Question 20mm swaybar wearing bearing?

Does anybody think that by adding a 20mm sway bar to a 2.5RS the rear wheel bearing may have accelerated wear?

Obviously harsh driving and corning will wear the bearings quicker, but would the tighter rear end with the larger sway bar cause the bearings to load more under normal driving?

When ever you increase the performace potential of a vehicle, you open the door for accelerated wear and tear. The rear bearings on the 2.5 are notoriously bad to begin with. However I replaced both of mine and made sure they were properly greased upon installation. They have been fine ever since ~30,000 miles. I've got the STI/Prodrive-Bilstien/Eibach suspension with a 20mm rear sway bar. Its been working just fine for me.
