GENUINE MAZDA OEM Floor Mat Set for Mazda RX8 (Series 1 & 2, 2003-2012)
Shout out to RX8 Upgrades for these awesome custom mats easy to deal with and good service
I am happy with the mod. Very happy. Taka s recommended first mod list: Sway bar. Odula intake or similar. Brake pads.
The AutoExe stuff is very nice--the leather is soft and rich, though the stitching isn't perfectly uniform. The AutoExe red stitching is a little brighter than the boot stitching and OEM stitching, but the difference isn't as big as it seems in the pictures. Overall, I'm very happy with this interior refresh. It feels like a new car.
OHLINS MAS-MI00S1 Road & Track Coilover Suspension for Mazda RX8 (Series 1 & 2, 2003-2012)
I use the Ohlins coilovers on my RX8, which is mainly used for street use and I found the standard spring rates to be too soft in the rear but the fronts to be fine. I changed my rear springs to about 350lbs/in and it feels pretty good to me now.
HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)
I say hks hi power (im a happy owner of it)
The rotary engine runs hot by nature. As a result, the cooling system earns its keep every time the RX8 climbs toward the redline. An RX8 aluminium radiator gives the system a meaningful upgrade over a tired original. For example, you get better heat rejection, lighter weight and a core built for hard sessions.
Mazda Australia specifies exact coolant system standards for the RX8. Meeting or exceeding those standards is the baseline for any cooling refresh. However, the radiator is only one part of the story. Hoses, thermostat and water pump components all work together. Because of this, replacing one worn item while leaving the others unchecked tends to come back around.
Before ordering, inspect the radiator, hoses, thermostat and water pump together. A failed hose on a freshly fitted radiator is avoidable. Therefore, catching it during the same job saves time and keeps the car out of trouble. Meanwhile, if the vehicle is already apart for engine work, a complete cooling refresh makes the most of the access you already have.
For owners sourcing RX8 cooling parts Australia-wide, the range here covers single-item replacements and full-system refreshes. Also, matching components to your car’s current configuration makes the setup easier to service next time.
Whether the goal is a like-for-like replacement or a more capable setup, correct installation remains essential. In addition, a fresh coolant service is always worth doing at the same time. The right combination of a quality aluminium rad, quality hoses and a properly rated thermostat keeps temperatures where they belong. Finally, that lets the rotary do what it was built to do, without the anxiety of watching the gauge.
The RX8 cooling range covers aluminium radiators, thermostats, coolant hoses and water-pump-related components. This lets you address a single known fault or carry out a broader cooling-system refresh depending on the condition of the car and the scope of your work.
An aluminium radiator offers better heat dissipation than the standard plastic-tank unit and is a common choice during a cooling-system refresh or when the original radiator is showing its age. It also suits owners who want a more durable core as part of a considered build.
It is worth inspecting the hoses, thermostat and water-pump components whenever the radiator is out, because access is much easier with the front of the engine bay clear. Replacing worn ancillaries at the same time avoids pulling everything apart again shortly after.
A lower-temperature or racing thermostat opens earlier, allowing coolant to circulate sooner and keeping operating temperatures lower under harder use. It is best planned as part of a properly considered cooling refresh rather than fitted in isolation.
Original RX8 coolant hoses can harden, crack or swell with age and heat cycles. If the hoses feel stiff, show surface cracking or the car has covered significant mileage on its original plumbing, replacement is worth doing alongside other cooling work to avoid a future leak.
Fitment varies by component. Each product listing confirms which series it suits, so check the individual part before ordering to make sure it matches your specific RX8.
A single replacement is perfectly reasonable when there is a known fault and the rest of the system is in good condition. A broader refresh makes more sense when multiple components are showing their age, or when the car is already partly disassembled for other work.
