Took me a while to get an understanding of how all this works, or maybe I am still wrong. I have stock 2005 lgt, Double Mass, Flywheel... shitty. So the solutions are 2007+ lgt, 2006+ wrx Single Mass Flywheel... better. Now i'm not sure where the Lightweight Flywheels fit in, I assume they are single mass as well.
I was interested in buying the Exedy FF502 Lightweight Racing Flywheel, 12.7 lbs, with either Cluthmaster FX300 or Exedy Stage 2 Ceremetallic clutch.
I have a lightweight pulley as well, and am aiming for 375hp. I have read somewhere that I may get problems and error codes with lightweight pulley and flywheel. Can these be tuned out or is it a physics problem? Anyone use this setup or the Exedy FF502?
