am i going mad?

right, my car is down at the garage i bought it from. The mechanic owns a VR4 himself, now he took it out and said he didn't find any problems. he said the front tires had shouldered a bit, and was going to swap them front to back. Apart from that, he couldn't feel anything wrong with it.

So what the hells going on? am I going mad?, why is the car feeling so different from before?.. Could it have anything to do with the car loosening? shocks getting worn? springs tired? there IS a problem, but nothing out of the ordinary, Apparently. im so confused.. WHY O WHY DOES IT FEEL SO DAMN DIFFERENT.. /twitches

So i was considering upgrading shocks springs, so that i can feel safer horsing it around round abouts etc.. do you guys recommend any?
