AASCO Lightweight Steel Flywheel & Sachs Performance Clutch Kit – Porsche 987.2 Boxster (S) / Cayman (S) / R / Spyder Manual 2009-2012
Part Number: 106428-12-PKG
Brand: AASCO Motorsports
Upgrade your manual Porsche 987.2 Boxster or Cayman with a complete AASCO lightweight steel flywheel and Sachs Performance clutch package designed to reduce rotating mass, dramatically improve engine response, and refresh the clutch system at the same time. This kit pairs an AASCO 18 lb lightweight steel flywheel with compatible Sachs Performance clutch components for select Porsche 987.2 Boxster and Cayman manual applications.
Compared to the heavier factory 27 lb dual-mass flywheel setup, the AASCO lightweight steel flywheel removes roughly 9 lb of rotating mass compared to the factory flywheel. The result is an engine that revs more freely, responds more sharply, 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 987.2 Boxster or 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 987.2 Boxster or Cayman 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 going to the lightest possible flywheel setup.

Matched flywheel and Sachs Performance clutch package
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 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 similar-looking lightweight flywheel and clutch options for the 987.2 Boxster / Cayman platform. The correct choice depends on your engine, pressure plate configuration, and whether you want the flywheel only or a complete clutch package.
This listing is for the AASCO 106428-12-PKG complete kit. It is the right choice if you want the AASCO lightweight steel flywheel, Sachs Performance pressure plate, Sachs Performance clutch disc, release bearing, and installation hardware together as a matched package for your compatible 987.2 Boxster or Cayman manual.
How This Differs From 106422-12
The 106422-12 listing is a flywheel-only option for select 987.2 Boxster / Cayman applications using the factory OEM pressure plate setup.
This 106428-12-PKG listing is a complete kit that includes the AASCO lightweight steel flywheel along with the Sachs Performance pressure plate, Sachs Performance clutch disc, release bearing, and required installation hardware.
If your car is keeping the factory OEM pressure plate and you only need the flywheel, use the correct flywheel-only listing.
If your clutch is worn, your pressure plate is worn or unknown, or you want to convert to the matched Sachs Performance clutch setup, choose this 106428-12-PKG complete kit.
Good Candidates for This Complete Kit
This complete kit is generally intended for:
987.2 Boxster 2.9L manual applications listed by AASCO
987.2 Boxster S 3.4L manual applications listed by AASCO
987.2 Boxster Spyder 3.4L manual applications listed by AASCO
987.2 Cayman 2.9L manual applications listed by AASCO
987.2 Cayman S 3.4L manual applications listed by AASCO
987.2 Cayman R 3.4L 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
If you already have a compatible clutch and pressure plate setup in good condition and only need the flywheel, choose the correct flywheel-only listing instead.
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
AASCO notes that 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.
Professional installation is recommended. However, there are DIY how-to guides linked below if you have the tools and equipment at home.
Important Notes
This listing is for the complete AASCO lightweight steel flywheel and Sachs Performance clutch package listed under part number 106428-12-PKG.
Fitment may depend on the vehicle’s model year, engine, transmission, and clutch / pressure plate configuration. Always confirm compatibility with your exact vehicle before ordering.
Before installation, compare the new flywheel, clutch, pressure plate, release bearing, and hardware to the original components being replaced.
Availability
AASCO Motorsports parts are specialty performance components. Although many items are available from stock, occasional delays may occur if an item is backordered or if AASCO is manufacturing a new batch. If there is a delay, we will provide an updated ETA before fulfillment.
