Over the past few months I've decided that 700 hp+ is no longer a goal I want to attain. Instead I want to keep my car the way it is for as long as possible (2.3 with Fp red and all supporting mods), but I will be pushing the fp red once I go flex fuel. The clutch I have in the car right now is a Competition Clutch Twin with the race flywheel and I am looking for something that is more street driving friendly.

Right now the car is only make 415whp/ 405 tq @ 23 psi, but will be retuning on E85 when I get the AEM Infinity. What OS Giken clutch would be good for 500- 550 tq, but that you love driving in stop and go traffic. If I have to reduce the hp/tq to get a clutch that is closer to stock, than I will. I may launch the car 10-15 times a year, but I doubt I will visit the drag strip more than 1 time a year. I am fine if the clutch will last only 20k miles.

After going through the OS Giken reviews below, I still can't decide what clutch would fit all my needs.

I do not daily drive my EVO but I could comfortably do so with my Exedy Twin Disk Clutch and lightweight flywheel combination. I'm only putting down about 380 AWHP but the clutch was previously beat on pretty hard over several autocross seasons and has held up reasonably well.

My advice - don't over-analyze it too much; get the clutch that is within your current budget and one that can handle the median torque you plan on attaining. (if you over-build and get a bullet-proof clutch but the car stays at 400 whp for the next year - you won't be happy with the driveability)

It also depends on how much you will abuse the clutch and your style of driving. If you clutch-dump at peak torque every time during the 10-15 launches you plan to do every year, then the clutch you choose won't hold up very well.

 

Thank you for the insight. I will change my driving style to accommodate the clutch. My budget is up to 3k for a clutch that will meet my needs.

I spoke with a OS GIKEN rep and he said the following:

"The TR2C would be the more durable choice, as it is a full racing clutch. It will still be very easy to drive, yet be able to handle the harsh abuse on both the track and aggressive street driving.

The R2CD and R3C are more for drag racing. Gear changes while in lateral g’s may be a bit sticky. I would recommend you consider the TR2C instead. Pedal pressure between all the before mentioned clutches is the same"

So I am doing all the research I can to verify that the TR2C will meet my needs now and when I upgrade.

 

I'll +1 the Exedy HD Twin, best aftermarket clutch I've ever driven.

I DD'd my VIII with this clutch, now it's in my IX.

 

I had a single excedy and the darn clip came off, that is why I am staying away from Pull clutches.
