kaiten makes a nice all steel flywheel, and is extremely light. with only 80k on your car i don't think your clutch is going bad unless you ride it.

does the clutch slip at all? like when you put the the car in 5th and hit the gas and the rpm go up (really fast) and the car doesn't gain speed?

i would go with an exedy clutch or act.

 

Kaiten piece is 8.8lbs. ACT's prolite is 8.4. Both are around the same price, but not sure about quality.
