I found through searching google that the sock 1.8L flywheel is a staggering 19.5lbs. And I wondered why it revved so slow. :lol: And I found through the same search that the Fidanza aluminum flywheel is pretty much 8lbs. That's quite a bit of loss on the rotating mass of the crankshaft. But what about the other flywheels? I see three others on AAS, and none listed on corksport, I figured they would have their own, or is it just not listed under their escort parts? And also, are there any other modifications needed or are lighter flywheels just a bolt on part?
