Which one? Going back and fourth.

OS Giken.

Elmo370z · 08-30-2017, 09:48 PM

That's what I'm leaning towards, any reasons why over the ATS?

Never heard anything bad about the OS. Never heard much about anything on the ATS. Good, bad, or in between. I'm leaning toward the OS when I need to replace mine.

The triple plate clutches are the same price as the os twin plate

The twin disc Grand Touring. Soft or hard cover. Haven't decided yet.

Me either. So excited I get to go to MaMotorsports next week to blow money and talk about my clutch set up for my turbo kit

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.

I have had the OS Giken twin plate Grand Touring with soft cover for a couple of years now. A very good and well engineered, premium piece of kit.

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

The soft cover gives less clamping force than the hard cover, but I have no issues with any slippage using the soft cover with twin plate with a supercharged 450WHP. With the soft cover it's not as hard to depress the clutch pedal as it would be with the hard cover, that's the reason I went with a soft cover. I had no issues with it on the track either.

The pedal effort of the OSG is no problem at all, its similar to a stock clutch. Its the resolution of control you get within the swing of the pedal that makes it difficult to drive. Fully engaged and fully released feels like its about 1/4" apart. I am sure its more, but thats how it feels. To push the clutch pedal enough to feel any hydraulic resistance at all, and you are pretty much disengaged at that point.

This is just my experience, and its possible that different slave cylinder arrangements could drive much differently (should their displacement and travel ratio be different than mine was).

Juan@Fontana · 09-01-2017, 11:38 AM

we have installed many of both, i can say 100% OSGiken is the better made unit. drives better, feels better & manufacturing quality looks better.

phunk · 09-01-2017, 08:35 PM

A multiplate clutch doesnt mean it has to be an on/off feeling clutch. Each one can have its own characteristics.

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.
