I'm new to the forum, and I have a 2003 zx3 premium with the 16" wheels and tires. I bought the car in april, brand new. Since I've had about 500 miles on the car, it has been back to the dealer on two seperate occasions to check the alignment. When I go over certain types of bumps, especially manhole covers, it feels like the front end of the car wants to go one way and the back another. The steering wheel is ****ed to the right and the car pulls left, even accounting for the crown in the road. I have heard the Firestone Firehawks on the car have a poor ride quality, but this is ridiculous. Any suggestions? thanks.
