Question 1

What parts are covered under the RX8 driveline category?

Accepted Answer

The driveline category covers components that transmit power from the gearbox to the wheels, including clutch kits, flywheels, differential parts, driveshafts, and propeller shaft components. These are the parts most directly responsible for how the RX8 puts its power down and how the drivetrain feels under load.

Question 2

How do I know when my RX8 clutch needs replacing?

Accepted Answer

Common signs include clutch slip under hard acceleration, a higher-than-usual biting point, judder on take-off, or difficulty selecting gears. The RX8's relatively high-revving rotary engine can accelerate clutch wear if the car is driven enthusiastically, so it pays to inspect the clutch alongside any gearbox or flywheel work.

Question 3

Is it worth upgrading the flywheel at the same time as the clutch?

Accepted Answer

Yes, and most experienced RX8 owners recommend doing both together. Replacing the flywheel while the clutch is already out adds minimal extra labour and gives you a known-condition friction surface. A lightened flywheel also sharpens throttle response and improves the rotary's natural revving character.

Question 4

Will a performance clutch kit make my RX8 harder to drive around town?

Accepted Answer

It depends on the clutch spec. Entry-level uprated clutches designed for mild performance use typically retain a pedal weight and engagement feel close to standard, making them suitable for daily driving. Higher-clamping stage kits aimed at track or heavily modified cars can have a heavier pedal and a more abrupt bite point.

Question 5

Can driveline work be done at home, or does it need a workshop?

Accepted Answer

Clutch and flywheel replacement requires the gearbox to be removed, which is achievable for an experienced home mechanic with the right tools, including a transmission jack and flywheel locking tool. Differential or driveshaft work is generally more straightforward, though all driveline jobs benefit from a torque wrench and access to a lift or solid axle stands.

Question 6

Does the RX8 have a limited-slip differential option?

Accepted Answer

The RX8 was offered with a Torsen limited-slip differential on certain factory specifications, and aftermarket LSD units are available for cars that left the factory with an open differential. Fitting an LSD improves traction out of corners and reduces inside-wheel spin under power, which is particularly noticeable on a rear-wheel-drive car used on track or driven on wet roads.

Question 7

Are there driveline differences between Series 1 and Series 2 RX8 models I should be aware of?

Accepted Answer

Some driveline components, including clutch and flywheel specifications, differ between Series 1 and Series 2 cars, and between manual and automatic transmission models. Always confirm the correct part for your specific series and transmission type before ordering, as an incorrect fitment can cause installation problems or premature wear.

Question 8

How often should RX8 driveshafts and CV joints be inspected?

Accepted Answer

CV boots should be checked at every service for cracking, splitting or grease leakage. A torn boot allows dirt and water into the joint, accelerating wear significantly. Clicking or clunking sounds during tight low-speed turns are a reliable indicator that a CV joint has already been running without adequate lubrication and may need replacement.
