Here's a good list of things to change if you want a good refresh:

Very informative thread thank you for linking.

. As a side note, during a clutch replacement are there any other things I should consider doing "while I'm in there"?

I'd give "blue flywheel of death" a quick google before purchasing that.

Welp a quick google search found enough for me, so scratch that. I'll be going with an OEM replacement. Reviews on lightweight flywheels and SMG cars seem to be hit or miss, and for the labor I'm paying I can't afford the chance of a miss.

I had to stop before I went down a rabit hole. A very interesting find. You can get a UUC clutch kit 20% off though 🙃

Clutch is giving out and considering the possibility of a lightweight flywheel. This product seemed the most promising, anyone use it before?

In general are there any recommendations/pros/cons for a lightweight flywheel on an SMG car?

My JB Lightweight flywheel barely chatters. It doesn't chatter at idle at all. The SMG doesn't like it very much and I've had to relearn driving it. The weight does affect the software but it's not end all be all. The experience just isn't always pleasant. Sometimes I'll turn my car on and it'll slam the clutch instead of easing it and I have to pull the key out the N disappears. Downshifts above 4500 rpm are wonky. It searches and has a hard time finding the right spot. The automatic downshifting is twice as bad as it already was so anytime it drop to around 1400 rpm, I just pop it in neutral so my clutch isn't sporadically engaging and disengaging for a second.
All the SMG needs is a retune but no one actually does it. It's annoying because the CSL software is awesome. With a lightweight flywheel, it could be even faster. The market to pay for R&D just isn't there. You also have to tune the DME along with it to avoid misfires.

Well, that sounds super annoying...I wouldn't be ok w/that at all!

Yeah, that sounds just awful. I couldn't/wouldn't deal with a car like that. If you really want a fast-shifting "auto" trans you should look into a DCT swap. Otherwise, CSL software and the stock flywheel is your best bet.

manual swap and you can keep your lightweight flywheel

Inline engines have alot of torsional vibrations and the flywheel is a main dampener in those forces. Since I'm going to really beat on my car, I'd rather kill some of those frequencies. I do have most of the parts for the swap. I basically need a bell housing and a gear position sensor. It's just finding the time. There's ALOT my car is about to undergo so I need to manage my mods wisely like a diff rebuild. That one is not by choice but ole' Liquimoly chose for me.

I don't remember, if you do some digging you'll find them. I'm not mad I added a lightweight flywheel but the shift speeds have gone down. I'm just going to switch to a solid steel flywheel around stock weight. I've driven mine for 6k miles now and I'm ready for the SMG I used to love or a manual swap.

Do you know who this "alleged" person is?

I have a private msg for you.

Someone allegedly tuned the SMG so it should be possible to improve it.
