Need a new clutch, which one to choose?

My 1984 Targa clutch looks like it needs to be replaced, pictures below.

The engine is stock, so should I go for a stock clutch? This one? https://www.pelicanparts.com/More_Info/91511691100.htm?pn=915-116-911-00-M38&bc=c&SVSVSI=0581

flywheel looks a bit beat ...

cant tell much else on the disk from there pics, there is new thickness, wear limit etc, depends how thick it is
I didn't replace mine on my engine build as there was lots left. based on current usage i calculated i will hit the wear limit in 42 years.

Yes, a Sachs clutch disc will be a good choice for OEM. In addition, at the very least you'll need a new release bearing, pilot bushing, pressure plate, and to get your flywheel resurfaced.

The bottom image is of the flywheel, so I imagine the surface your pressure plate (PP) is marred up as well. There's no transaxle fluid on your flywheel, so you know the o-ring in your transaxle is good, and that the rear engine oil seal is okay.

You might take a look at this YT video, where Kurt goes through a complete clutch job:

Stock sachs kit and a new flywheel. Good to go. Light pedal and no shudder.

Can I get my existing flywheel machined or is it really better to just get a new one.

If you're a pro and working on a customer's car, you put in a new flywheel. If you are a DIY, like me, you have the old one resurfaced, if it isn't deeply scored.

And if their grinder is true, it works, if not, it shudders. Ya pays yer money and ya takes yer chances. That's why I go new. Don't like to redo stuff.

Most people don't get a new flywheel during a clutch disc replacement because the shop will have them resurfaced somewhere. (probably call a Porsche shop and tell them you're a DIYer and would like to know where they get their flywheels resurfaced). However, a new pressure plate is typically purchased at the time of a clutch disc replacement.

When I did my clutch I resurfaced the flywheel and it came out nicely, no shudder after assembly. I think JWW is right though, need to make sure it's a good shop with the right equipment--I would hop no shop would go around resurfacing flywheels without knowing what they're doing, but you never know.

A new flywheel is $400. Not sure what it would cost to resurface, but let's say $100. In my opinion, $300 savings is not worth the gamble that may force another engine removal.

using a new flywheel is the best option, imho.
shop around - price fluctuation extraordinaire.

Thanks for all the input.

I ended up getting it resurfaced at a reputable local shop and then getting flywheel and new pressure plate balanced together at another local shop.

I'm just wrapping up getting my car back together. I also started out with just replacing the clutch. Tranny rebuild, new alternator housing, new fuel lines, new stainless exhaust pipes and muffler, powder coat a lot of stuff and more new stuff.

For the flywheel, I bought new unused Fidanza light weight off ebay for $200. I've got no real interest in a lightweight flywheel versus standard but the price was right so I thought I'd give it a try. If I don't like it, I'll go back to stock.
