Southbend SBCNIS-3 Billet Steel Flywheel
 

07 G35s Sedan 6MT
Hey all, I've been doing a lot of research of clutches and flywheels. I was recently educated on the light weight steel flywheel vs the aluminum, and was told that south bend is a good brand. My questions are, Is anyone familiar with the Southbend brand? and is the steel really and upgrade from the aluminum? Thank you all for your time and help in advance.
