Stiff sidewalls would make her complaints about the twitchiness worse actually. Take Nina's car for a spin on the StarSpecs if you want to know how it is.
Obviously the Dunlops get high marks around here, and we just put a set of the new Contis on Carrie's STi, maybe she can chime in on how they are in good weather. Last year they got awesome reviews for winter traction, and I am still thinking about them for the FXT.
By the way, KSpeed will have tires available very soon. Just waiting on some callbacks and bureaucratic issues...
