Too good to be true?
 
I found an ebay listing for a full stage one exedy clutch kit and F1 Racing lightweight flywheel for $368 with free shipping (sans counterweight). No matter what I'm getting the exedy kit, but i stumbled upon the listing and for literally $28 more than the RacingBeat-supplied exedy kit, you get a 10.5 lb flywheel with it. I have heard of F1 racing before but not too much about how good their products are.

I know that the flywheel is not a neccessary part of a clutch job (resurface at most) but for the money I don't see why not do it, right? Besides, throttle response would be way better over the stock (right?)

Let me know your thoughts and comments about it. And don't reccomend me a super-high-performance 4 puck clutch that is super awesome because its for racing BS. I'm getting the stage one, the car is stock, S4 T2.

Thanks

I've HEARD that F1 is crap. I have no experience with it.

But...

I've HEARD that GodSpeed coilovers are crap too. I installed them on a friend's car... he loves them, and I thought they were decent - nothing special, but fine.

Thing is, I can't imagine someone seriously screwing up a flywheel of all things. And since it's made out of 6061-T6 Billet Aluminum (true billet aluminum) so the strength will be there. Friction material is supposed to be durable and grippy, so I don't think it should be too bad.

The counterweight is an additional $121, for those who might be interested in the kit as well.

"True billet aluminum" is a meaningless phrase..."billet" only describes (and not very well at that) the form of the aluminum, not the properties.

A "billet" is essentially a "chunk", you can have a billet of dog poop (which may not be suitable for a flywheel) just as well as a billet of alloy.

I just pulled off my f1 aluminum flywheel, 6-puck copper ceramic sprung clutch and pressure plate the other day.

The flywheel was fine, never had a problem with it.
The clutch disc seems to be pretty ok too, not as terrible as I had heard stories about.
The pressure plate is a waste of materials. Way way too light of a clamp load. Can barely feel the pedal. The whole setup would probably have been much better with a beefier pressure plate. Make sure it is in fact an exedy pressure plate as well (should be)

I can take some pics of the flywheel for you today if you want?

Also try and get your hands on some OEM or equivalent bearings (pilot, release). The ones f1 will likely send with the setup will be shiny paperweights

Thank you, that's what I was looking for. And if you could then yes please send pics. And the onlything supplied by F1 is the flywheel. So the whole clutch/PP/throw out and pilot bearings are from exedy, the flywheel and counterweight (purchased separately) are from F1.

@Clokker, I was just making the statement after doing a whole 5 minutes of research. I am by NO MEANS an expert in metals and machining or any of that. :blush:

Eh, I dont think Clokker was talking down to you about using the term "billet" as much as he was chastizing the company for using the word as a selling point (as a ton of them do).

shadowghost21 03-21-12 03:21 PM

I really liked the billet of dog poo thing, I was loling all the way to the break room I am sure my coworkers thought I was mad!

Great...Damn dog...now I got Flywheels all over my yard!

Just so, pedantic asshole that I am.

In general- and keep in mind that "billet" is not a technical term at all- a part is machined from billet (i.e., a solid chunk) as opposed to being cast to shape (possibly with finish machining).

"Billet" in no way describes the properties (or reputed benefits) of the metal alloy..."machined from billet aluminum" and "machined from T-6061 T-6*" could describe the same part or a very different animal altogether.


*T-6061 describes the alloy itself, T-6 describes the heat treating it's received.
Just so ya know.

you get what you pay for

REAmemiya_fan 03-22-12 09:34 AM

Thanks guys, I think I'll just pass up that deal. Seems too fishy for me.

rx7-kid 03-22-12 01:31 PM

I also got the flywheel everything works fine. I got the stock excedy clutch with the flywheel. Riding on almost a year now and everything is fine.

Agree.

I just put in an Exedy OEM replacement clutch on my N/A. It clamps fine, but it's a really light clutch pedal- Lighter than the stock clutch it replaced.

fidelity101 03-23-12 09:37 AM

I bought a fidanza aluminum flywheel for (turbo) my car and I was using a stock turbo clutch and I had to file the holes on the PP for the alignment pins...

Racing beat fit and worked the best, they just had weird hardware spacers in their get up.

REAmemiya_fan 03-23-12 10:05 AM

Well as plans are right now I'm buying an S5 GTU to use as a daily and stock E (IIRC) class auto-cross, so I doubt I will be allowed to use a lightened flywheel. My plans have changed a bit since the start of this thread. But all in all this can be used to discuss flywheels and their ups and downs form different manufactures.

Logicalbomb 03-23-12 08:02 PM

If you want a nice flywheel find one from an automatic tranny in the 13B they are cross compatible, lighter, and above all much more reliable. Everyone that has serious HP in my 7 group that bought and installed aftermarket "ultralight" flywheel got an ultra amount of no friction and a distinct burning smell. The auto flywheels go for dirt cheap too and handle much more horsepower up to 480 on our fastest 7.

Lol... Exsqueeze me? I don't remember it having a friction surface....

RotaryEvolution 03-23-12 10:20 PM

^ he obviously regurgitated some bullshit that one of his fellow racers spewed at him(blame the source not the messenger).

the auto's had no flywheel, they had a flex-plate to bolt to the torque converter for the automatic. the flex plate cannot be used in any manual transmission car. the autos DID have the rear counterweight that ALL lightweight flywheels require to be installed onto a rotary have.

so this ultra fabulous automatic part is... the rear counterweight. a chunk of weighted metal with a few holes drilled into it, that some manufacturers took advantage of to make lightweight modular counterparts of.

knowing is half the battle

And it seemed like the flex plates only job was the engine to starter interface...?

You're right he only used the counterweight :D that's why I do not touch transmissions. When I called and asked what he meant by that he started laughing and told me it was the counterweight coupled with a lightened flywheel, my bad. Not bad info, just badly regurgitated.
