Whiteline's 2 hole 24mm adjustable sway bar allows trimming of oversteer/understeer through varying the sway bars ability to resist weight transfer via increasing or decreasing the effective arm length of the sway bars mounting position. If desired you can even set one side at the "hardest" position and set the other side a the "softest" position to achieve your desired effects.

A bigger front sway bar will give the car more understeer where a bigger rear bar will give the car more oversteer.

Love it!

I installed the rear bar last year shortly before my car broke down, and bought this front one once I got back on the road. I drove it long enough with the factory front to tell that this one is a vast improvement. Steering effort is greatly reduced (on the strongest setting BTW) and turn in a helluva lot sharper!

Improved handling but not a perfect product

I thought I loved these swaybar but they have been more of a headache. After driving and hearing a slight clicking noise I took these to my local performance shop and that is when we discovered the bar was bent hitting the control arm. If it weren't for this issue I would be happy with them. Apparently they have a history of being bent I thought that was rectified.

awesome upgrade

installed this sway bar along with kartbot endlinks F & R, with 22mm rear bar with the whiteline rear brace bars, and soon after did a canyon run, and the car responded way better then it has before, really be able to brake later and take turns more aggressive

Combined with a 24mm rear, driving through corners or turns have become more grounded and less sloppy. There's still body roll but that's probably due to the seat bolstering. Overall, I love this product.

Whiteline 24mm swaybar

I'm running this 24mm swaybar up front and rear with Kartboy endlinks on my 14 WRX sedan and it is amazing! The overall stiffness and reduction in body roll are very noticeable over the stock setup and it gives the car a more aggressive feel without sacrificing ride comfort. You will need some spacers with this swaybar when bolting it to the endlinks. A must have for anyone looking to beef up their suspension to make their ride more intoxicating


  • AnswerQ: effective diameter  duder 12 months ago

    What is the effective diameter for the two holes? 23mm/24mm? 24mm/25?

    • A: You're correct. The middle setting will reflect the 24mm setting where the other two settings are +/- 1mm. Thank you.

  • AnswerQ: Soft or hard adjustment  relier1 1 year ago

    So I can't find any documentation on which of the two holes is the soft or hard adjustment?

    • A: The stiff setting will be the hole closest to the bar itself, which is the front hole when the bar is installed.

  • AnswerQ: rubbing issue  johnathan d 2 years ago

    Installed the 24mm with kartboy endlinks and spacers, the sway bar is hitting the steering linkage when the wheels are fully turned either left or right. When the car is sitting with the wheels straight its fine. Installed with loaded suspension. Set on soft setting, I think. What is happening? How can I fix

    • A: From what you are explaining, it sounds like the sway bar may have been installed upside down, which is not uncommon. Please contact us for further assistance.

    • A: That is not included, just reason being is you use all factory torque specs same as the Subaru Factory Service Manual
