Ok as I stated above, a few hours ago I installed the flywheel and clutch kit. And what can I say. I am speechless. This mod is a MUST if you have a supercharger. The car has totally transformed. You can feel the power of the car going to the road and of course it leaves you with a big smile. The acceleration is something else. Lightweight flywheel, upgraded clutch kit, supercharer kit and short shift kit is a must for a Lexus IS200. Now on the road the clutch is a bit more hard to press to change gears but i got used to it very fast. Also it is to drive in traffic. The car does not kick when i start from stop and also during reverse-parking. I can only say now that the clutch now engages from almust the start and not half way of its travel.
Here are pics during installation:
