RS4 Flywheel machining. The original flywheel weights 12 kg.
I bought this used parts from Ebay and the surfaces needed refreshing, and in the same time I decided to remove some weight from the FW.
I took a tube that fits inside in the back of the FW and then cutted a flange where the FW is attatched.
Then I welded the flange to the tube and machined it straight.
Here the flywheel is opened half, and the spring plate is still inside. The front disk is 3 cm thick and it weights 4 kg. The back is also 4 kg, as is the dampener system.
I wanted to remove the dual mass system, and machined the spring plate open and removed all duall mass system parts. Now the flywheel parts weigths 8kg, but I am considering to remove the whole back plate and move the toothed ring and the pulse ring to the front disk. I'm just not sure if it is strong enough stand the starting forces.
