I change out my original clutch after 400,000 miles and installed an ACT 4 puck ceramic disc with a heavy duty p/plate. After one year of running the car, I starting having shifting issues. Initially I thought the slave cylinder was giving up and after replacing it and still having the same issues, I thought the p/plate gave out, so I went ahead and bought another ACT 4 puck ceramic disc and a heavy duty p/plate.But when I dropped the gearbox, I realized that it wasn't the disc or the p/plate, but the flywheel. It was worn down a lot and the disc wasn't barely grabbing onto it. And because I couldn't afford any downtime, I installed the 2nd new ACT clutch kit with the worn flywheel. The clutch bites but not at fast as it should at high rpms. So I can't shift fast when I'm running out my rpm. I need to replace the flywheel and install a carbon/kevlar disc and heavy duty p/plate. Oh, and my water pump pulley is so badly worn from the the back of the belt running on it, that it actually has a groove in the pulley and is cutting that new belt that I recently installed. So I already have the new pulley to swap out.

Parts that are still working properly:
1. All Sensors (Oxygen, Crank, Cam, Knock, Coolant Temp, Oil Press)
2. A/C Compressor
3. Electric Power Steering
4. Fuel Pump & Injectors
5. Ignition Coils
6. Radiator
7. Brake Booster, Master & Slave Cylinder, Rotors and Drums
8. Throttle Body
9. Engine
10. Manual Transmission
