Clutch advice needed.....

Ok, so after a year and a half of ownership and some good time at the track, it's time for me to replace the clutch. Anyway, I've done some research and talked to a couple of friends, and they all recommended the Sachs clutch kit. So what is your opinion on this? Any other possibilities? Specific things that I should know/expect from this model? BTW, the car is currently rated at ~452hp/410lb-ft.

-Brembo 355mm Discs

-ACS SS
-OZ Superleggera 9x19/10x19.

and more to come.....

How do you come to the conclusion that your car has 452hp? Modified in some way? Dyno results? We would like those same results.

Thanks,

heh

50hp from the ole IHE eh?


what kind of exauhst is this?
just a muffler/catback?


or headders, catalytic converters and everything?


oh, and to actually give you some input, I was doing some research and found that these guys: http://www.dialaclutch.com/
who distribute the stock M5 clutch can add a kevlar lining for increased durability/clamping force. very inexpensive too.

havent tried it yet tho!

Yes, the exhaust system is the complete package. Exhaust headers and everything. Thanks for the link, btw. It looks like an intersting thing. I'll check that out.


MEnthusiast : Photography is just a hobby. I wish that I could do it professinaly, though.

Reflex-

The clutch is one area that's universally seen as a weak point, yet there's not been a definitive solution that's proven successful. I did a lot of research on this about a year ago, and then ended up getting a new clutch under warranty, so my investigation stopped.

My own M5 has never 'hooked up' as good as it did when new; I have a hard time breaking traction these days. Once hooked up, however, I have no complaints about power on tap. It's just that I don't go looking for stoplight drag races any more.

If you do a search using "sachs + performance + clutch," here's what you'll find:
http://www.bmwm5.com/vbulletin/searc...der=descending

I know of one member (540is) that installed the Sachs Peformance kit on his supercharged 540i. We've not heard much since the install on its performance.

I did have one California speed shop discourage me from trying the Sachs kit, as they said it likely would require some machining of the dual-mass flywheel to make fit. Sachs is NOT the OE manufacturer of the E39 M5 clutch--that job belongs to LuK.

If I had to make some changes on my own dime, I likely would go with an uprated Sachs clutch (can't beat the price on dial-a-clutch) and some aftermarket lightened flywheel like Dinan or UUC. I believe that would give me the missing 'hook-up' back, along with a more positive clutch engagement.

Good luck, and let us know what you find out. BTW, once you find your best price on anything Sachs, I would give the guys at Adirondack Auto Brokers a call to see if they can beat it. They are a great resource for Sachs clutches and Mintex pads (also Sachs). www.germanautoparts.com
