BTW, I notice you own a GT. All of the problems reported were on GT-S models, if I'm not mistaken. So, statistically, you'd be 100% safe with the UR pulley...

my friend has a matrix, and he had the crank pulley, blew his engine. Dealer told him it was the crank pulley caused it. They said it rev so fast/high when he down shifted, not sure tho.
