Whiteline Rear Sway Bar - 24mm for Acura RSX 2002-2006

Whiteline 24mm Rear Sway Bar - 2-Position Adjustable | 2002-2006 Acura RSX DC5 / Type-S (BHR67Z)

If you want real RSX handling improvements, a rear bar is one of the first places to look. This Whiteline rear anti-sway bar ties the left and right rear suspension together through the factory chassis mounts and fights body roll by resisting one side compressing while the other droops. More rear roll stiffness changes how the rear tires share load in a corner, which directly changes balance.

On the DC5, the stock rear bar is usually the bottleneck once you add stickier tires, stiffer springs, or more aggressive alignment. This Whiteline 24mm sway bar steps up diameter and rate, so your car takes a set faster and feels less lazy in transitions. The trade off is simple: more rear bar makes the car rotate easier. Great for turn-in, not ideal if you drive in the rain like it's still July.

The Whiteline BHR67Z gives you two end link positions per side. Pick the inner or outer hole to change the lever arm length and effective stiffness at the wheel. That means you can tune the rear sway bar RSX setup without buying another bar. Go softer for daily duty and rough roads, go stiffer for autocross, track days, or if your current setup pushes like a shopping cart.

Who this is for

This bar is built for DC5 and Type-S owners who are pushing past street tires and stock springs. If you're running a street performance build, preparing for autocross, heading to an HPDE weekend, or chasing faster lap times at track days, this is the right upgrade. The adjustability means it works across all of those use cases without being locked into one setup. It also covers the full year range, so whether you need a sway bar for 2002 Acura RSX, a sway bar for 2005 Acura RSX, or the common 2006 RSX rear sway bar upgrade path, one part number handles all of it.

What changes behind the wheel

With the stock bar replaced, the rear end stops being the lazy half of the equation. You'll notice less understeer in medium and high-speed corners, flatter body positioning through transitions, and sharper response when you initiate a turn. On worn or mixed tires, the more even load distribution across the rear axle also helps with tire wear. The blade-type bar geometry gives you a more progressive rate response compared to a round-bar design of the same diameter, which means you get stiffness without sacrificing feel at the limit.

Whiteline engineering

Whiteline engineers suspension components specifically around the goal of activating more grip from the tires you already have. The BHR67Z uses blade-type bar construction, which is stiffer in torsion than a round bar of equivalent diameter while staying lighter. The polyurethane bushing inserts hold the bar tightly against the chassis without the deflection you get from rubber, so the rate you dial in is the rate you actually feel. This is the same approach Whiteline takes across their full Acura RSX parts lineup.

Selection considerations

This is the right call when a fixed-rate bar can't keep up with your setup, or when you know you'll be changing tires, spring rates, or alignment down the road. If you're shopping a 24mm sway bar for Acura RSX builds that need real tuning range rather than a one-size guess, this is it.
