I just got a 997tt a couple months ago and already got straight pipes and tune. But when I drive in 5th gear and give it the beans my clutch slips. WTF? I'm coming from M3s and it takes more than an exhaust and a tune to make the clutch slip. What would be a good clutch upgrade? Not looking to spend an arm and leg but something reasonable.

 

Hi J and congrats on the car! There are a few threads on this but it depends on all of your goals. I have the Sachs Sport that everyone loves in stock and ready to go. ERP would be the next step usually. Give me a call if you like and i can help you sort through it.

 

My goal is basically not to have clutch slip with mods I have already, doubt I'll do more mods I could be wrong lol. Not looking to break the bank. Shoot me your number .

 

The Sachs setup is the way to go if looking for a setup that will hold anything the stock turbo can throw at it.

 

What's the Sachs setup? What does it come with?

 

It is the Sachs motorsports pressure plate with part number that ends with 764 along with a variety of different friction discs...which depend on whether or not you keep the stock dual mass flywheel. I used the sachs friction disc instead of an OEM Porsche one. I don't think there is a huge difference in them personally. The engagement point is a bit more abrupt, but clutch firmness is unchanged. Took me a 30 minute drive to get used to the difference and not notice it anymore. It is the most "stock-like" clutch swap I've ever had in a car. Very happy.

 

Can I keep my stock flywheel?

 

yes you can keep your stock DMFW. I have the sachs 2.5 as well and it holds power pretty well.

 

+1 and there are 750/800 hp cars running it with great results. The flywheels generally are fine.

Yep. Mine looked pristine and I was having a decent amount of slippage. Don't waste the money on a new flywheel unless yours is torched.

 

You may not be aware but aside from driveability/launchability tradeoffs typical with light weight fw's, the 911 has a noise from them. I find the "can of bolts" sounds at idle in neutral that arist from a lwfw to be really really annoying. Makes the car sound like a hoopty imho, though some guys say they like it.

 

This is a great read on the "stage 2.5" clutch options:
