Whiteline ARBs (Anti Roll Bars - Sway Bars)

Jump to   Impreza   Forester   Legacy   Outback

Whiteline Sway bars (anti roll bars - ARBs) come with the necessary chassis D bushings. These  bars  are  made  of  high  tensile   solid  steel  that  offer up to 3  way adjustability
(Z suffix part numbers) to fine tune your Subaru suspension to your liking !!

Adding a stiffer rear swaybar helps to rid your Subaru of it's inherent understeer problem!! Corner turn-in is noticeably faster with much better transient response.

If you uprate the front suspension then it is recommended to further uprate the rear suspension. Example, uprate the rear suspension to 22mm Whiteline ARB and you reduce understeer and increase turn in. Uprate the front ARB and you will increase understeer unless you either uprate the rear to 24mm or set the adjustable front ARB (where blade adjustable front ARB is available) to soft and set the adjustable rear ARB (where blade adjustable ARB is available) to hard setting. We recommend adjustable front and rear Whiteline antiroll swaybars.

We do recommend upgrading your swaybar mounts when you upgrade with the stiffer rear bars marked with *1 in the lists below

BEGINNER Whiteline sway bar guide to better handling:

Front Wheel Drive
Increase the rear sway bar size to neutralise understeer.

Rear Wheel Drive
Increase the front sway bar size to neutralise oversteer.

All Wheel Drive
Increase rear then front bar size to fine tune handling behaviour.

4 Wheel Drive
Increase front then rear bar size to neutralise understeer.

Whiteline Swaybar Stiffness Calculator (Size Caculator)
Whiteline Sway Bar Stiffness Calculator

Fixed Bars: Choose original bar diameter from left column, then follow across to the right to determine % increase in stiffness required. Or, check % stiffness of a new bar size against the original.Example - Upgrading from a 16mm factory sway bar to a 20mm Whiteline way bar equates to a 144% increase in torsion rigidity (Refer red highlight in chart)

Adjustable Whiteline Swaybars:
Choose original bar diameter from left column, then follow across to the right to advertised Whiteline bar size and based on points of adjustment;

2 point adjustable - simply add 1mm for extra (stiffer) hole position.
Example - Upgrading from an 18mm factory bar to a Whiteline 22mm 2 point adjustable sway bar results in a 123% (soft) and 167% (hard) increase in torsion rigidity. (Refer blue highlight in chart).

3 point adjustable - simply subtract 1mm for soft setting and add 1mm for hard setting. Example - Upgrading from a 20mm factory bar to a Whiteline 24mm 3 point adjustable sway bar results in a 75% (soft), 107% (standard) and 144% (hard) increase in torsion rigidity. (Refer green highlight in chart).

4 point adjustable - simply subtract 1mm for soft setting, add 1mm for intermediate setting and an additional 1mm for hard setting. Example - Upgrading from a 22mm factory bar to a Whiteline 26mm 4 point adjustable sway bar results in a 67% (soft), 95% (standard), 127% (intermediate) and 162% (hard) increase in torsion rigidity. (Refer orange highlight in chart).

Heavy Duty Swaybar Mounts recommended with this bar
Note - we are not pushy sales oriented people, however with respect to significantly larger rear swaybars, the forces you exert on your stock swaybar mounts with these much larger bars is more than Subaru originally engineered the mounts to withstand. Therefore we do recommend upgrading your swaybar mounts when you upgrade with the stiffer rear bars.
