Brand: AASCO Motorsports
Upgrade your manual Porsche 718 Boxster or 718 Cayman 2.0T with a complete AASCO lightweight steel flywheel and Sachs Performance clutch package designed to reduce rotating mass, improve engine response, and refresh the clutch system at the same time. This kit pairs an approximately 18 lb AASCO lightweight steel flywheel with compatible Sachs Performance clutch components for select Porsche 718 Cayman 2.0T manual applications.
Compared to the approximately 32 lb factory flywheel, this AASCO lightweight steel flywheel removes about 14 lb of rotating mass from the engine. The result is a sharper, more responsive engine that revs more freely, responds more directly, and feels more alive during downshifts, heel-toe shifting, and spirited driving.
At DasMotoring, this is one of our favorite upgrades for a manual Porsche. A lightweight flywheel can completely change the character of the car — making it feel sharper, more mechanical, and more connected. If your 718 Cayman has started to feel a little too slow or soulless, this is one of those upgrades that can reignite your love for the car and give it some of that 911 S/T-inspired character and flair.
We have run AASCO lightweight flywheels on our own manual Porsches for years through daily driving, traffic, backroad driving, and track use with excellent results.
This complete kit is a great choice for drivers looking for a more responsive, motorsport-inspired feel from their manual 718 Cayman 2.0T while also replacing the clutch, pressure plate, release bearing, and related hardware with a matched Sachs Performance clutch package. The AASCO flywheel is a lightweight steel design, which can be a nice balance for street-driven cars that want sharper response without moving to an ultra-aggressive race-style clutch setup.

Driving Feel
A lightweight flywheel reduces rotating mass at the engine, allowing the engine to gain and lose RPM more quickly. The result is a sharper, more immediate connection between your right foot, the engine, and the gearbox. Rev-matched downshifts feel cleaner, throttle blips feel more natural, and the car takes on a more responsive, motorsport-style personality.
Because the flywheel is significantly lighter than the factory dual-mass flywheel setup, some additional drivetrain noise, gear rollover sound, or chatter may be present. This is normal for many lightweight flywheel conversions and is part of the more mechanical driving experience.
The best way to minimize NVH and gearbox chatter is to avoid lugging the engine. Drivers should never lug the engine to begin with, and this is especially important with a lightweight flywheel. Keeping the engine above approximately 2,000 rpm, or selecting a lower gear when climbing hills or accelerating from low speed, will help keep the drivetrain happier and reduce unwanted chatter. The higher the rpm, the less drivetrain chatter and NVH you will have.
Which Version Should I Buy?
AASCO offers several lightweight flywheel and clutch options across the Porsche Boxster, Cayman, Carrera, Turbo, and GT platforms. The correct choice depends on your chassis, engine, transmission, and clutch package.
This listing is for the AASCO 106451-12-718-PKG complete kit. It is the right choice if you want the AASCO lightweight steel flywheel, Sachs Performance pressure plate, Sachs clutch disc, release bearing, and installation hardware together as a matched package for your compatible 718 Cayman 2.0T manual.
Complete Kit vs. Flywheel-Only
This is a complete flywheel and clutch package. It is the better choice if your clutch is worn, your pressure plate is worn or unknown, or you want the flywheel and clutch components matched together from the start.
A flywheel-only setup may be appropriate only if your car already has a compatible clutch and pressure plate configuration in good condition and you are specifically replacing only the flywheel. If you are unsure, contact us before ordering so we can help verify the correct AASCO option for your car.
Good Candidates for This Complete Kit
This complete kit is generally intended for:
Select Porsche 718 Cayman 2.0T manual applications listed by AASCO
Cars with a worn clutch, worn pressure plate, or unknown clutch service history
Cars converting from the factory dual-mass flywheel setup to an AASCO lightweight steel flywheel and Sachs Performance clutch setup
Drivers who want everything matched together as a complete AASCO / Sachs package
Drivers looking for sharper throttle response and a more mechanical feel from their manual 718 Cayman
If you are unsure which version you need, contact us with your year, model, engine, transmission, and current clutch setup so we can help point you toward the correct AASCO option.

Upgrade your manual Porsche 718 Cayman GT4, 718 Spyder, or 718 GTS 4.0 with an AASCO lightweight steel DFI flywheel designed to reduce rotating mass and dramatically improve engine response. This 14 lb lightweight steel flywheel replaces the heavier factory 28.5 lb dual-mass flywheel setup on compatible Porsche 718 4.0L manual applications, removing approximately 14.5 lb of rotating mass. The result is a sharper, more responsive engine that revs more freely, responds more directly, and feels more alive during downshifts, heel-toe shifting, and spirited driving.

Which Version Should I Buy?
AASCO offers several lightweight flywheel and clutch options across the Boxster, Cayman, Carrera, Turbo, and GT platforms. The correct choice depends on your chassis, engine, transmission, and clutch package.
This listing is for the AASCO 106447-12 flywheel only. It is the right choice if your compatible 718 4.0L manual already has a compatible clutch and pressure plate setup in good condition, or if you are replacing an existing AASCO 106447-12 flywheel and reusing compatible clutch components.
How This Differs From 106435-12-PKG
The 106435-12-PKG listing is the complete AASCO lightweight flywheel and Sachs Sport clutch package. It includes the AASCO 106447-12 flywheel along with the Sachs Sport pressure plate, Sachs clutch disc, release bearing, and required installation hardware.
Choose this 106447-12 flywheel-only listing if you only need the flywheel and your existing clutch and pressure plate setup is compatible and in good condition.
Choose the complete 106435-12-PKG kit if:
Your clutch is worn or due for replacement
Your pressure plate is worn, heat-spotted, damaged, or unknown
You want the flywheel, Sachs Sport pressure plate, clutch disc, release bearing, and hardware matched together as a complete package
You are converting from the factory dual-mass flywheel setup to a complete AASCO / Sachs Sport setup
Good Candidates for This Flywheel-Only Listing

Cars that already have a compatible clutch and pressure plate setup in good condition
Cars replacing an existing AASCO 106447-12 flywheel
Drivers who want the lightweight flywheel only rather than a complete clutch package
This flywheel is not intended for the 718 Cayman GT4 RS or 718 Spyder RS because those models are PDK-only.
If you are unsure which version you need, contact us with your year, model, engine, transmission, and current clutch setup so we can help point you toward the correct AASCO option.
Installation Notes
Professional installation is recommended. However, there are DIY how-to guides linked below if you have the tools and equipment at home.
If this flywheel is being installed with a Sachs Sport clutch disc, the larger portion of the clutch disc spring carrier must face toward the flywheel. If the clutch disc is installed backwards, the clutch diaphragm spring may contact the clutch disc, which can result in clutch failure and may not be covered under warranty.
Important Notes
This listing is for the AASCO lightweight steel DFI flywheel listed under part number 106447-12.
Clutch disc, pressure plate, release bearing, hardware, and related installation parts are not included unless specifically stated.
