Yep!
The marks on that diaphragm are from the fixture that holds the unit together while we torque the internal pieces to spec. These do require a radiused face bearing and that is included with the package, we offer a piece that allows you to utilize the stock slave/bearing assembly.
The unit requires considerably less travel than that to release, but yes, we're very aware of what you pointed out.

I could get you a clip of the 28lb revving in a couple days because my exhaust consists of only LT's and I don't want to **** off the neighbors three blocks away. I have the parts to finish it, I just need a miter saw and a mig welder. :-p
Steve told me that the 18lb revs WAY too fast for the street. He said it should only be used for a dedicated autox or road race car.

Why would fast revving be a problem on the street? Because you'd need too much throttle and slipping for smoothe take off? Or because it would stall on decel? Or do you mean that it would not have enough thermal mass and would overheat at 18#?

I was told the twin would overheat and be nearly undriveable with the 18lb. It's just not enough MOI for a street car, and it would probably need a retune to even idle correctly.
That said, Steve also told me MOI on the twin with a 28lb is still going to be lower than the 11" Ceramic race with an 18lb flywheel.
IDK if this is the old style twin, or this current version. But here's a Monster twin revving:

So I will be getting the exhaust done this weekend finally. I had to rebuild my 7/8" Wilwood master as it would not bleed. I had a 3/4" on there and it felt REALLY nice but I wasn't getting enough travel out of it. I could not go into any gear. With the 7/8" I have no issues getting into gear but that pedal will make a man out of you.....
If I decide after break-in that the engagement point is far enough from the floor I'll look into getting their 13/16" MC. As of right now the pedal is just too hard but if it's what it takes, I'll learn to love it. By the way, the first 10 feet after the clutch swap, it clutch was smooth right out of the box. Level one btw.
FYI this is a RX-7 swap so it's not your normal GM/Tick setup.

Thanks for all the compliments guys!
We do not recommend using the lightweight flywheel for the street for one main reason; you're going to prematurely wear the frictions from excessively slipping the clutch due to the lack of rotating mass. It's not the overall weight that is the concern, it's where that weight is. The MOI of our lightweight twin is ridiculous when compared to a stock unit. It works very, very well in an application where rev match shifting, etc. is done regularly.
Let me know if you guys have any other questions!
