Love my '14, but I'm moderately dissatisfied with the amount of body roll and handling slop in turns at moderate speed. This is my daily driver, and I'm not doing off-roading or racing, just moderately "aggressive" fun driving on my daily commute.

I've read about tires and sway bars, and I'm wondering if either/both of these would resolve the body roll issues.

Thoughts?

STi rear swaybar. Better tires will increase grip which will increase roll if no other mods are done.

 

[a.phoenicis]

That makes sense.

Will installing a sway bar impact (void) the vehicle warranty at all?

1+ on the STi sway bar! it's the best bang for the buck and most noticeable as well, it really changed the character of the car and made it more fun to drive. No, it won't void the warranty, it's just a stiffer sway bar than stock.

While bars will help some, they will not eliminate body roll. Try upgrading front and rear bars and see how you like it, there isn't a huge amount of options for the platform yet anyway.

The STI RSB was a great addition to ours. This is one of the first upgrades I make!

Performance tires also take a lot of the squishy-ness out cornering. It is a nice thing to do regardless of your other mods.

I'd say suspension is the best, but not the first/best bang for the buck.

I added the 19mm sti sway bar from my friends sti. But the Suspension really did it for me.

BCracings coilovers.

I upgraded my RSB and it's working out really well, I've played with it a few times since we've had some ice/snow in the area and I stay level. Not going very fast but she still handles nicely on dry/wet/ice/snow roads. Very east upgrade IMO you can check out what I did here toward the bottom... http://www.subaruforester.org/vbulletin/f115/sjs-sj-244914/

Probably going to do the RSB. A lot of people recommend it and my only complaint in the car is the little extra rear end kick and I think this will help a lot. Are you guys just ordering OEM or aftermarket? If so, where from?

 

[d2tharoc]

Suspension. Rsb helps with lateral roll, but if you are like me and can't stand having the nose pitch when you step on it stiffer springs are the only way. Subframe bolts are great too, howver i doubt the 14 has this issue?

 

[sooblover]

Stay with oem sti rsb if you are not doing other mods. Going too stiff (aftermarket) in the rear only would be spooky.

Feal 441 coilovers are much better in performance and value than BC. If you go this route, i suggest perrin 25mm front and 22mm rear adjustable bars. Front bar on soft and rear on hard will give you the best balance.
Ive autocrossed my fiances 2011 wrx (same suspension design/structure as you) with a very similar setup, so this advice is performance proven!

suspension is most effective.
Coilovers.. sway bars (F&R) and if they offer a front tower bar ?

 

[sway162]

Do you think I should upgrade the end links as well if I was to get the STi rsb?

 

[sooblover]

Maaaaybe. With the oem sti sway, your stock endlinks will likely be fine for quite a while... Upgrade if/when they wear out or start to clunk

While I concur on the RSB change, I've gotten cautious in my old age, having broken some sway bar parts at various times. IMO, if you're going to upgrade the RSB, you want to add the Whiteline braces (KBR15) to help support the body attachments. The price of the braces is way less than what repairing broken sway bar mounts will be.

I'll also note that while the STI bar is less expensive than the Whiteline 20mm bar, the Whiteline bar is available in an adjustable version. This means you can sneak up on exactly how much stiffer you want the rear. The STI bar has one setting.

 

[oempls]

^ Noted. Where can you find the whiteline rsb?

Search the internet. IIRC, the BSR49Z (adjustable 20 mm bar & braces) kit was around $200 from several suppliers. There were several suppliers as I recall. [supensionparts.com????? and others] Double check my part number. Searching for Whiteline suspension parts should get you their website.

 

[sooblover]

Im all for bracing but the kbr15 wont be necessary for an sti bar or 20mm bar, nothing will break, maybe a little flex.

Bigger than 20mm and/or lots of autox/track events with sticky tires? Yes, get the bracing for sure.

Can I please get the part# and year for the STI RSB you guys are talking about? Sounds like an easy upgrade that can be quite effective! Any pics too!? Thanks!
