I've also wondered about the advantages/disadvantages of going to an aluminum flywheel vs steel.

Either way, good luck and I look forward to reading about the results.
From what I read the aluminum spins up quicker but also decelerates quicker and it will lead to me having to wind the car up from a stop to take off
I did the aluminum flywheel on my E36 and E46. From my personal experience I'm not sure I'd do it again with a daily driver. Due to the weight reduction it doesn't always maintain rpm at an idle. Less weight to keep the engine spinning so at times it dips in rpm then has to catch up which causes the rpms to bounce up n down a bit. Then there's the extra attention needed when taking off. No more easy take offs with little effort. IMHO they're probably best suited for track cars.
