Whiteline 02-06 Acura RSX Type S DC5 Rear 24mm Heavy Duty Adjustable Swaybar

Whiteline 24mm Heavy Duty Blade Adjustable Rear Sway Bar — Acura RSX / Honda Civic (BHR67Z)

The rear bar, and on a front-drive Honda this is the one that changes how the car actually behaves.

Why the rear bar matters on a FWD chassis. The DC5 is naturally biased toward understeer, and the factory rear bar doesn't do enough to counteract that once the car moves past stock. Adding rear bar shifts load balance rearward, which frees the front wheels to grip and steer. The result is sharper turn-in and a rear end that follows the front instead of lagging behind it.

If you've already added stickier tires or stiffer springs and the car still pushes wide on corner exit, the stock rear bar is almost always the bottleneck.

Two-point blade adjustable — two end link positions per side. Changing which hole you use changes the lever arm length and effective stiffness at the wheel, so you can tune the balance without buying another bar.

Solid steel, not hollow. Whiteline doesn't hollow their bars to save material cost the way some manufacturers do. Includes polyurethane mounting bushings and lateral locks that prevent the bar shifting sideways under cornering load.

The honest trade-off: more rear bar makes the car rotate more easily. Great for turn-in, less ideal in the wet on a daily driver — which is exactly what the adjustment is for. Soften it back down for winter.

Fitment: 2002-2006 Acura RSX, base and Type-S — both share the same rear subframe and mounting points. Also 2001-2005 Honda Civic.

Install guide included. 3 year warranty.

Pairs with the front bar (BHF50Z) if you want to control roll at both ends rather than just shifting balance.
