Default Sway Bar

Anyone know if a 08 STI Hatch rear swaybar will fit a 2011 WRX Sedan?
im assuming it will but since the catbacks are different the swaybars maybe aswell?

The stock 08 STi swaybar is nothing to write home about. I'd just get a real aftermarket SB and put it on your car. Seriously I threw mine on the trashheap when I got some whiteline swaybars. Part vs stock was huge. Also if you do the swaybar you should get new endlinks. And you shouldn't run an aggressive sway bar on the back and nothing complimentary on the front. From what I understand it can severly impact driveability.

From my understanding my current rear sway is 16mm and the O8 sti is 18 mm im not looking to spend 200$+ on sways im just looking for something slight to improve handling. im keeping my stock front sway with the sti rear and sti endlinks which is more than sufficient what im looking for

the upgrade to the sti rear is a common mod and many people seem to be very happy with it but I would suggest getting one from a sedan although im not a hundred percent sure on the fitting. Last I saw they go for about $90

I highly doubt a 2mm increase will make a noticeable performance increase. IMO do it right the first time. Save up for some Eibach sways. They're relatively inexpensive.

my 05 wrx wagon 17mm to a sedan 20mm was a good difference. I just want more now so if you can get it free, WHY NOT?

60% increase in bar stiffness. Not sure how that translates to seat of the pants feel, but seems worthwhile.

Moving from 13mm stock ones on GCs to even the 17mm of a WRX, or even 20mm was a large increase.

A buddy of mine even has a 20mm WRX one on his 2.5i and it really made a big difference.

Keep in mind however, these were going from a 13mm noodle to 20mm. Going from a 16mm to 18mm is a smaller difference, although it will still be noticeable. You can surely notice the difference going from 17mm to 20mm.. I'd assume 16->18 would be similar.

If you have a 2011, really look into getting a aftermarket one. The STI one will help and give an improvement, but for the price of sways, I'd go for aftermarket here. You can get adjustable ones. Something in the 20mm range even on a stock suspension will make a world of difference. Don't go much beyond this point as you will get that lift off oversteer or snap oversteer everyone talks about.. however, it's only apparent on snow or when at the limit.

You can get a 19mm STi rear swaybar from SubaruGenuineParts (LINK).

I ordered exactly that and paired it up with Kartboy endlinks front and rear. It's a massive difference going from the 16 mm to the 19 mm in my '11 WRX.

But isn't the rear suspension completely different on the later models? I thought I'd read that they rotate better and don't need such big rear sway bars.

They are different but 16mm is still relatively small and going 18-20 is perfect IMO. i feel like you dont have to go so big on these 3rd gen because they handle very well as they are

Edit: LUMBERZACK and wayward167 have 19mm rear sways currently for sale

My bad. LUMBERZACK must've sold the rear bar. I know he had one cuz I was interested in buying it. wayward167 has a 19mm "spec c" bar with poly bushings. I know that cuz I was interested in that as well. He also has a WL sway bar brace.

Edit: If I knew how to link the thread I would sorry.
