Stiffer Sway Bars?

[Rich10]

I love my 2011 V6 Genesis and think that it has a very comfortable ride, but I would prefer less body lean while cornering. Has anyone tried aftermarket sway bars, or maybe the V8 sway bars (which I think are stiffer)? Any downsides to doing this?

I'm on the same page as you Rich. I have the 4.6, but I was thinking about getting the R Spec sway bars to replace mine. Only 1 mm thicker than what's currently on the 4.6, so I have no idea if that would make too much of a difference, but it would give me something to tinker with this Spring Maybe you would want my sway bars??

EDIT - Just to be clear, the R Spec only has a thicker anti-sway bar in the rear. The front stays the same as the 4.6 model.

Just called my dealers parts department (Walser Hyundai in Brooklyn Park) and the rear anti-sway bar for the R Spec 5.0 is $154 and the bushings and straps are another $40, so Basically $200 for everything necessary to complete the job that I'm aware of. Sounds like I might head off to my parts department in another month

That probably will work.

Also keep in mind that the changes introduced in 2010 included:

• slightly softer springs
• slightly firmer shocks/struts
• beefier rear anti-sway bar.

There were some changes mid-year for 2009 that included the same 2010 rear anti-sway bar. I swapped out all the above components on my early 2009 for the 2010/2011 parts (no changes made in 2011) and it made a big difference. I have the V6, but the V8 changes were very similar (obviously different part numbers in most cases due to 200 extra pounds of the V8 up front).

Did it affect ride negatively? In the past suspension modifications that I've made to cars, stiffer sway bars haven't materially affected the car's ride. I need to resist the temptation to turn all of my cars into race ready cars and keep the Genesis as a luxury car.

Does anyone have a list of the swaybar thicknesses for the V6 and V8 Genesis sedans for 2009 - 2012?

My 2009 ride was significantly improved by upgrading to 2010/2011 specs (early 2009 was jittery and sometimes too harsh and out of control on rough roads). I made the same changes that were implemented on 2010. Keep in mind that the springs were softened in 2010, so slightly beefier anti-swaybar was not a problem. I would agree that simply adding a beefier anti-swaybar to a well-tuned suspension without other changes could be a problem. But the early 2009 had some issues, a few of which were fixed in mid-year 2009 and the rest fixed in 2010 model year. Hyundai made further changes in 2012 (similar to those made in 2010, such as softer springs, but better shocks to compensate for it).

You can look up the 2009-2011 sway bar parts here:

They don't have the 2012 parts catalog yet, but you can probably get info from your local Hyundai dealer. Also, the 2009 parts are probably mid-year parts and not the early 2009 parts.

Small update - Called my dealers parts department and spoke with a woman regarding what I'm looking for. She said she was new to Hyundai and needed to call HMA to find more info. the computer system shows the same part number for the 3.8, 4.6, and 5.0 according to the parts person. Currently waiting for her to call me back. She said a part like this would take 3 to 5 days to receive at the dealer. Looks pretty straightfoward on installation, and maybe I'll snap a few pics during install if I can get the correct part #. Anyone want to crawl under their R Spec and see if there is a part # listed on the rear sway bar?

Scott - Hyundai's documentation states the R-Spec's rear stabilizer bar is thicker than on the 3.8 and 4.6. It is 1mm thicker, I believe. If I weren't leaving for vacation in a couple of days, I'd let YOU crawl under my car and look for the part #. Better yet, you could drive my car and see if you liked the cornering behavior (unless, of course, you have already taken some fast corners in an R-Spec) and you'd let me hear what your Magnaflow setup sounds like from the inside of your car.

I should make an edit to my post - I know that the sway bars are different sizes (and part numbers) but for some reason the dealer's computer shows all being same part

Hopefully I will know more info tomorrow

I'd love to take a ride or drive in an R Spec to see what the difference is compared to mine, and I'm willing to bet you'd like my exhaust

I'll be back from Maui April 2 and will PM you. I'm in Prior Lake, but travel all over the metro pretty regularly.

Sounds good I should be taking my car out of storage soon (geez it's in the 70's already) Probably 1st or 2nd week of April.

I really wish someone would come out with suspension components for our cars... A nice set of CO's and new multilink components which would allow for a more aggressive stance as well as fully adjustable camber / toe etc

I have always ran my own alignment specs independent of the OEM. There is a potential market for this... as always 'if you build it they will come...'

I'm a little frustrated with my attempts to get information for an R Spec rear bar from the dealers. I have called a couple different dealers - 1 said he doesn't deal with part numbers over the phone and actually was a complete A**, and another dealer said the 3.8, 4.6, 5.0, and 5.0 R Spec all have the same size sway bars front and rear. WTF Also, I was advised a part number on the sway bar is unlikely and they come with a wire tag when ordered.

So how do we really know that the R Spec has a larger rear anti sway bar? Car and Driver and Motortrend mention this in a review of the R Spec, but Hyundai dealers' parts department seems to be in the dark.

EDIT - Just got off the phone with Hyundai customer service, and although they were very friendly and polite, they also didn't know anything about this and advised I recall the dealer. Perhaps the only way to confirm if the bar is different is to go to the dealer and measure the sway bar, and then measure mine.


EDIT #2 - Got a call back from my dealer (Walser Hyundai) and the woman was pretty helpful. She found that all Genesis models for 2012 do use the same exact anti-sway bar, which explains why the part is different vs. my 2009 part. She stated that any Genesis sedan built after April 2011 has this newer part. I will place me an order Found one at another dealer for $142

You can check part numbers here:
http://www.partswebsite.com/newhyundaiparts/?i=1&start=1&type=
I sent them an email a while back, and they said 2012 parts should be available on their site sometime in the spring (but not there yet).

Here is the page for 2011 rear stabilizer bars:
http://www.partswebsite.com/newhyun...id=10048&subcatid=20127&section=24&type=parts
You probably want the bushings and bracket, but not the link (I did not replace the link when I upgraded by 2009 suspension to 2010/2011 specs).

Thanks Mark. I think I did find this site a few days ago, but ran into the same issue you did with no 2012 parts listed yet. I will save the site to my favorites.

Just so you know, this is a regular Hyundai dealership in South Carolina (Hilton Head Hyundai). You call them on the phone or email them.

I'd be interested in knowing how the newer sway bar affects the ride. My 2009 could definitely benefit from a stiffer one.

As far parts websites, there are several out there that link to the same database of parts but it's been my experience that they don't necessarily match what the dealer's part database says.

They typically just used names like BRACKET-ASSY instead of an actual part number like you might find stamped on a part or on the label of the package it comes in. I recently went to my dealer to order some rear spring insulators. On the parts websites they call it an upper insulator but my dealer looked it up on his system and said they called it something else like a pad.

For the link I provided, it is a dealer (Hilton Head Hyundai in South Carolina). You can call or email them if you have a cconcern about specific part numbers. I replaced all four springs, four shocks/struts, and rear stablilizer bar for my early 2009 by ordering the parts from the above website, and having a local suspension shop change them out. Made a big improvement in the ride.
