Hello Robert,

There has been several documented crankshaft failures due to removing the DMFW as you will no longer have the harmonic balancer effect that is build into the DMFW..

However you may want to explore installing a front pulley that has a balancer build into it, I believe that some of the GT3's came this way from the factory, this should help you to counteract the bad harmonic vibrations that cannot be cancelled with a low weight flywheel.

Please note that by any means I am no expert on this subject.. but have been reading about for more than two decades ever since I installed a LWFW on my 1.5 Fiat X1/9 and then into a 3.0 Alfa V6, but somehow I chicken out on the 987CS ...LOL

One thing for sure is that you Will Love the way how quick the engine will rev up (and down..) after installing a LWFW..

Good luck with your project
