Conversation Between '08C4S and eminto

My 2005 Carrera C2 had the steering pump and rack replaced ..... anyways, prior to this change my steering felt loose at high speeds and now there is no change. Basically the faster I go the more I need to correct the car on the road. I have had 3 alligments with no results. The car has 53000 miles... any suggestions .... bushing... suspensions?
