Worth the upgrade
My car is 2011 wrx stage 2. I do some HPDE while i was on stock suspension. I will be bringing this to the track this weekend so hopefully i will have a better review. I installed the rear can definitely feel the difference in the rear being stiffer. I still felt there was a little roll in the front. Of course after putting in the front. The car felt more stabilized. You can enter corners with confidence and the steering responds much more that you expect it to be. The front sway is the same as Eibach. Just branded as RCE. It even says Eibach on it.

Just bought and installed these with a set of KB end links. I bought them after the RCE yellows. Fantastic addition to the car. Plants the wheels on the ground very well. Much lighter than others being hollow. A must have!

Worth the price!

I ordered these bars while they were out of stock and it was worth the 2 month wait! RSD kept me informed about the ETA of my order, a plus for customer service! I bought these sway bars over a set of Whiteline as I got the chance to autocross with a friend's WRX with these installed and fell in love with how well they felt. The sway bars kept the car flat through the corners and helped reduce much of the understeer from the stock setup. When I installed these to my own STI, I felt the same composure as my friend's car. Flat cornering and minimal understeer. I have it set to have a soft front/hard rear. The setup made the car more oversteer with the stock strut/RCE black springs. I enjoy driving my car again! I highly recommend these sway bars!

installing with the spt exhaust

The install was smooth. What I did was removed the two bolts on the muffler section then slide that towards the bumper. This will make putting in the rear section simple. I didn't have contact issues with the exhaust. I was surprised at how much clearance I had actually. As for the product. amazing going from stock to this is night and day. Don't cut corners and buy new end links. I have a 2014 sti hatch.

  • Q: 2011-2014 WRX SPT Exhaust Clarification  KHP 1 year ago


    It was mentioned that there's a clearance problem with the STi SPT exhaust. Does the rear sway bar also have a clearance issue with the 2011-14 WRX SPT exhaust? It seems like the 2011-14 WRX have the same exhaust system as the STi SPT quad exit exhaust.

    • A: The fitment issue would likely carry over to the WRX as well. The SPT exhausts for both cars should be the same.

  • Q: Equivalency of hollow to solid?  JonnyMuck 1 year ago


    What is a straight comparison of a solid bar vs. the 25.5 mm hollow bar? I am looking to compare this against other 22mm solid sway bars on my 2013 WRX STI Hatch. Thanks!

    • A: Unfortunately there is no exact equivalent between the two, a hollow bar is considered to be a couple sizes softer than a similar solid bar, so something like a 25.5mm is likely to be close to a 23.5mm in feel but this is a very loose rule of thumb.

  • Q: will this clear   DJHR 2 years ago


    the tomei Ti cat back?

    • A: They should clear that exhaust just fine, but we are not able to guarantee it since we have not tested fitment between the two parts.

  • Q: Settings   410scooter 2 years ago


    Which adjustments on the front sway bar are for the hard setting and soft setting? Thanks.

    • A: The stiffer setting is closer to the bend near where the swaybar mounts to the vehicle.

      Nick S. 2 years ago
    • A: As Nick stated, the hole closer to the bend is the stiffer setting. -Larry

    Will it fit with a q300?
