SPEC Stage 2 or MazdaSpeed clutch?

I'm about to purchase the Quaife differential and a clutch (and possible the MazdaSpeed lightweight flywheel). What I'm wondering is how the MazdaSpeed Sport Clutch for the 3 compares to the SPEC Stage 2 that I was originally planning to get. According to the Mazda parts department, the MazdaSpeed clutch can handle 30% more torque load. This doesn't seem like much for when I go to boost the car a year or two down the road, but maybe that's enough, and I don't know how much the SPEC Stage 2 is good for, either. The reason I'm considering the MazdaSpeed one is that it's $150 less through my Mazda dealer. Any thoughts?
 
wow, you have enough money to get a quaife lsd but you are worried about saving $150 on your clutch? haha

anyway, there has been a lot of negative talk lately about the spec clutch. People say it "chatters". I am not sure what that means exactly as I still have the stock clutch, but you will hear people steering you away from spec
 
saw some neg talk about the mazda speed one as well.... so not sure what to tell you
 
I will be going with the mazda speed clutch as I also heard pretty
bad comment about the Spec clutches over the last months
 
My spec holds up fine...
In my opinion go with whichever is cheaper, because chances are 2 years down the road when you boost you're going to need a new one again then probably depending on how hard you drive your car.
 
I can't see needing another clutch. In 20 years of driving (aggressively) I've never needed to replace a clutch, even with my 202 whp/194 lb-ft of torque supercharged 2001 Focus ZX3. It went 80,000 miles over two years with that supercharger, and never had any significant problems (of any kind, for that matter). I'm buying a heavy duty clutch now specifically to prepare for boosting later. I'm leaning toward the MazdaSpeed clutch. If my Focus was fine with a stock clutch, then I have to think I'll be fine with the MazdaSpeed one for my 3, even though it will make more power and torque. I don't tend to drive in a way that's hard on clutches.

I wouldn't even think about using the MS clutch on a boosted 3, especially with the power we make on low boost. MS products are mostly copies of the lowest model aftermarket parts. Meaning the MS clutch is mostlikely similar to a Spec stage 1.
I say if you really wanna drive the car you will need a better clutch.

I'll be installing the Spec stage3
 
I have to think that the MazdaSpeed clutch is the one that will be on the upcoming MazdaSpeed3, which will likely make the same horsepower and torque as the MazdaSpeed6 (at least based on the last thing I read).

that will likely be the clutch, but I dont think the ms3 will have as much power as the ms6

I seriously doubt that will be the clutch they use and agree it wont have as much power as the MS6. I doubt it will even break 200whp on the dyno.

I also know for a fact that the MS clutch is not good for 300wtq.
