How to: Install wrx rear sway bar on a 2.5i 08+
Here a tutorial about how to install a rear sway bar on a 2008+ Subaru Impreza.
I used a sway bar from a 2011 WRX which is 16mm thickness. You can use one from a 2008 to 2011. 2008 -> 15mm 2009-2011 -> 16mm First lets start with the hardware that you need. Go buy them at a dealer: 2x Bracket -> 20466FG000 4x Bracket bolt -> 010108200 2x Bushing -> 20464FG000 2x Endlink -> 20470FG000 2x Endlink Nut -> 902370046 2x Bottom Bolt for Endlink -> 901000221 & Nut -> 902350001 (or you can use a M10x90mm or 3/8- 3"1/2 with the nut) You can use washer on the bolt if you want like i did Once you have all of the hardware needed, 1. Grease the bushing and the bar (they goes outside the metal sleeve) 2. Jack the rear of the car and secure it with Jack stand. 3. Bolt the endlink on the control arm 4. Slide the bar under it. The small curve on the bar goes upward and the bushing goes in the rear of the subframe bracket (You should see it). On a sedan with double exhaust it may be a little harder to slide it in. 5. Install the bracket and tight them in place 6. Bolt the endlink to the sway bar (Do not tight the bolt) 7. Put the car on the ground 8. Tight the endlink nut with wrench and Hex key That how it should look like Left side Right side And go for a ride! For me its day and night, there is no more rebound from the rear suspension and its more stiffer! All the hardware (Except the bar) cost me around 30$.

Looks great! Those parts look familiar =) I'm glad you're enjoying them!
It may be easier for you guys to simply go on ramps. That way the suspension is already loaded so you can untighten/retighten bolts much easier. This is what I upgraded to: |

Thanks for the write up. I don't have ramps, so I will probably let my mechanic just do it anyway. Any idea how much they should charge since it's just about 10-15 minute install?
Or should I save the labor costs, buy the ramps now and be proactive for future DIYs? |

a friend and I did his rear sway bar without any ramps, granted we both are pretty lean guys. if your car isnt lowered, and you're on the smaller end of the body size scale, this can be done with the car on the ground.

Sublinux, how much did you spend on the bar and all the parts from the dealer?

I have an 08 STi bar (18 mm) on my 08 Impreza. Planning on upgrading soon and will be selling the bar then. If anyone is interested I will let you know when it goes up for sale.

That looks like it is for an upgrade to a previous sway bar. If your putting it in the 2.5i without one in it already.. You'll need the bar, bushing.. Like the Amazon has.. Plus endlinks, the end link brackets and bolts

I'm fairly sure that the OEM bushes do not require grease. Mine did not have grease from the factory. It will only serve to trap contaminants.
Also did you notice that the bushes for the 16mm bar have the diameter symbol followed by '15mm', meaning it has a 15mm hole. I checked a factory 16mm bar and bush and they were the same. |

Google would be your best bet.
It should be noted that FRONT sway bars between Naturally Aspirated and Turbo model Imprezas are not interchangeable though. Atleast for the 08+ models. Last edited by lukethedork; 11-13-2014 at 07:44 AM. |

I know I'm digging up an old thread here, but I just bought a used rear sti sway bar. However the tiny little boots on the stock endlinks are both leaking some grease, is this a problem to worry about?

Well i guess thats your call... You could always try them and see how they hold up... A new set of endlinks is not very expensive if you go oem... Might be worth it to just get new ones now rather than the near future when your getting all kinds of clunking sounds from the rear end ha |

Thanks for the reply. I wasn't aware that those little boots could cause any issues. With my old '00 forester the end links had no boots they were just a solid piece with hardly any play; although I'm sure the suspension is a bit more significant in the Impreza. |

Hardware price question
sublinux,
you said all the hardware except the bar cost you $30. I was wondering where you got your hardware from. All of the online dealerships I have been on come out to about $130 for the list of hardware minus the bar. If I could save $100 that would be nice, please let me know! Thank you. |

I know I'm a month or two late here but I just did this install for relatively cheap so I thought I'd share where I picked up my bar and hardware. sublinux did this 4 years ago so I'm guessing that if his hardware only cost $30, he's either exaggerating or was able to find used end links on the cheap (they look used in the pictures). However, all of the part numbers listed in the original post are still valid. Here's my list: WRX oem bar - subaru parts depot - $86 bushing - subaru parts depot - $4.50/each = $9 bushing bracket - subaru parts depot - $3/each = $6 end links - amazon - $17/each = $34 (http://www.amazon.com/20470Fg000-Rear-Stabilizer-Subaru-Febest/dp/B00DMA477C) remaining hardware: bracket bolts (subaru calls them flange bolts) - dealership - $5/each = $20 endlink nuts - dealership - $2/each = $4 bottom bolt (x2) and nut (x2) - home depot - $5 total My cost - $164 (would go down if you were smart and didn't pay the dealer $5 per flange bolt like I did, can get at home depot for much less) Also, I was sketched out by the Febest brand end links from Amazon but they turned out to be pretty stout and I figured for $17 it was a no brainer to at least try them. Cheers |

Hey guys - hate to bring up an old thread (again ... appears this one has been brought back from the dead several times already!) but I have a question.
I'm hooking my 2010 2.5i Premium Sedan up with a 2009 WRX Rear sway bar + hardware install. I happen to work at a dealership so getting parts isn't a big deal. The one question I have is a slight discrepancy in part numbers. The guide here lists the bushings as part number 20464FG000 ... but the parts catalog lists them at 20464SC010. The FG000 didn't supersede to the SC010 ... but the parts catalog is rarely wrong (if here). Anyone have any insight into this? |

does it fit the bar and the d clamps? that's what counts. also, FYI, the 08-14 STi, and 15+ rear sway will also fit your chassis... the 16mm rear is pretty worthless, even on a stock car. i run a 19mm 2011-2014 STi rear swaybar on my wife's fully stock 2012 impreza sport, which came stock with a 16mm rear. and I have a 20mm 2015 STi rear sway on my 08 WRX. |

Hi there everyone, resurrecting this ancient thread since it was really helpful to me! In the second post, I see what looks to be some sort of reinforcement braces added to the mount bracket bottom bolt and the the control arm pivot mounting. What is that and where could I get a pair?
