automatic soooooooo no flywheel

does the pulley really make much differance tho? i mean sure all rotating mass cut down helps, but it seems like an insignificant amount

i "might" have found a vendor for carbon hatches and hoods but cant seem to verify if the 09 units were the same.....certainly the hatch would be a good weightloss..i doubt the hood would be much

It helps in the manuals cause it makes it rev quicker and be more responsive which makes quick downshifts a bit easier. Otherwise it won't really help.
