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.
The bars are out of this world. At first when I saw the picture on the autoexe catoluge they look small but in person the bars are huge. Similar to the Cusco design of hollow strut bars these autoexe bars are the same, having a hollow design. The autoexe kit also came with an authentic serial code and were carefully designed to fit with no problems. The front lower arm bar is very strong made out of steel and hollow inside. The front lower arm bar attaches onto the lower arm and onto the frame. In a X Brace member design. Unlike the cusco bar and the mazdaspeed the Autoexe lower arm bar is pinched between the lower arm and the chassis. With each ends conected to the two bolts of the lower arm. (Hard to describe but look at the pics) The rest of the bar connects onto the frame. There is a small kit that wedges/attaches itself onto the frame without drilling anything. The bar is also slanted on the right side for the header/downpipe. Overall I'm very happy with the bars. The quality of the autoexe bars are excellant and the packaging and handling of the bars are superb. I found my turn in using the autoexe bar was more responsive then my old Cusco lower arm. As well my rear is more stable when exiting out of corners. The best part about these bars is probably the front member brace and the triangualar rear brace that strengthen up the chassis. Because with my current suspension setup to the max and without my roll cage installed yet, my cars chassis is flexing from the pressure and stress buildup that I put on it at the track. For the price I'm very satisfied. Even though the price isn't cheap and in some cases you can buy a car, but the bars are definatley worth the money.
Trip from Sunshine Coast to Gold Coast was a blast ! Car feels so much better, so much more throttle response, so much cooler.

I got the authentic R Magic lip one and they are sexy! The bigger one is growing on me.
Drivetrain fluid condition matters more than many RX8 owners realise. The differential and gearbox work hard in a rear-wheel-drive sports car. As a result, degraded or incorrect lubricant shows up as notchy shifts, increased wear, and inconsistent feel at the limit. FORTEC covers both applications with purpose-graded oils, including RX8 80W-140 differential oil for the rear diff.
The differential and gearbox are separate systems with different fluid requirements. For example, treating them as interchangeable is one of the more common drivetrain servicing mistakes. The 80W-140 viscosity grade suits the load and temperature demands of the rear differential. Meanwhile, owners researching RX8 75W-90 gearbox oil are looking at a different job entirely. The lighter viscosity reflects the gearbox’s own design requirements.
This range brings together FORTEC’s lubricant line-up in one place. Therefore, compare options by grade before ordering. Whether you are planning a full drivetrain service or targeting a single component, review the available RX8 80W-140 differential oil and gearbox oil listings against your requirements.
Learn more about the full FORTEC Lubricants product range on the manufacturer’s official site. However, always check each product listing for application details. Also, use your RX8 service documentation to confirm suitability for your build.
The RX8 differential typically calls for an 80W-140 grade gear oil. Always cross-reference with your vehicle's service information to confirm the correct specification for your build and intended use before selecting a product.
No, the RX8 differential and gearbox are separate systems that use different fluids. The differential commonly takes an 80W-140 grade oil, while the gearbox is typically serviced with a 75W-90 grade. Selecting the right fluid for each component is essential - check each product listing's stated application before ordering.
Service intervals for the RX8 differential vary depending on use and driving conditions. Refer to your Mazda service documentation for the recommended interval, and factor in your intended use - for example, track use may warrant more frequent changes than regular road driving.
Yes, many RX8 owners plan both services together as part of a drivetrain maintenance session. Just treat them as two separate fluid choices - confirm the correct grade and application for each system individually rather than using the same oil across both.
Check the grade and application details on the individual product listing, then compare that against your RX8 service information. The key details to match are the viscosity grade and the intended application - differential versus gearbox - to make sure you are ordering the right fluid for the right component.
