AUTOEXE Heptagon Wheel Nut Set for Mazda RX8 (Series 1 & 2, 2003-2012)

Seven-sided red lug nuts replace plain stock hardware with a sharp colour accent that sharpens every wheel centre.

RX8 heptagon wheel nut set fitted to silver Mazda alloy wheel with red caps

$190

The RX8 heptagon wheel nut set is a 20-piece fastener upgrade. It turns overlooked wheel hardware into a deliberate styling detail. Each nut is heptagonal in profile, chrome-vanadium steel in the body, and capped with an anodised aluminium top in AUTOEXE red. A special adapter is included, making installation straightforward. Fitment covers both Series 1 and Series 2 cars, M12-P1.5 thread pitch, at 32mm length.

RX8 Heptagon Wheel Nut Set Key Features

  • Seven-sided heptagon profile gives each wheel centre a sharp, recognisable geometry not found on standard lug nuts.
  • Bodies are chrome-vanadium steel, chosen for its strength and resistance to the torque cycles that wheel fasteners see in normal driving.
  • The anodised aluminium top cap carries the AUTOEXE logo in red. It creates a defined colour accent that lifts dark or silver wheel faces without requiring new rims.
  • At M12-P1.5 x 32mm, thread pitch and length match the RX8 hub spec directly. No modifications are needed beyond the supplied tool adapter.
  • Finally, the full set of 20 nuts covers all four wheels with matched hardware throughout, so no single wheel is left with an inconsistent fastener.

For RX8 enthusiasts building out an exterior detail story, the RX8 heptagon wheel nut set is a low-effort, high-visibility change. The red caps read clearly at a glance. They hold up against the anodising process rather than fading like painted alternatives. These are wheel nuts that earn their place on a restoration refresh or a finished show build alike.

The red accent pairs naturally with the LEG MOTORSPORT Anodized and UV Resistant Rear Window Button x2 (Red) to carry the colour theme into the rear quarter. For body-side contrast, the HASEPRO Carbon Side Decal Dress-Up Set (2) adds a darker graphic element that sits well alongside the red hardware.

Frequently Asked Questions

Do these wheel nuts fit both Series 1 and Series 2 RX8 models?

Yes, the AUTOEXE Heptagon Wheel Nut Set is designed to fit both Series 1 (2003-2008) and Series 2 (2009-2012) RX8 models. A single matched set covers either generation, so there is no need to specify your series when purchasing.

How many wheel nuts are included in the set?

The listing describes this as a full matched set intended to cover all four wheels consistently. Check the product listing for the exact count, as the number of nuts per wheel on the RX8 will determine the total quantity supplied.

What is a heptagon wheel nut and how does it differ from a standard lug nut?

A heptagon wheel nut has seven flat sides rather than the conventional six-sided hex profile. This gives each wheel centre a visually distinct, sharp-edged appearance that stands out from stock hardware, and it requires a matching socket for removal.

Are these locking wheel nuts that provide anti-theft protection?

No. The AUTOEXE Heptagon Wheel Nut Set is a styling accessory and is not sold as anti-theft or locking wheel hardware. If security is a priority, a dedicated locking nut set should be sourced separately.

Will the red finish hold up over time and resist fading?

The verified product details do not specify the coating type or durability rating for the red finish. For long-term care, avoid abrasive wheel cleaners directly on the nut surfaces and check with the supplier if you have concerns about finish longevity in your conditions.

Do I need a special socket to install or remove these nuts?

Because the heptagon profile has seven sides rather than the standard six, a conventional hex socket will not seat correctly. You will need a heptagon-compatible socket to install and remove these nuts safely without damaging the finish.

Will the red colour work with my wheel colour?

The red finish is described as creating a defined colour accent that stands out particularly against dark or silver wheel faces. Whether it suits your specific wheel colour is a matter of personal preference, but it is well suited to builds using red as a recurring exterior accent theme.
