Totally with Todd and Jake here.
We want the balance issues, harmonics and shock loading to be absorbed by the flywheel and not the crankshaft. The dual mass flywheel serves this purpose well. If we eliminate the DMFW we need something else to take up these issues to preserve reliability. Top Porsche race teams use LWFW but always build and balance the motor from the ground up taking these issues into consideration. You would never see Penske or Farnbacher bolt on an aftermarket LWFW without a complete motor balance and harmonic dampeners in place.
One of our regular track hounds "Insite" from Atlanta recently tossed his motor. He put a lot of track miles on that 2.5 but it failed shortly after the LWFW install. I wonder now if the two are related. Something to consider.
