I have a 2000 XK8 conv. and just purchased a set of TOYO Proxi 4s and love them! They are extremely quiet and very smooth ridding. I make frequent driving trips through the North GA Mountains and they make the 180 degree turns without slipping or hesitation. I have used TOYOs for years on my GT3000. The Continental Extreme Contacts tend to get a little noisy as the tread wears. I was glad to get rid of my Perelli Zeros that were like driving square tires for the first 5 min.
