My Wife's 08 wants to track to the right,so the steering wheel is constantly over to the left to compensate. It doesn't happen with my G5 on the same roads. With the "Uni Body" consruction of todays cars it's a problem with "flex". You can Tie in the strut towers with a brace & also tie the so called frame together with a X brace under the car.My 85 Vette handles like crap with the roof panel out because that ties the the Uni Body together.
