    I went with the 625's because once you put them in that's it. With the 425's you have to go back in and re-torque them big pain the a$$. For the difference of about $500 IMO it's worth it.

    You can torque the 625s to a higher value without an issue of them stretching or breaking. Under most applications 425's work just fine.
