a manifold, an exhaust and YES a flywheel (yippee!). I don't know what the flywheel will do to the top end or high speed/high r's but I know on my Dinan SC'd 328is it KICKS A$$ around town! I can whip ANY M3 up to the quarter mile, especially 0-60 and I can't imagine a lightweight flywheel in the M but am staying up at night thinking about it. Does anyone else go to sleep thinking about your car arriving??? Any thoughts on the downside of a LWF on our cars? I test drove an M3 last week and was disappointed in the wallop I got when pushing it at low speeds - so used to being thrown back in my seat w/my 328...

If you read the Tech Article on SMGII, you know how much time BMW and Getrag spent on refining the system and getting an accurate software model to get everything working in balance.

I know the balance of the system is upset with the LWF and in my present case, just causes vibrations (which I think are very pleasing) but when traveling FAST, the LWF seems to compromise the whole system slightly - losing that upper end "smoothness".
