Idiot question on a rear sway bar for 2013 Impreza 2.0i Base
I am hoping some more experienced folks could lend me some advice.
I have a 2013 Impreza 5 spd hatch base model. I really like the car, and use it for daily commuting as well as driving up mountain passes for skiing. I spend a lot of time with 3-4 people in the car, loaded with ski gear, and with a roof box loaded with more gear. The car gets a bit wobbly feeling left-to-right over 65mph, in high winds, and especially in corners all loaded up with people. Through researching past threads on the subject, it became apparent that my car has no rear sway bar to speak of. I have no experience with adding or changing sway bars (or auto suspension parts of any kind) but it would seem to explain the wobble factor. It looks like a lot of folks go for a 19mm sway bar over the stock one. Will this make the car ride very rough over over ruts and bumps? The thicker bar may make sense since a lot of time I have weight on the roof of the car and 3-4 passengers. Installation looks pretty straightforward. My main question is: since my car has no rear sway bar, what parts do I need in addition to the bar itself? Several people have suggested this bar in previous threads, and it says that it comes with bushings. I know that because my car has no sway bar I will need extra parts, but I'm not immediately sure what those are. End links, brackets and what else? Is there a kit that you would recommend? I'm looking for something cost-effective and straightforward, rather than the most tricked out part available. Thanks everybody! |

As far as I know the car has one, I think 16mm. The 19mm is the WRX stock one. I dont know if the 16 bushings will fit the 19 & I think u can just use the endlinks that are there.
One way is to just look under the back of ur car. U will just see a bar going from one side to the other. I haven't done this yet. Its either that or strut bars. |

Since you have a base with no RSB, you'll need the bar, bushings and clamps, and endlinks. Better description here:

1. Base models have no sway bar.
2. You need sway bar, bushings, mounting brackets, end links, and hardware. 3. I have my stock 16mm bar/bushings available if you want it for dirt cheap. 4. Update your profile so I can see if youre close enough for pickup! |

I'm in the same boat as you, but with a 2012. Base models have no rsb, premium and limited get the 16mm sway bar.
Word on the street is that it only takes around half an hour to install on your own. You'll need all of the parts from that link posted by Angelus911. Alternatively, Perrin makes 19 and 22 mm sway bars for us, which come with all the necessary parts, but they're like $400. Not sure if they're actually any better in any meaningful way. The concensus here seems to be that the 19mm works very well and makes the car handle more neutrally at the limit of grip, whereas the 22mm will make the ride a bit more harsh and will make the car more likely to oversteer. |

I have a stock 16mm bar and bushings for sale too, if more than one person is interested in this upgrade. I will ship it in the box that my 19mm bar came in. PM me if interested.
It is my opinion that a RSB won't increase ride harshness, regardless of what size you install. I'm sure the stock 16mm bar would provide a huge handling improvement over having no bar at all. The 19mm bar provides even flatter handling. It's my guess that a 22mm bar would convert the car too much toward oversteer for my tastes (especially when the roads are wet/slippery), but this is just a guess as I've never driven the car with a 22mm bar installed. |

Thanks for all the excellent info everybody! I also appreciate the sale offers on the stock back. Someone local to me is selling there stock 19mm 2010 STI bar so I will go for that and order the rest of the parts from SubaruGenuineParts which is also local to me.
Cheers! |

In addition to the bar and bushings, you will also need end links, brackets (which install over the bushings), and some bolts to hold everything together. |

Yes, but I'm not sure if the WRX's stock RSB is 16mm or 19mm. I know the STI's stock RSB is the 19mm bar.

I was able to pick up a lightly used 19mm rear sway bar from a 2010 STI locally on craigslist and ordered the rest of the parts from subarugenuineparts.com. Hopefully everything bolts right up!
For other people who might want to order those parts from that website, here are the part numbers: 20464FG000 20466FG000 20470FG000 10108200 902370055 902350001 901000221 |

So you just need the bar? Or bushing also?

I've got one more question for the Nasioc hive-mind.
My parts just arrived from genuinesubaruparts. Two of the nuts are a locking style where the outside is crimped on 3 sides. (I'm not sure what this is called.) The other two are standard and have a more silver/chrome finish. The question is: do the locking nuts go onto the bolts that attach the endlinks to the car (bottom) or the end that attaches to the sway bar (top) ? I have the torque specs for these, but I'm not sure if I should use anti-sieze, grease or whatnot on them. Thanks again for all the help, folks. |

Does anyone else on this thread currently have a 16" stock or 19" (edit: lol 16mm or 19mm) sway bar lying around that they want to get rid of? I have a '13 base model and would love to get one on there.
On a slightly related topic, I've searched around and haven't found anything: My shocks/struts are done, and I've ordered Duralast (I know, sorry, but limited budget) quickstruts from autozone, spec'ed to match the base model. Now I know that the sport models have different (better?) suspension, and when I change my car submodel on AZ's website to "Sport Limited," I get different parts showing up for the quickstruts. Does anyone know if I can put those in instead? Does anything else need to change on the car to be able to do that? Does it actually make any difference? (Would I get the 0.2" lift that the sport models supposely have?) Thanks a lot. |
