Kris mate, only the other suspension components will wear off quicker. You can always reduce tire pressure by 1-2 psi to conpensate for normal ride comfort.
It will put a big grin in your face at Wakefield, I tell ya!. So much more solid feel and more confidence in the front end makes a great deal of difference in taking high-speed turns with high accuracy. Makes the front really hang on in there.
I switched stocker to 750 greenies and that made a difference. Me mate used polyu and said thats even better!. Go for it!.
