I'm ready to pull the trigger on a new clutch setup and was wondering if what I had choosen was a good idea. Spec 2+ SF463H kit, SF46S steel flywheel. Price is $411 and $259 respectively. With regards to the steel flywheel, some say aluminum is the way to go, some say steel. I'm n/a with stock drive shaft, but I plan to go to aluminum drive shaft and a roots blower sometime in the future. Please give me your opinions on these choices.
