Is there really a point to getting the fronts if it's only .5 mm thicker?

You didn't cut and paste the most important part of that post--the top part that said:

Stiffness increases to the 4th degree with a small increase in bar diameter. I could tell that the car plowed (i.e., understeered) even more when only the front sway bar was installed. Most factory cars are designed with some inherent understeer for safety, so I presume that H&R was attempting to balance the car with the selection of their bar diameters.
