What owners are saying

AUTOEXE Motion Control Beam Front and Rear for Mazda RX8 (Series 2, 2009-2012) AUTOEXE Motion Control Beam Front and Rear for Mazda RX8 (Series 2, 2009-2012)

Night and day difference, even on a bone stock suspension. While installing the AutoExe front strut bar greatly enhanced steering response and turn in, the handling improvements from it was very subtle. Likewise with the AutoExe tie bars installed in the front and back of the car. More solid feel, less suspension parts deflection under cornering loads. These Motion Control Beams took away the vibrations that are slightly felt in the steering wheel from small road surface imperfections. It also took away the bumps felt from pavement gaps and mostly the rumble felt from railway crossings and brick roads. Going through small pot holes and road patches, the stock suspension is finally doing its job to dampen away those bumps and doesn't get fully transmitted throughout the entire car. Big bumps, you don't hear a loud hollow "thump" emanating from the back of the car. Just a solid "thud". The car used to understeer and now it hardly does. It handles quite neutral now, even on bone stock open differential, and did I already say bone stock suspension? This is win win, all around, without sacrificing anything.

The RX8 arrives from the factory with a chassis that genuinely rewards development. Its near-50/50 weight distribution and low centre of gravity give you a strong platform to build on. The right Mazda RX8 handling upgrades let you sharpen what the engineers started. Whether you’re chasing more consistent steering feel on a favourite back road or building a purposeful track setup, your components should work as a cohesive system. Otherwise, mismatched parts end up pulling against each other.

Plan your suspension setup around the car’s balance

Effective chassis development starts with understanding what each part contributes to the whole. For example, springs and dampers set the baseline ride and body control. In addition, anti-roll bar hardware and adjustable end links let you tune the balance between front and rear grip.

Bushings, whether factory-replacement rubber or performance polyurethane, affect how cleanly inputs translate into actual movement. Worn factory bushings introduce vagueness that no spring rate change can fully correct. Therefore, addressing the fundamentals before layering on performance parts is always the smarter sequence.

The range here covers both genuine-spec replacements that restore the original calibration and purpose-built upgrade options for owners pushing the car harder. Both categories matter. A car with fresh, correctly-specced components behaves predictably.

Moreover, predictability is the foundation every RX8 handling improvement is built on. Mazda Australia remains the definitive reference for factory specifications and genuine parts information.

Build a balanced setup with the right combination

The most common handling mistake is fitting one component without considering how it changes the balance elsewhere. For example, stiffer springs without matched damper rates can make a car feel nervous. Also, uprated anti-roll bars without attention to the front-to-rear ratio can induce understeer in a previously neutral car. The suspension and chassis parts here are selected to suit the RX8’s specific geometry and weight distribution, chosen as considered Mazda RX8 handling upgrades rather than a collection of unrelated components. As a result, notes on each product help you understand where it fits in a wider build.

Where to start with RX8 handling upgrades

  • First, replace worn springs, dampers and mounts to restore consistent, predictable control before adding performance hardware.
  • Also, upgrade anti-roll bar components and end links to refine front-to-rear balance without compromising daily usability.
  • Then, choose polyurethane or OEM-spec bushings based on your priorities for road comfort versus sharp, direct response.
  • Finally, factor in a professional wheel alignment after any suspension change. Modified geometry without an alignment check wastes the potential of every part fitted.

Chassis hardware and how it completes the picture

RX8 chassis upgrades, including bracing and reinforced mounting points, are most effective when planned alongside the suspension package. The RX8’s body structure is a known quantity. Because of this, stiffening and support components work with the suspension to reduce flex and sharpen the relationship between steering input and corner response. As a result, the car feels more consistent under load, particularly in long, fast corners where chassis flex can mask otherwise good suspension tuning.

Parts for Australian roads and track use

Australia’s mix of smooth circuit tarmac, rough country roads and urban driving means a single rigid setup rarely suits all conditions. However, the range here includes components configured for a street-biased daily driver, a weekend road car or a dedicated track build. Selecting Mazda RX8 handling upgrades to match your specific driving priorities is what separates a genuine transformation from one that simply changes how the car feels.

Frequently Asked Questions

What handling upgrades make the biggest difference on an RX8?

The most impactful changes typically come from addressing worn suspension hardware first - degraded dampers, bushes and anti-roll bar links all erode the RX8's natural balance before any performance upgrade can work properly. From there, a coordinated package of springs, dampers and geometry-related hardware chosen to suit your driving style will deliver more consistent steering response and control than any single part fitted in isolation.

Should I upgrade suspension components all at once or one at a time on my RX8?

Coordinating component choices gives you a more balanced result. Fitting a performance spring without addressing worn dampers, or upgrading anti-roll bars without considering bushing condition, can create an uneven setup that works against you. Planning the combination around your driving goals and existing specification from the start avoids that outcome.

Are RX8 handling upgrades suitable for daily driving or only for track use?

The range covers both. Some components are well suited to refreshing a road car and restoring predictable, well-mannered behaviour, while others are better matched to a more purposeful weekend or track build. Ride quality, road conditions and how frequently you drive the car should guide which combination suits you.

Do I need a wheel alignment after fitting suspension parts to my RX8?

Yes. Any suspension work that alters ride height, replaces control arm bushes or changes geometry-related hardware should be followed by a professional wheel alignment. Skipping this step means the new components cannot perform as intended and tyre wear will suffer.

What chassis upgrades complement an RX8 suspension build?

Chassis upgrades are best treated as part of the same decision rather than a separate one. Coordinating chassis reinforcement and suspension component choices together helps you avoid an unbalanced setup and gives you a clearer path to the steering response and road manners you are aiming for.

How do I know which RX8 suspension parts are compatible with my existing setup?

Match new components to your current suspension specification, intended use and any modifications already fitted. If you are unsure which parts suit your build, the RX8 Upgrades team can help you work through the options before you buy.

Is it worth replacing factory RX8 suspension components even if they are not completely worn out?

Rubber bushes and dampers degrade gradually, so an RX8 that feels acceptable may still be well short of its potential once fresh components are fitted. Replacing ageing factory parts as part of a planned upgrade often reveals meaningful improvements in response and consistency that were being masked by the slow decline of the original parts.
