According to that link, I'm going to be 5.5% larger than the current setup. So if I understand correctly, if my car displays 100km/h, then my actual speed will be 105.5?

And this won't cause any issues with ABS/VDC/auto tranny, right?

I was close to buying the PSS as a tire upgrade, but just couldn't overlook the fact that four Potenza S04s were $800 compared to the $1200 that Tire Rack wanted for the PSS. I can't really judge grip on the S04s yet, bug they are definitely quieter than OEM.

You have to keep the front and rear tire heights pretty close to the same diameter for not to get any problems with the nanny controls.
