Suggest a Clutch/Flywheel. Centerforce DF. or Spec STG3

well. my cars pretty modified. and its had a warped flywheel for a while. the chattering is getting pretty annoying. it has a zoom clutch.. so i was told from the previous owner that mentioned the flywheel.

so anyways i figure i might as well get a fresh, better clutch when i fix the flywheel. and throwout bearing. and adjustable clutch quadrant cable. anything else im missing that i should get?

anyways.
im either going to buy a Centerforce Dual Friction Clutch w/ one of thier steel flywheels.

or a Spec Stage 3 clutch. since it lists it as their 'ULTIMATE STREET/STRIP CLUTCH!' and one of their steel flywheels.

any feedback on the clutches would be great. this will be a daily driver. so it must be streetable.

here is my combo so far. with more power and parts soon to come. probably nitrous too.

edit:
also, is that $70~80 'lightweight' option for spec clutches worth it? really drop off that much weight?
