I was getting loads of clutch slippage on my stock S15 clutch and it sure needed a change. So I started to look for a new one to replace it.

 

So many choices out there - stock, Exeddy, Project-Mu, Ogura, etc.

 

I came across a readily available Ogura Twin Plate Clutch. Many people told me that the twin plate would be a total hell to drive with and that a single plate was all that I needed. Well, we all know how hard racing clutches can be, even being very heavy to drive with.

 

Against all my friends and other mechanics' advices, I went ahead with an Ogura Twin Plate Racing Clutch. Here are some pictures of what it looks like.

Responsiveness

 

The response time to the engagement is almost not noticeable as compared to standard clutches. Even when I caught in a severe jam, heat was not a problem as the plates had grooves designed to channel loads of heat away from the clutch disc.

 

Performance

 

It starts off very smoothly at 2,000rpm and is a breeze when it comes to changing gears.

 

On Sunday, I tried it out for the first time at Geylang Patah's drift track. Going into the first left hand corner, I was going in at around 70kmh on 3rd gear at approximately 3,900rpm.

 

I clutched in, held the rev at around 5,500rpm and dumped the clutch while twitching the car to the left to initiate heavy over-steer. On the instant of the clutch dump, the tail of the car began to swing out beautifully with sheer precision.

 

In the past, I was not very sure on how the stock clutch would do the same job and give me the same feedback that I needed in a drift.

 

Conclusion

 

I'm totally happy with my Ogura Twin Plate. It's an easy to drive with kind of clutch while still providing the bite that is required. The multiple plates allow for a very smooth progressive engagement of the clutch as compared to single plates, which in turn is less likely to damage the drive-train with sudden jolts. Clutch plate replacement is also very affordable, plus the twin plates last longer than a single plate.

The response for a launch is very good, it gets my rear wheels spinning to initiate a 1st gear drift like a dream.

 

It cost around $3k for this model with labour in. I got it from Imperial Concepts

Not at all. Contrary to belief, the twin plate is even easier to drive with than the single plate clutch.

 

When I clutch in, the pressure feels just like stock, nothing heavy like those I'm tried out on my friends' EVO and WRX who changed to other single plate clutches.

In a jam, you can do a half clutch just before the biting point. The car won't move yet at this point, so you'd have to give it a bit of gas to make it roll forward.

 

I just got back from JB on Sunday nite after drift practice and I went through a one hour jam with no problems at all, not even a sore left leg.

Typically, clutches last one round of plate change.

 

So whenever you change a whole new clutch, it will last for about 2 years (that's the avg life span of an Ogura Twin Plate). After 2 years, you just change the twin plates at approx $450 per plate.

 

Then after another 2 years, you'd change the entire clutch itself.

I know. But they cater to a very different market, and I don't mean the rich and famous kind of market.

 

I have friends in other workshops who comment on how Iimperial even remains profitable given that their prices are the cheapest around, but I have my comfort level when dealing with them. I also used to think they were super expensive until I found out that I could fully trust my car to them.

so if my maths is not wrong,u have to spent ard $3900 for the next 4 years on the clutch....sweatdrop.gif
