actually, ehdrian is right. I first thought the Ogura Super Single is hard to drive but surprisingly, its not. Its more easier to drive compare to puck clutches. Anyway, this is the whole story. At first, i was using the Exedy 4 puck clutch and one day i went through a flood, not very deep. Soon after that, my clutch started to slip. Went to the workshop and dismantle the clutch. The 4 puck clutch plate is fairly used and the pressure plate has a very small burn mark. Since the 4 puck is out, i decided to change to the Exedy stage 1 clutch (organic) due to the heavy traffic which i have to go through everyday. After a few months after i replaced the clutch, which is recently, it started to slip after all the traffic i went through. Brought it to another workshop for checkup and found the exedy stage 1 has more burn mark on the flywheel and pressure plate. The technician told me that the stage 1 could not take the abuse of all the clutch in and out operation during the traffic jam. So he recommended me the Ogura Super Single which could withstand the traffic better. So yeah, im now using the Ogura clutch. Man, this is a long story. Sorry about that guys..
