My roommate has these on his 98 Maxima, and they are incredible. Very adjustable and a great ride on the street and track. They were fairly easy to install on his Max, which has a similar setup to the Contours, and the fit and finish on his car is perfect. The color even looks sweet against his car (it's painted Viper blue).
