The stock DMFW is expensive and heavy but does a very good job at dampening drive train vibrations.

A light weight flywheel (LWFW, such as the Aasco) won't dampen the vibrations quite as well and you may have some drivetran/gear rattle (slight but noticable) at idle. But the engine will rev up a bit quicker too. There are also some people who have said that the LWFW may not dampen engine vibrations which can result in engine failure (just do a search). I am not too sure about that but I want to pass on whatever I've heard, plus or minus.

I've had a LWFW for 18,000 miles and have a bit of gear rattle at idle but its nothing that I even notice. I like the quicker revs and it was much cheaper than the stock DMFW replacement that might wear out again in 50K miles.

Best of luck in whatever you choose.
