Well, my once solid as a rock, super-responsive Boxster is an oversteer mess (or maybe it's understeer - it's just kinda all over the place).
Do you think I should replace the fronts with the HTRZ IIIs or just replace the whole set with Michelins, like the PSS tires?
I can't figure out if the bad steering is from the HTR ZIIIs or the the fact that I have two different brands, with one more worn out than the other. The steering was fine before I replaced the rears.

I replaced the rears on mine. It is handling better after a few hundred miles of run in. Also, when I checked the tire pressure one was about 32psi and the other was about 46psi.
