspension were a lot closer in performance, before they kicked the WRX up a notch or two in '09.

I just had Rallitek F&R sways installed after having and OEN WRX rear bar on for a year or so, and they make a big difference. The car is MUCH flatter and turns in more predictably, not to mention that I don't get tossed around in my seat as much by the body roll anymore.

I'd think stiffer springs would be a better bet than just sway bars for the base model. They wouldn't hurt, but I just think the base models ride way to soft.

They do ride a bit soft, but I've heard far more stories about people blowing stock struts on aftermarket springs, than not. My choice was to go with F&R sways (Rallitek) first, then after to struts start to get worn out, I'll replace the springs with aftermarket and upgrade to 09+ (not 08, also too soft) WRX Struts at the same time.

Just the upgraded sways make a huge difference!

Thanks for the advice.....so the ralliart sways would make a big difference huh?

I wonder how the new Genesis 2.0T feels in handling? I sat in one yesterday and it feels very nice, didn't drive it though.

I don't have a rear sway bar, I was at a meet last week and they checked out my car since it was the newest one there.

Depends on the size you get for the rear. Typically, most AWD setups seem to be larger bar int he front, smaller bar int he rear. You can rear up on swaybars over in the suspension forum as to why. So if you go with a big, aftermarket rear bar and no change to the front, then you could end up with a combination that is not optimal.

If you go with just a rear bar, I would go with an 09+ OEM WRX rear sway. This will keep the rear slightly smaller than the front. You should be able to find one used for $100 or less. I had this set up on my car with Rallitek endlinks and it was an enormous imprevment over stock handling.

I've since upgraded to the Rallitek front and rear sway combo (19R/22F), and it's even better.

The question is, how much do you want to spend?

Sorry for thread necro, but I was wondering something. I just bought the wife a 2011 2.5i. I'm kicking myself for not keeping my STI front and rear sways when I upgraded. Anyway, I take it from what is in this thread that rear swaybars will fit any Impreza regardless of trim. Can anyone affirm that this is true for the front as well?

Front will NOT fit, exhaust routings are different for the turbo engines.

Thanks for the help. So is Rallitek the only place that does the N/A front still?

I believe so. The 22mm front and the 19 mm rear is a good package for a street set up.

Before I pay for it, can someone confirm that rear sways fit the same regardless of trim? Rear STI and rear WRX bars work on 2.5i's?
