New Clutch installed on my F13 M6 *pic heavy*

BIMMERPOST
     Featured on BIMMERPOST.com
Hi Guys,

After multiple track days and pushing over 680hp/680tq my clutch was TOAST! The clutch started to clunk going into reverse and 1st. The clutch couldn't hold the power I was making and started to slip in every single gear. Even after changing the tune back to stock the clutch was still slipping.

I found South Side Performance, owned by Kris, who sold upgraded clutch packages. Andym3100k posted saying he upgraded his clutch too, so I made the call and talked to Kris for an hour trying to decide what to do. We ended up upgrading everything he had for the transmission. We changed the output basket to billet baskets, changed out the bearings in the pump to bronze bearings, changed out the old filter to a steel filter, and upgraded the clutch that can hold more than 900 ft/lbs of torque!

After 1.5 days of taking out the transmission and putting it back in, the car runs as it should. No more clunking and smooth as butter going into gears. I'm currently breaking in the clutch before tracking it at Auto Club in Fontana for Bimmerfest.

I want to thank Kris @ SSP for helping me through out this whole process. He answered my calls and gave me A LOT of support. Awesome company and a great person to deal with!

If anyone has questions feel free to contact me anytime.


*UPDATE* I broke in the clutch 500 miles Wednesday night. I was able to get on it and WOW the power is holding and it's SOLID! I'm excited to go to the track this saturday! Will post updates as the days go by.

Very cool, thanks for the pics! Have never actually bothered to look at the DCT clutch packs before, very interesting to see this. Heard DCT-type clutches once described as "motorcycle-like" and that's exactly as it seems...just bigger.

+1 - What he said.

I knew the drivetrain would have to be one of the weak links when upgrading performance on the M's. They already have so much power it's amazing to me that they hold up at all, let alone once you guys doing mods get after the motors. Being an electronic guy and barely understanding engines, I would not know a good transmission and a good clutch setup if it hit me over the head, but I know it is essential to a good running, high power output car. I've heard and read rumors of people working on stuff like this. It is great to finally see something from someone who has actually done it.

Did Kris give you any idea how much power he thought this setup could handle? I am thinking maybe some of his other customers had given him some feedback.

What have you done to get that kind of power out of yours?

So many people do all this great stuff that works really well but it takes some time in service to know how well it really is working. So many of these things sneak up on you - no idea what is going on until something bad happens. Of course, other times there isn't anything to worry about. A lot of it can be your driving style too. From my experience (mostly what some real pros told me when I used to do this stuff) avoid doing anything that causes wheel chatter or wheel hop, or at least do not let the car do very much of that. If it happens, fix what is causing it or do things to minimize that. The drivetrain will last a lot longer.

Thanks so very much for posting this, plus all the pictures . That really helps with understanding these things too. And please keep us updated as you run this. Obviously the stock setup was slipping. I'm wondering if you will see any measurable improvement now that it isn't doing that anymore.

Kris told me it can handle 900+ tq crank. I'm breaking in the clutch...I have about 200 miles to go. I track the car on a road course at least once a month so I do abuse the crap out of it. I'm heading to the track this saturday and will let you know how it goes

Did you ever use the launch control as well before replacing the clutch ?
Also how many miles did you get out of the factory clutch ?
Great write up and pictures.

I used it maybe 5x since I've owned the car. I got 20k out of the clutch...well I bought the car with 13k miles and put 7k hard miles on it and it went out.

I still have not tried to use LC on mine. After seeing some posts here about it I looked up the procedure once and thought about trying it. I didn't t the time because i wanted to put some more miles on it - nothing for longevity like breaking it in right and making sure everything has been properly seated. Right now I'd have to check again to be sure how to do it. I think I remember but I've had so much going on and it's been long enough that I'm not absolutely sure how to do it - boy, getting old is sure the pits. When I was young - break in service at 1200 miles, first LC would have happened before 1201. And probably 4 more times before 1202.

To be honest, I kind of wonder what the point is. I've read guys who drag race say that they have trouble getting their tires to hook up, and that's even with larger than stock race tires on the car. I think one guy who is particularly fast in the quarter said he had better launches by feathering the throttle a bit and had stopped using LC. I guess what has kept me was my tires already spin without WOT just trying to get out in traffic. I'd hate to think what they would do if I actually was trying to go really fast. I guess I'll have to try it out to see what it's all about and what I have been missing.

Whoa! Just 5 times. Those 7k must have been really hard miles. I don't know what the warranty policy is with second owners but I would have thought a car with only 20k on it would still be under warranty. Did you just want to have a beefier clutch than stock?

Personally I think you ought to get some kind of reward for this post. Definitely one of the best I've read. And I loved all the photos too.
Great job! And thank you again! I can't wait to hear how this works out.

MichaelBlake I do have warranty, but I want to beef up the clutch so I don't have this issue.

The clutch performed FLAWLESS! No over heating or slippage. I did 4 session 25mins each and was ALWAYS on it. I'm very impressed!

Have you tried launch control since installing this DCT upgrade? Is there any difference? If this setup will handle 900 ft lbs LC ought to be no sweat. Guess I am mostly curious if the tires spin more now than they did with the stock setup, although I guess it might be hard to tell exactly when that clutch started slipping.

Great to hear such a good report. Would you please PM me with contact info for SSP or who I can get these pieces from? One additional request for the PM - I'm also curious whose aero pieces you are using and how much you think they help. In addition to your subjective feel for it I would be particularly interested in any quantitative info (logging data if you have tried monitoring this). It looks like a Vorsteiner front lip and rear spoiler but when zoomed far enough to see them either my monitor is kind of distorting the images or they are just pixelating too much. I wanted to be sure. I am looking to get some right now but want ones that really work well and are not primarily just for cosmetics.

Those are some great shots of your car. Impressive photography of a great looking car! Please forgive me for removing the pics. I just did not want to clutter the thread with more to download than needed and they are right above this post.

All you guys going out having all this fun on the road and straight line tracks is giving me some bad ideas. I know it's what BMWs are built for and especially the M's , but I'm too old for this stuff. That said, it sure is great to have all this incredible feedback when I'm looking for things I want to do to mine and do them right the first time. Thanks everyone.

For SSP parts you can contact me directly and I can get the parts for you.

For the aero stuff I don't think it really helps. More for cosmetic looks. I need to talk to APR for actual aero pieces.
