My 2005 6MT TL has 123,000 miles. I put the A-spec suspension on at about 10,000 miles. With 113,000 miles on the suspension, is it time to start considering replacing the shocks? I just got back from a long trip and noticed the steering felt a bit vague, the tires seemed to tram line more than usual and the ride felt a bit harsher. The Goodyear Eagle GT tires are about halfway done, are properly inflated and have no signs of unusual wear. Thoughts?

Since I may be selling the car in a few months, I was thinking of putting the original suspension back on. Any problems with doing so since they've been sitting in the garage for 4 years?

TIA
