Clutch/Flywheel Recommendations

[ChipG]

Hey all, I need to replace the clutch (and probably flywheel) on my car. 2020 GT350, stock powertrain. I track it several weekends a year but it's also a daily driver. On track I'm using GY SC3 tires, not slicks. What are your recommendations for a setup that will hold up to track use but still be street friendly?

My personal preference is to stay away from multiple disc clutches, it's just more stuff to go wrong. In the S197 world, the Exedy Hyper single is the complete, total favorite, no brainer clutch, For my 07 Gt500, I had to go to a single disc Spec (which is sort of a hyper single knock off) because of availability. Keep in mind you may have to do some type of relearn to make the ECM happy.
Now might be a great time to consider a lighter flywheel if you do any autocrossing.

Don’t go aftermarket on the FPC. Stay oem. Stock flywheel is dual mass to compensate for vibrations.

All the clutches I'm seeing listed come with a flywheel, is it possible to get something without buying a flywheel as well?

Stock replacement part is FR3Z-7B546-D and comes with just the clutches and pressure plate. It would still be a good idea to resurface the original flywheel if you plan to re-use it.

Not that I am aware of. I also just don't see the value. The big performance gain comes from replacing the flywheel with a much lighter AL version. The stock clutch pack is very capable at stock power levels.

Service manual calls for replacing both the clutch pack and flywheel. I agree given the dual mass design of the stock flywheel. If it fails, it'll vibrate your engine to death. I've seen a few cracked blocks from that and I know the FRPP school cars had a few issues with that same problem.

Sorry, my question wasn't clear. Stock clutch replacement is easy enough. I'm asking whether aftermarket clutch automatically requires aftermarket flywheel, or whether there are aftermarket clutches available that can be ordered separately and work with the OEM flywheel (and clutch slave cylinder).

Thanks. I was just at the dealer and looked at everything. The initial problem was the clutch slave cylinder. They were going to replace the clutch as well under warranty but it showed too many signs of high heat (bluing on the pressure plate fingers etc.) and they said Ford wouldn't sign off on a warranty replacement. It's been soaked with brake fluid so I figured better to replace it. Flywheel looks good though and checks to spec. Service manual checks all lead to "do not replace." No fluid intrusion, no cracks, minimal hot spots. So, sounds like best plan is just put the OEM clutch replacement in and call it a day.

New clutch = new flywheel, it's just the cost of the part, you are already there and especially being its a dual mass.

@ChipG How much is the OEM clutch?

They quoted me about $680 for the clutch and $1600 for the flywheel.

that's some real good advice

Why don't you drop a line to Kohr Motosports and see what Dean recpmends, he'd be the go to guy on this I think

I have the FR3Z-7B546-D & Fr3Z-6477-C (flywheel) NOS (was bolted to crankshaft but never used). You can PM me if you decide to stay stock.
