From the Desk of Peter Partee, Partee Racing
Hello race fans! Today we’re covering the details on a product of ours that’s been a long time coming: our
lightweight flywheel and clutch kit for the BMW S62, specifically tailored for the E39 M5.
If you know me, you know I’ve spent way too much money and time testing just about every combination of clutch and flywheel under the sun — aluminum, steel, lightweight this, gimmick that. Unless you’re ready to spend $5,000–$6,000 on a full carbon setup (which, to be fair, is awesome if you have the budget),
this package is, hands down, the best overall clutch kit you can get for the S62 today. Here’s why.
The Flywheel: Lightened, the Right Way
What we’re using is a stock BMW dual-mass flywheel that’s been carefully lightened —
the right way.
We machine about
10 pounds off the perimeter, just like Dinan used to, just like some of the best aftermarket shops have done over the years.
What does that do? Simple:
- Reduces parasitic loss
- Makes the engine rev more freely
- Gives you sharper throttle response
- Makes rev-matching buttery smooth
It’s not just about taking weight off. We also machine the
inner circle to fine-tune balance and to make sure it meshes perfectly with the Sachs organic performance clutch we pair it with. Details matter.
The Clutch: Organic for Real-World Driveability
Why an organic performance clutch instead of some hardcore puck-style setup?
Because organic material can be slipped
.
You need that drivability — especially if you’re putting around town, doing daily duty, or hitting the occasional canyon run.
Sure, carbon clutches can slip too, but good luck finding one that doesn’t cost you a small fortune.
Our Sachs organic performance clutch gives you:
- Better heat tolerance than stock
- Higher torque capacity (tested up to 460whp on our NA builds)
- Stock-like feel — no nasty chatter or grabby behavior
The Pressure Plate: Heavy-Duty, But Still Streetable
Now, we pair that clutch with the
Sachs heavy-duty pressure plate — not so heavy you’ll need to hit the squat rack just to press the clutch, but heavy enough to handle serious power without turning your left leg into jelly.
It firms up pedal feel just enough to remind you you’re driving something special.
If you’re not a fan of adding pedal pressure, you could technically run it with a regular pressure plate. But for most of our customers, that slight bump in performance feel is exactly what they’re after.
Balanced to Perfection
There’s debate out there about whether you really need to balance the flywheel and clutch assembly together. In theory? Maybe not always.
But here at Partee Racing, we
balance every setup to within one gram.
If you can do it — and we can — why wouldn’t you?
Every kit ships with markings so you know exactly how to bolt it up and keep that perfect balance intact.
Who This Setup Is For
This clutch and flywheel package is ideal for:
- Naturally aspirated and lightly boosted S62s
- Builds making up to 600 wheel horsepower
- Owners who want faster revs, better clutch feel, and OEM-like driveability
If you’re pushing north of 600whp and planning to live there, you may want to look into a more aggressive twin- or triple-disc setup.
But for 95% of builds out there?
This is the perfect balance between performance, longevity, and daily usability.
Pricing and Ordering
The full kit — which includes the pre-machined lightweight flywheel, Sachs organic performance clutch, Sachs heavy-duty pressure plate, new spring and throwout bearing— is available now for
$2,350.

This is the kit is what I recommend to customers. If you’re looking to wake up your S62 without killing its everyday magic, this is it.
As always, thanks for your trust — and stay tuned for even more good stuff coming soon.
