Product Information

Includes solid flywheel, pressure plate, clutch disc, throwout bearing, flywheel bolts, pressure plate bolts, and alignment tool

All newer BMW's come from the factory with dual mass flywheels for one reason: driving comfort. Due to the construction of dual mass flywheels, it is usually impossible to machine them if they are warped. Replacing a dual mass flywheel is also very expensive and in our opinion, ultimately not worth it if a solid mass flywheel is available.

This solid mass flywheel conversion kit from Valeo comes with all the major components you need to install a new clutch, flywheel, throwout bearing, and pressure plate. The solid mass flywheel offers greater durability with little to no compromise in driving comfort.

For service kit please see Valeo part number 828484. This flywheel cannot be used with a standard self adjusting clutch kit.

SMF upgrade
Am yet to install this clutch but its as I ordered with all the needed hardware and proper throw out bearing. Am writing this before install to note that I did receive a clutch alignment tool while others in the reviews claimed they did not. Am not sure if im just lucky or if they started to include one now.

Flywheel Conversion Kit - Valeo
Clutch engages very smoothly, car is a pleasure to drive again. The chatter is real though and does bother me sometimes.

SMF Conversion kit
Clutch went out, and wanted to get rid of the DMF. Everything was provided for installation, and fit perfect. Clutch pedal feels great, and similar to stock. Shifts feel more precise and no longer unpredictable. There is clutch chatter after hard driving (only noticeable at idle), and if you have music on or even an aftermarket exhaust you won't hear it. Car seemed to rev more freely with the SMF. Would buy again!

Noisy
Overall I was satisfied with the performance, a more aggressive feeling clutch that doesn't have a flywheel that is prone to failure. My only disappointment with this kit was the clutch chatter, It's faint to hear but overtime it becomes the only thing you hear...

Flywheel conversion
This is a night and day switch. If you want on point shifts and a harder bite this is your way to go. Been having it for a couple months now and I don't regret it maybe in future might go with the lightweight flywheel. If your on a budget I would highly recommend this.

dual mass to single mass conversion
Excellent swap from the dual mass flywheel and self adjusting pressure plate to a traditional clutch with pressure plate. The throw out bearing was not garbage like most replacements and it included bolts with loctite. I was not happy about NO alignment tool or pilot bearing being included. I already had a bearing and winged it with no alignment tool. ALL clutches SHOULD come with one, this does NOT!

Disappointed
I guess I should have paid more attention to the picture and listing. While the kit is overall pretty good, it doesn't come with an alignment tool. How ridiculous is that. You can't put the thing together without one, all the other kits have one, but for some strange reason, this one doesn't. So now I can order one and wait another week to finish the job and pay the extra shipping. Really disappointed.

Perfect upgrade from a dual mass!
So first things first, only one thing I’ve disliked about this kit, and that’s the throw out bearing. It looks very cheap and thin compared to a stock bearing. I recommend getting the Sachs bearing for 30$. Overall, this is a pretty easy installation, I recommend doing the rear main seal, pilot bearing, input shaft bearing, and pivot pin (get a steel one not brass) all when doing a clutch job. No special tools are needed, just a torque wrench obv. Shifts are a lot more precise like in any other manual car that doesn’t have a dual mass. The shifts are more predicable and a tad quicker without that hop at the end like a dual mass has when you try to go of the line a bit quicker than normal. Cons of a single mass kit: The clutch chatter is very present. Almost sounds like a tick or knock, but from the bell housing. It’s also very annoying when your at a stop light and The car next to you can definitely hear it if they have there windows down. It’s only really there at idle. Another con (for some) is that it’s a bit harsher of a shifting experience, Once you get used to the feel, you can make your car shift just as smoothly as a dual mass. Overall a good buy! Get rid of that shorty dual mass,

Questions & Answers

Ask a question
Question Posted by a customer
How many teeth are in this flywheel and what is the total diameter, as well what is the inner diameter of the flywheel and what is the diameter of the bolts for the flywheel to engine?
Answer (Posted by FCP Euro Products Team)
240mm clutch disc, 112 tooth ring gear, overall diameter of ~289mm, M12 bolts for flywheel to crankshaft, pilot bearing should be 32mm.
Question Posted by Guilherme
I’ve seen some reviews that says it does not come with the alignment tool even tho it is listed in the description is it included?
Answer (Posted by FCP Euro Products Team)
Unfortunately, Valeo has recently stopped including the clutch alignment tool. It is unsure if the mfg will send one with the clutch kit going forward but at the time, this will likely not include a clutch alignment tool.
Question Posted by a customer
I have a 1997 328i with 4 speed automatic, I’m swapping it to getrag 250 is this the right fit for me?
Answer (Posted by FCP Euro Products Team)
We do not recommend coupling a Getrag 250 with an M52B28. A ZF 310Z/320Z is a better choice. From there the correct flywheel conversion is p/n 52401210.
Question Posted by Jaxson
What do I torque the flywheel too
Answer (Posted by FCP Euro Products Team)
105Nm
Question Posted by Justin
Will this fit a 01 bmw m3 6 speed
Answer (Posted by FCP Euro Products Team)
No. This fits the vehicles listed in the fitment guide only.
Question Posted by James
Description says "This flywheel cannot be used with a standard self adjusting clutch kit". If I have a stock 1999 328i (assume dual mass flywheel) and want to use this kit, is there something I need to change or replace while doing the job?
Answer (Posted by FCP Euro Products Team)
This kit comes with everything needed to install. The note in the description is talking about when it comes time to service this kit. The flywheel, because it is a single mass and not a dual mass (damped) cannot use an OE self-adjusting rigid clutch kit. We have the service kit, made by Valeo for this conversion kit, noted as p/n 828484 which is the matching service kit for this flywheel conversion kit.
Question Posted by a customer
It says the alignment tool is included. Is that true?
Answer (Posted by FCP Euro Products Team)
Yes.
Question Posted by a customer
Will this fit a 2004 bmw 325xi 5 speed?
Answer (Posted by FCP Euro Products Team)
No. 9/2003+ E46 cars utilize a 22 tooth input shaft vs a course 10 tooth input shaft which is what this kit is intended for.
Question Posted by Max
what is the diameter od the clutch disk in this kit?
Answer (Posted by FCP Euro Products Team)
240mm.
Question Posted by a customer
do you know much the fly wheel weighs?
Answer (Posted by FCP Euro Products Team)
This flywheel is an OE weight coming in at roughly 25 pounds. This is not a lightweight/performance kit.
