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.
GENUINE MAZDA OEM Intake Solenoid for Mazda RX8 (Series 1 & 2, 2003-2012)
Happy 8's day people! For you series 2 owners, here's the easiest way I found to change these little suckers. RX8 Upgrades providing the genuine goods as always. Remove the air box/ CAI, remove throttle body and remove the top part of the UIM only, this will get you easy access to the solenoids. Now you could remove them from this point, but removing the oil filler neck along with the vacuum chamber the solenoids mount to makes it FAR easier to change them. This whole job can be done in an afternoon for a mechanically minded person. On reassemble, don't forget to place the vacuum reference back onto the bottom of the manifold (has a green check valve) otherwise no valve will work. Reassemble and enjoy. PN is KL01-18-741 for those chasing the part
HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)
I have the HKS Hi power, absolutely love it. It's much lighter than stock. Got a nice low tone at idle, reasonably quiet at 3.5k rpm around town and doesn't drone much on the highway. It's absolutely ignorant when you get to the redline with a satisfying "Pop POP" between gear changes. Has a unique sort of burble when the RPM's are coming back down.. You will love it too:)
Yes, I believe that's revision C. Racing Beat is a good store for Mazda's, I'd trust them when they say it's the real OEM coilset.
HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)
I had the hks hi power with ap midpipe and it was loud as hell but i loved it until i started getting pulled over all the time for it. You just have to keep the rpms down around the cops.
The 2003-2008 RX8 is a distinct car with its own fitment, calibration and quirks. Parts selected without that in mind can cause more problems than they solve. However, every listing here is relevant to the Series 1 platform, so you can shop with confidence that what you are looking at was engineered for your car. For Mazda RX8 Series 1 parts Australia-wide, this is the range built specifically around the early-model car.
For owners who want the car to operate exactly as Mazda intended, genuine OEM components are the straightforward answer. Factory-correct fit means no adaptation, no calibration guesswork and no compromise on finish or function.
In addition, a new genuine part removes the unknown history that comes with second-hand components. Worn seals, fatigued springs, or sensors that are borderline but not yet failed are all hidden risks. Meanwhile, genuine Series 1 supply from the original chain continues to narrow over time. Therefore, sourcing them new while stock exists is the practical move.
Not every job calls for a factory replacement. Moreover, aftermarket RX8 Series 1 parts chosen for the early-model car often address areas where the OEM design left room for improvement. Cooling capacity, ignition performance, intake flow and suspension feel are common targets.
The rotary engine is more sensitive than most to consistent oil quality, coolant temperature and strong ignition. As a result, targeted reliability upgrades in those systems pay dividends in long-term dependability. Also, the right aftermarket component, chosen for your car’s condition, can make the Series 1 feel sharper than it did from the factory.
Used consistently, this approach keeps the early-model RX8 doing what it was built to do. Because the right parts matter, it delivers an involving, high-revving driving experience over real kilometres. That is what sourcing the right Mazda RX8 Series 1 parts Australia-wide is ultimately about.
The RX8 Series 1 covers model years 2003 to 2008. If your car falls within that range, it is a Series 1 and the parts listed under this category are the ones to browse first.
Check the fitment details on each individual product listing before ordering. If your car has been modified from its original configuration, compare the listed part against your vehicle carefully, as aftermarket changes can affect compatibility.
Yes, genuine Mazda components are available within this range. A new genuine part gives you factory-correct fit, calibration and finish, and removes the uncertainty of unknown wear history that comes with used or sourced second-hand parts.
Genuine OEM parts restore factory operation and finish exactly as Mazda intended, making them the straightforward choice for standard replacements. Aftermarket parts suit owners looking to tailor driving feel, presentation or build direction beyond the factory specification, with the right choice depending on the component and how the car is used.
Not necessarily. Series 1 (2003-2008) and Series 2 (2009-2011) RX8 models differ in several areas, including sensors, body components and some mechanical parts. Always confirm the stated fitment on the individual product listing before purchasing.
Yes, this range includes both factory-style replacements and aftermarket components suited to a considered ownership approach. Addressing worn components alongside relevant upgrades at the same time is a practical way to support long-term Series 1 reliability.
Where practical, yes. Grouping related servicing or replacement work together saves labour time and avoids disturbing the same area of the car twice. The product listings can help you identify what else may be worth addressing at the same time.
