Seeing as how many of us are looking at increasing our HP substantially with the ATP upgrade as well as a few other options, what clutches are people planning on running?

Broken ones.

nobody is ready for 400Whp with rear axles breaking, and so many issues with rattles such outside the box I think you'd better wait awhile for that dream......

The axles are breaking due to rear differential mounts breaking. There is a company affiliated with this forum who is working on that remedy as we speak. As for the clutch, I hope Discount Power Parts (I think is who mentioned this) is still taking on this task. Otherwise we'll just have to wait.

Thats kinda what im getting at. Everyone seems ready to buy a turbo, and there seems to be plenty of aftermarket support for power upgrades, but there seems to be no support to beef up the drivetrain so that it can withstand it. I was hoping Exedy would step up and come out with a carbon setup, but im probably dreaming.

I know a guy who did some 4 puck and segmented kevlar disk work on my old car, added about 30% to the pressure plate along with it and they held very well... I will try to find him and ask about it... any one have any knowledge of PP force or disk diameter?

best combo would be a stock disk with a high pound pressure plate.

Maybe we can get these guys to help out with a clutch like this one.

http://www.roadraceengineering.com/evo/nonameclutch.htm

They also have a "NO NAME" ligthweight flywheel as well. Maybe someone in that area could get ahold of them and ask them about it. I would... but I live on the opposite side of the country from them.

I realize the Mazda 6i and the Mazdaspeed 6 come with different clutches. However, does anyone now if the Mazda 6i clutch would operate in the Mazdaspeed 6? Obviously a stock 6i clutch would be a downgrade from the stock Mazdaspeed clutch, but there are companies that make high-performance replacement clutches for the 6i. If they would fit, they could be a viable option. Anybody know for sure?

As a side note, when I had my clutch replaced my service guy said, the clutch factory clutch was a ford/motorcraft clutch. He believes it is the same clutch used in the Mustangs. However, he doesn't know for sure. I have my doubts, but it would kinda make sense given the parts sharing between the companies and the fact that the GT mustangs also have a large amount of factory torque. If it is true then there are all kinds of options. Has anybody researched the stock clutch in depth?

I don't think the clutch will be the weak point and fail – if an aftermarket clutch is installed, it would probably just exacerbate failure of other components - such as the rear end and axles - whereas if the clutch fails, that would be a relatively inexpensive part to replace instead of breaking other drivetrain components.

Well im sure for those that feel drag racing their AWD sedan and doing 5K RPM clutch drops that would be the case. But for those that want their car to be able to put the power to the ground consistantly without worrying about the clutch being able to couple the power, an upgraded clutch will not be any harsher on the rest of the drivetrain.

True.

I'm only 90 minutes from RRE - perhaps I'll give them a call tomorrow and see what they have to say.

I can't say yet, but rest assure they have a good reputation among us. That particular peice isn't due for release for a couple months, but they claim to be making a full set of replacment mounts. Everything from engine to diff.

I ran an ACT 2100 to [email protected] in my Talon, I don't think we need a crap load of clutch for a modest buildup.

As in DSM's I think we need to look at the clutch in the Speed6 as the "fuseable link" in the drivetrain, run too much and you'll break stuff continually, run a bit less than needed and you'll be fine and you'll wear out a friction disc early worst case.

The link that WRC2 provided for SR Motorsports lists different part numbers for the MS6 clutch and flywheel than the part numbers for the Mazda6i. This suggests to me that the aftermarket Mazda6i clutches probably won't work on the MS6. :(

Hopefully, I'm wrong about this, because some of the aftermarket options for the Mazda6i look great.
