Save your money, honda is smarter than some knock off company.

If they are so great then why does NHRA/NDRA/IHRA ect all REQUIRE THEM. You can not compete in any NHRA sport compact event in any class besides brackets with out a SFI Balancer. Funny no matter how fast or slow they require you to have a harmonic balancer/dampener on your motor, maybe they help the motor and NHRA is tired of cleanup.
Heres my pulley setup, I guess I should go get a shiny pulley.

Harmonics dont care about horsepower, I have seen little wimpy motors shakes themselves apart and big fast motors live forever. But what do I know? You can choose to put whatever pulley you want on the car, but until you have torn down motors and see the damage, or seen stock pulleys sheer apart becuase of out of balance motors then maybe you will understand.

Too many people by Egay clutches/flywheels/pulleys from companies who do not balance their parts.

Its your car and you can bolt what ever you want to, just dont blame the machine shop or the junkyard where you got your motor if it has bearing issues.
