lwfw would also cause more chatter.
word of advise to OP... you only want to do this once, so do it properly. tho you already have posted a cost effective one... i would first think, on a serious note, what are the realistic future plans for the car? as far as power /torque is concerned. That way you choose a setup that would work for your future goal.
second, definitely upgrade the flywheel if you can... you're already in there... so why not get it done already. i'm a fan of chromoly flywheels for 90% of our clients. Its a common thing to say that you will be tracking and beating the car up all the time, but then how many times do you REALLY track / race the car? a little fun in the highway / streets isnt the same as drag racing or circuit racing at local tracks every weekend. So the lightweight stuff might sound tempting adn a better upgrade, but at what cost? more chatter, and less friendlier drive feel at daily driving speeds? sometimes a little less goes a long way in enjoying the car's feel.
third, DEFINITELY do the slave cylinder upgrade if you can. Zspeed has a great product and just like the flywheel situation... you're already in there, so why not???
last but not the least, if you are not boosting that car in the near future. Go with a Giken super single setup
