They did have 11 and 13 as options when I bought mine from TTR. I think I'm glad I didn't go for the 11.
Sonic was just dropped off at SPEC!

Initially they wanted to do an aluminum one, but after some analysis of how much the part would weigh, I think they may be thinking steel now. They may offer both, but I'd rather have a steel one in my Sonic.

Very excited...this WILL be the clutch/flywheel I go for!
Are these gonna be available through your website when available?

That is good to hear. I look forward to more updates on this. I have been wanting a steel single mass flywheel. I may have to give them one last chance.

What is the word on commuting/stop and go driving with this set up (I know you don't have it yet, what do you expect?). An ultralight AL flywheel is trick for racing but I doubt it is a great set-up for a car that is in lots of stop-and-go.
What weight are you looking to wnd up with? I've heard 35lb for the stock clutch and flywheel.

I don't mean to interrupt, as I want to hear Morgan's response to those questions. But I can add some feedback about the scenario.
Yes the stock flywheel and clutch have a combined weight of about 33lbs. I have an aftermarket 13lbs aluminum flywheel and Stage 4 sprung 6-puck clutch for the Sonic. I've driven it over 12k miles.
I emphasis the Sonic because my experience is more relative than what someone has experienced with say a Honda. I bring that up because on another group, someone was slamming 6-puck clutches, saying they were "awful" for daily driving. But there was no clue as to what vehicle he was talking about.
With that out of the way........ My set-up is surprisingly not bad for the street. It's touchy in the grab zone. And that is a good thing performance wise. I loooove it. The only time it's a bother is in long stop-go's in freeway traffic. But it's bearable. There is a noisiness issue, but a slightly heavier fly, like 15lbs should help.
Oh and if there is fear that it requires more leg muscle to push the clutch in, I will dispel that. It feels comparable to stock.

I was hoping the CM Clucth Kit was streetable so its nice to hear some feedback about that.SPEC has built two flywheels to test. One is aluminum and incredibly light weight(9-10lbs), and a steel one(15-16lbs). The steel one is what will end up staying in the car along with a Kevlar sprung disc. I would have gotten it back last week, but new flywheels bolts had to ordered since the stock ones are torque to yield, and should only be used once.

Sweeet, I have the stage 4 clutch. I didn't know it didn't need break in.

Hells yeah, I was hoping to see a light steel one.:banana:
I can't wait to see pics, hear review. I would consider opting out to the steel 15 in the next couple trans swaps.
I imagine it can accommodate most sprung clutches right? The stock dual-mass fly cannot, and only allows for GMs narrow POS clutch that is hardly good enough to be a lazy susan, IMO.
Also, mind sharing the p/n on those crank/fly bolts? If there is a lead time, it seems to wise to just be proactive and buy some now.
They ordered them, so I'll get the P# from SPEC and post it as soon as I know.
