It's never wise to buy a product for a Japanese car developed in bfe America aka not California. They have no idea what they are doing.

Why is that ?

[datboibrad]

some argue that all metal crank pulleys will increase any wobble in the rotating assymbly due to the fact it has no harmonic properties to absorb the movements and "balance" the crank/rotating assembly. however it offers a lighter weight product which allows the rotating assembly to rotate easier.

in reality the weight difference is marginal and isn't worth the long term affects of a solid pulley. i would definitely get the super dampener or just hold out till i could find a stock one

If you are going to run an aftermarket crank pulley, the rotating assembly should be balanced. Even with the ATI we run on our car, we still had the whole mass balanced.
