CAR SHOP GLOW Passenger Footrest Plate (Aluminium) for Mazda RX8 (Series 1 & 2, 2003-2012) CAR SHOP GLOW Passenger Footrest Plate (Aluminium) for Mazda RX8 (Series 1 & 2, 2003-2012)

Well I broke down and bought this since I didn't want the girlfriend putting her feet up on the dash on long trips or when she can't sit still. This is still set up for the RHD cars, but with a little rigging you can get it to work. It took me about an hour to put in the illuminated shifter, and about 3 hours to figure this out and put it in place. I had to replace the bolts it came with sheet metal screws and a few lock washers, but its in. Its actually pretty comfortable, and I just hope it helps keep the feet off the dash.

AUTOEXE is a Japanese specialist with deep roots in Mazda development. Their range of RX8 aftermarket parts reflects that heritage at every level. Each component is designed around the RX8’s character rather than adapted from a generic catalogue. As a result, fitment, finish and the way pieces work together are all considered from the start. For owners in Australia looking to buy AUTOEXE upgrades, this range covers the three areas that define how an RX8 looks, handles and sounds.

Exterior Styling That Works as a System

AUTOEXE exterior components are designed to complement one another. Therefore, it is straightforward to build a cohesive look without mixing unrelated visual themes. An AUTOEXE front under spoiler sharpens the nose profile without looking aftermarket-aggressive. Meanwhile, an AUTOEXE RX8 rear cowl gives the tail a cleaner, more resolved finish. Combining these exterior pieces produces a result that reads as intentional.

Finally, if an AUTOEXE spoiler search for Australia has brought you here, review the individual listings for series compatibility, because some pieces are series-specific.

Chassis and Exhaust Upgrades

Beyond appearance, AUTOEXE addresses the feel and sound of the car with equal care. For example, an AUTOEXE RX8 strut brace adds measured rigidity to the front end. As a result, the chassis delivers a crisper, more connected feel through direction changes. It also does this without compromising everyday composure.

On the exhaust side, an AUTOEXE RX8 sports muffler refines the rotary’s distinctive note. It runs sharper and cleaner under load. Moreover, it avoids the antisocial volume that makes a modified exhaust tiresome on longer drives. In addition, these aftermarket upgrades change how the car feels and sounds every time you drive it, not just how it looks in a car park.

RX8 Aftermarket Parts from AUTOEXE, Why They Stand Apart

  • Mazda-specialist engineering: AUTOEXE develops products specifically around Mazda platforms. Therefore, RX8 fitment and calibration are considered from the start, not an afterthought.
  • Cohesive build potential: Exterior, chassis and exhaust components share a consistent design language. As a result, it is easier to build a car that feels deliberate.
  • Japanese manufacture: Parts are produced to Japanese quality standards. Also, finish and construction quality holds up over time and repeated use.
  • Genuine AUTOEXE for the RX8 in Australia: Purchasing through an authorised Australian retailer means you receive genuine components with correct specifications, not grey-market or unverified stock.

Before selecting RX8 aftermarket parts, consider your build priorities. For example, whether the main focus is exterior presentation, chassis feel or exhaust character, work outward from there. Individual product listings carry full specifications and series fitment details. However, visit the AUTOEXE official website for broader brand information and model history.

Frequently Asked Questions

What types of RX8 parts does AutoExe make?

AutoExe produces exterior styling components, chassis support parts and exhaust upgrades for the RX8. The range covers items such as front under spoilers, rear cowls, strut braces and sports mufflers, making it straightforward to build a cohesive car across multiple areas with components from the same manufacturer.

Are AutoExe parts a good fit for a themed or matched RX8 build?

AutoExe suits owners who want styling, chassis and exhaust components from a single brand with a consistent design language. Choosing multiple AutoExe parts helps avoid the mismatched look that can result from combining unrelated aftermarket pieces from different manufacturers.

Does AutoExe make both Series 1 and Series 2 RX8 parts?

Fitment varies by individual product, so check each listing carefully before purchasing. Some AutoExe components suit both series, while others are specific to one. The individual product pages confirm which RX8 variants each part is designed for.

What is AutoExe's background as a brand?

AutoExe is a Japanese aftermarket manufacturer with a long-standing focus on Mazda vehicles, including the RX8. For full brand and heritage information, the AutoExe official website at autoexe.co.jp is the primary reference.

How do I decide which AutoExe RX8 parts to buy first?

Start by identifying your main priority - whether that is exterior presentation, chassis feel or exhaust character. AutoExe components are designed to work well together, so knowing your build direction first helps you choose parts that complement each other rather than addressing unrelated areas at once.

Will an AutoExe strut brace work alongside my existing RX8 suspension setup?

An AutoExe strut brace is generally designed to complement the existing suspension rather than replace it, adding rigidity to the front strut towers. Review the individual product listing to confirm compatibility with your specific RX8 configuration and any suspension modifications already fitted.

Is the AutoExe sports muffler a direct bolt-on for the RX8?

AutoExe sports mufflers are designed to fit the RX8 exhaust system, but always confirm fitment on the specific product listing as compatibility can vary between Series 1 and Series 2 vehicles. Check the listing details before purchasing to ensure it suits your car's configuration.
