The RX8 SE3P manual flywheel from AUTOEXE is a fully machined chromoly steel upgrade. It reduces rotating mass from the OEM 7.6 kg down to 5.5 kg, a 28% reduction in moment of inertia. That figure translates directly into a Renesis that changes engine speed more readily on every input. Designed specifically for the SE3P platform, it targets street drivers who want genuine drivetrain feel without sacrificing day-to-day drivability.
For rotary enthusiasts who heel-and-toe regularly, this SE3P manual flywheel shows its value most clearly on the downshift. Blipping the throttle to match revs feels crisper. The engine responds to the blip and settles more quickly, making the whole action more deliberate.
At the top of the rev range, reduced rotating mass lets the Renesis climb and fall with less reluctance. That amplifies the naturally free-revving rotary character that makes the SE3P rewarding to drive hard.
When the flywheel is out, the clutch friction surfaces are already exposed, making it the logical moment to renew the full clutch assembly. The AUTOEXE Intake Suction Kit complements this RX8 SE3P manual flywheel upgrade by sharpening throttle pickup from the intake side, so the engine responds just as eagerly to the accelerator as the lighter rotating assembly allows.
While the drivetrain is apart, fitting the R-MAGIC Super Magnetic Gearbox Drain Plug is a straightforward reliability addition that captures fine metal particles in the gearbox oil on every drain interval.

Yes, the AUTOEXE sports flywheel fits all manual RX8 drivetrains across the full 2003-2012 production run, covering both Series 1 (2003-2008) and Series 2 (2009-2012) cars.
Yes, the AUTOEXE sports flywheel is a manual-transmission upgrade only. Automatic RX8 variants do not use a conventional flywheel in the same way and are not compatible.
Reduced rotational mass means the Renesis changes engine speed more readily in response to throttle inputs. The engine revs up and drops back down with less inertia, making every throttle input feel more direct and rev-matching on downshifts noticeably crisper.
The benefit is most obvious whenever you are actively matching revs during gear changes, particularly on downshifts using heel-and-toe technique. On the street this translates to a more responsive, engaging feel; it is not purely a track-day item.
It makes strong sense to do so, since both components are accessed in the same job. The AUTOEXE Sports Clutch Kit is the natural companion to this flywheel, matching its performance intent and allowing all friction-surface work to be completed in a single strip-down.
Fresh gearbox oil is a worthwhile addition while the drivetrain is already disassembled. The CUSCO Super Sports Gearbox Oil with Neo 2L is a quality choice that pairs well with this upgrade.
