Default 17mm rear sway bar

Price paid: around $90 shipped
Installation: half an hour to one hour
Improvement: yes
Negative comments: none
Overall opinion: positive

The sway bar that I installed is the one that comes on the WRX wagon(17mm vs 13mm stock RS). I purchased it from subaruparts.com. The only challenge during installation was getting the socket wrench around the black box thing on the passenger side. I later found out that it can be hung out of the way with no damage if the mounting nuts were simply removed.
This product has drastically improved the handling of my car. During manuvers with both hard cornering and braking simultaneously, the back end does not tilt and lift up any more. Overall, the car stays more flat. Steering response has improved, especially on quick sharp turns, even when moving slowly. The car responds to steering imput better than before. In long mellow curves, I am able to womp on the throttle earlier with out the front end pushing as much. Oversteer is easier to induce. My donuts are now tighter...my 180's from a dead stop are tighter (both on loose surfaces). No increase in noise or harshness.
Caution: although its not the 20mm sedan bar, the back end can still get away from you if the conditions are right(In my case -high speed, down hill, mellow righthander in the rain). Some of the car's forgiveness is lost. After some practice, anyone should be able to feel and utilize the full benefits. This car should have came with one already. Is it worth it?..absolutely.
In my opinion; although I have not tried it, I think that the 20mm bar on an RS with stock allignment is excessive for the street. Judging from the cars' behavior with the 17mm, I think that the larger bar would make the threshold between neutral and oversteer too abrupt. I am not an expert driver or always 100% attentive like most of us, so I think that in an emergency situation too much anti sway would be too much to handle. The 17mm bar improves handling yet maintains the vehicle's predictability.

I agree with Peter. My TS had a stock 13mm sway bar. For $50, I purchased an i-club member's wrx rear 17mm sway bar. The car's handling is improved an is predictable. I didn't want to go to 20mm in fear of oversteer. For me, the perfect set-up.

Did either of you guys have any creaking/clunking sounds after you installed the bar? I also put on a 17mm bar - about two weeks after mine went on, the creaking and clunking started...is this normal?

Thanks,

Default creaking

Nope. No creaking before or after attributed to the swaybar. I have always had clunking but I think that it's the spare tire or the wood-like cover thing for it.
I do have creaking however, when its really cold. Mine comes from the front on big bumps or small sharp ones. I guess that's normal.
But, even if the creaking you have is not from the cold, if you lube the bushings with something that is safe for rubber I'll bet that it will go away.

I have a 17mm WRX sway badr that's awaiting my TSs return from the shop. I also got the endlinks from the person who so graciously took a gameboy in exchange for his swaybar . these endlinks look identical to mine, and I was wondering if they're stronger or different in any way? if not I'll keep them hanging around for if (when) I snap my endlinks.

This last weekend I replaced my stock 13mm rear sway bar on my 2005 RS with a 17mm rear sway bar from a stock 2005 RS from another member here on the forum.

I must say, I agree exactly with the previous posts in this thread.

The bar is a GREAT improvement over stock. The car is tighter, there is less lean in the corners, and overall steering just feels more precise. I tested it out on some onramps and I just stay more flat and stable, and can go faster. I felt more like I would exceed my tires' grip rather than feeling like the car would roll over it was leaning so much

I too was a little hesitent to jump from 13mm to 20mm, and I figured that since the 17mm is stock on the 05 WRX sedan, it would be a good place to start for my RS. I am not an "experienced/track/autocross" kind of driver, so unwanted oversteer was something I considered before choosing the 17mm.

I seem to remember reading also that the reason 04+ WRX's have 17mm in the back (even sedan) instead of 20mm is b/c of the revised struts/springs. I figured if I have that same suspension setup, 20mm might be too much.

I'm glad I went with it - it seems controllable, but gives a nice edge that wasn't there before. I guess too sum it up, I'd say "the car should have come with this to begin with."

Install took about 10 minutes. Didn't even put the car on ramps. Just got under, unbolted the bar and bushings, and put the new one one. Didn't even have to move the charcoal canister.

Thanks to AndyU for the rear sway and to Acquacow for help on the install!!

For $35 and 10 minutes, I'd say this is one of the best bang for the buck upgrades out there!

Happy modding!

Just put a 17mm on today of a firend's wrx. Car handles so much flatter now. I would say it allows to close to 10-15% increase in cornering speeds for my personal driving. Car feels a tad more tight over rough stough, but barely noticeable.

Two thumbs UP!

When I went to go get winter tires, I removed the RE-92's, and never put them back on. The winter tires went on the steelies, and the car did roll alot, but we are talking the factory size (195-60-15) which is not exactly a low profile tire

After the winter, I bought 16x7's and BFGoodrich G-Force Sports(205-50-16) and what a difference that made. What I was taking at 40mph was now 45mph. Now with the rear swaybar (went from 13mm to 17mm), there is very little roll and I am able to point the car where i want it to go.

Going to be interesting to see what kind of a difference the rsb made on the winter tires...

Since we're bragging about our new stock sway deals.. i picked up a 20mm '02 RSB for my '05 RS. Yes, big improvement - I hope going for the 20mm over the 17 wasn't a mistake. It does require much more care and attention than standard 13mm.

1) I see some are afraid of the 20.. i wonder why - when many upgrade to 24+ aftermarket bars.

2) Will upgrading to metal endlinks have a material effect on handling? Isn't this only needed for the aftermarket larger-sized bars (for safety).

3) I purchased my RSB without the rubber bushings ! This created a problem of course because the ones meant for the 13mm will not fit.. I thought about cutting the rubber.. decided against it. Instead, worked out a temp fix: Rolled stips of cloth tightly around the bar, then electrical tape, and then fit the metal piece around this; made sure it was a tight fit and bolted it on.. Seems to be okay! after tonight's drive it does have some give when i get under there and push up on the bar.. Anyone have strong feelings against this? It is basically doing the same job as the rubber - I'll call around to see where I might be able to get the actual bushings tomorrow.

On a stock suspension, 20mm can feel like a lot. Upgraded suspension? 20mm, definitely.

I'm looking at the 20mm bar from subarugenuineparts.com, as it's cheaper than the 18mm and only a buck more than the 17mm. But I plan to install it, some STi pink springs, and a front sway bar all at the same time. I think by doing both front and rear bars at the same time will keep the car more balanced. If I was leaving the front sway bar stock, I'd do 17 or 18mm.

You might save about $50 if you buy used. can be found in the for-sale forums.. They came stock on the '02 wrx.. so do a search for "02 rear sway bar". Just make sure it comes with the rubber bushings... You don't need the '02 endlinks with the bar.. they are the same (plastic).

What front bar are you getting?

I received this front bar recommendation:
"The 22mm front Whiteline swaybar is part# BSF10 will fit the GD chassis 2.5RS."

i'm leaving the 19mm stock front and keeping my new 20mm rear. FYI- anyone using a '02 wrx RSB on their '05 RS will need to get rubber bushings that will fit on the 05 with a 20mm bar (luckily the part was in stock at my dealership - use the '05 sti bushings).

Bump for more input on your 17mm experiences. Maybe someone dealing with a stock L suspension.

I've got a 99 OBS that I swapped the 13mm bar for my old Wagon's 17 mm...stock suspension...rear hangs out a but more on slippery corners/heavy throtle in corners, but overall, feels more planted, sticks and pulls through like I wanted. Nice upgrade for the low, low price of free.
