New stuff. A Fidanza Aluminum 11 LB Flywheel and a South Bend DXD Stage 6 FE-X Clutch utilizing a modified 350Z pressure plate (SS-X) which delivers 2700lbs of clamp load with an unbelievable light pedal. :icon_bigsmurf:

Nice to see you finally got a new one. I know the old clutch was giving you issues late last summer.

The South Bend DXD stage 3 was a really good clutch. The problem was that my motor was making a lot more torque at low boost than what the clutch was rated for. :icon_bigsmurf:
