Understeer Compensation...

Well, I am well aware of what a sway bar does, and I'm also somewhat in tune with all the movement going on in the chassis while hitting turns and such. I want to improve handling all around and rid some if not all of the understeer in the process. I can't buy everything all at once so I'm looking at lining things up in a strategic manner for purchase. My options have been narrowed to the Front Strut Tower Brace or Rear Sway Bar and End Links for the first purchase. It's a little confusing as to how much effect I will see with either by itself and I won't be getting the front sway for a bit yet.

So what would be the better first pick of the two (even though the rear sway and end links count as one and will be significantly more expensive than the strut tower brace). I'm leaning towards the strut brace along with the stiffer transmission mount...

Any input and experience would be greatly appreciated on this! Thanks and Happy New Year!

From the reaing and research I have done, the way the EJ engines are built and placed in the engine bay you really dont get much from a strut bar, at least on a daily driver. For better handling and getting rid of the factory understeer a nice (adjustable) swaybar and good enlinks are the way to go. Idk if anyone else can back that up. But I know that throwing on some tranny mounts are a really nice upgrade also. But if I were you (and Im kind of in your situation) I would go with the sways first.

Sways and endlinks for sure, you will notice a HUGE difference.

Excellent feed back guys, thanks! I heard the same from a guy who wanted to sell me shizz so I had to check with 'the crew' first and make sure of what's really going to be the most effective. I definitely know there's alot of slop in the body roll of the WRX model and I just don't know the car well enough to pin point it, but had the idea that the rear sway would isolate a good bit of it. So rear sway and end links first (well the tranny mount is a heck of alot cheaper so that might squeak in first, but I need my buddy to help mount that piece). It does seem like the strut brace would do some good up front though, just no where near what I'm getting the sway will do in the rear. SOLD! So with that in check, any experience with comparing the Whiteline, Perrin, Cobb, ect. bars? it seems they all come with the polyurethane mount bushings, but are all different (i.e. hollow, solid, all kinds of bent, straight bar). I don't plan on hitting the track too much, but I do DRIVE the dang thing when I can let loose from the herd I personally have been close on Whiteline and Perrin. Perrin is cheaper and looks quite nice since the older 'noisy' ones and have heard no complaints, but Whiteline has always put the quality out there without the bling so they say. Uncompromised. Thanks for all your help and feed back guys. It's a warm place to go when it's snowing outside

Both whiteline and perrin are good, but I would check rallitek for everything though, they arent as well known but I have ran 22mm rear sway whiteline and rallitek adj. and like the rallitek. They have awesome quality stuff, and the price is nicer on the wallet

Thanks Thack, those definitely look well made and the price is right for sure. I'm wondering though, since those are not adjustable I guess you're either happy with them or you'll get used to it eh? lol. If Perrin would make theirs in black or anything but red (even green, I mean why red everything?!) I would just grab that, but the Whiteline looks nice and professional and clean as well. The powdercoating is almost a must for something so close to the road imho. One ding and here comes the rust ya know. I guess it'll happen to any of them. I need mo' money and then I wouldn't even care to be so picky, lol. Thanks again though man, that's a good site to look at anyways. I'm always comparing =D

oh yeah, the one i have for my 03 is adj. so I would want that, from what Ive heard from other 08 09 owners, they like the rallitek endlinks paired with perrin bars, but I like whiteline much more. I have had good experiences with whiteline as well as perrin. Now it may be different for newer wrxs, but I once put a strut bar on my 03 and I could not feel a difference even when pushing it hard, i think they are more for looks and maybe some really pro drivers who are in-tune with their cars can tell the difference but its very small. for the front I would do a front sway, or h-brace to stiffen it up. theres also good tires to help if you dont already have those, just a thought

When shopping for sway bars, and consulting my shop their advice was to go as big as you can in the rear (but also making sure its adjustable) and the brands the recommended were Cobb, Hotchkis, and Whiteline. Pretty much in that order, and the endlinks the recommended were either the rallitek or the kartboy endlinks. I rode in 2 different STIs before, one with whiteline (kartboy endlinks), one with Cobb bars (rallitek endlinks). I honestly couldnt feel the difference in just riding, but I knew that both cars rode and handlen much better than my stock setup.

Also, if you're don't want to spend 5-600 on both front and rear bars and endlinks start off with just the rear bar and links. Basically the bigger the bar in the rear and the smaller the bar in the front, the more understeer you take out of the ride. Personally, I have the 25mm front bar and 22mm rear bar from Perrin. Front bar is on the "soft" setting, rear bar is in the middle, and I feel pretty neutral/slight oversteer. I'm thinking about cranking the rear bar up and see what happens now that I'm used to the feeling. WARNING: Get a feel for the way the car handles before you go taking turns at 50, it won't turn like you're used to and you can kill yourself.

Yeah, I'm really curious as to the change in feel this mod will provide and there's no way I would just go "it's all good I got a new rear sway" while taking a turn way over the limit (which I can do now for the most part with some solid confidence in feel of the car).

I have been eyeing the Whiteline bar the most now, but I can agree with Josh's tuner's advice that I don't want an adjustable end link. The Kartboy's seem to be the best that I've seen for clean and solid, since the Rallitek's look like the OEM ones with just a better weld and urethane bushings.

I didn't even think about looking for used stuff. Probably because I don't want any chance for failure and no warrany on the part I guess, but I certainly am always looking for a deal, lol.

i put a whiteline rear sway bar on my 09. it's a huge improvement!! you'll be a lot more confident in the corners. plus the sway bar came with two support bars, so that was a bonus. i've got mine set on the middle setting with stock endlinks, i'll upgrade those later on.

Be mindfull of Whiteline bars and KB endlinks.... Try to do a little research on bar/link combos. I'm not downing KB as I love their stuff.... Just look around. I recommend Perrin/Perrin... Or COBB/KB.....my .02.....

The rallitek endlinks are exactly like stock in theory, just ALOT beffier, and stronger material. Just a thought. I have seen them in person, and compared them to stock. ONe of my old friends participater in auto-x as much as he could with Cobb bars and rallitek endlinks (for at least 2 yrs that I knew him) and he never had an issue with them.
