I have no money. You're the one building a race, has a motor home, owns a ten story house. I'm over living under a cardboard box and eating can chicken noodle soup

I have owned both. I liked my twin carbon ATS/Carbonetics better than my twin OSG. When at typical operating temps, it drove like a stock clutch. When you heated it up, it got grabby like a racing clutch. Downside to carbon is that if you failed to warm it up before racing (high power application), it might slip under full power. So when it mattered, I would warm it up first. If I had the triple carbon rather than twin, it most likely would have held the power without having to heat it up first. It seemed like I was right on the edge of what the twin could do at normal operating temps.

My experience with a twin OSG in my own car, and a triple in a friends car. Great quality and longevity. But as for drive-ability on the street... Well you wont have to ever worry about hiding your keys... the average driver will not be able to make it out of the driveway with that clutch. It wasnt even tolerable (for street/daily use) before adding the adjustable fulcrum pedal from RJM. Even then with years of daily experience driving it, I would still stall it every few days. That is a racing clutch, and it drives like one.

Thank you. The answer I was looking for. Fuel rails whenever you get a batch :tiphat:

I will be going for OS giken GT single hard cover, it will be an option if you don't want to boost your car. I don't want to go through the on/off feel of twin plates.

What's the difference between the hard and soft cover?

I haven't noticed any particular "on/off" feel of the twin plate that you mention. It's obviously firmer to depress the clutch pedal, but other than that it feels like using a "normal" clutch to me.

As for the OSG appearing nicer quality than the ATS... Its been some years since I looked at my ATS and never held them side by side. But that clutch lasted me over 5 years before it started slipping, so I wouldnt worry too much about how pretty it looks inside the bell housing.

Im surprised to see people in this thread that are happy with the way the OSG drives. I guess to each their own. Everyone that drove my car hated it, and only a few of them were even really successful at it. Perhaps there is a different model than mine and my friends that drives nicer.
