A bigger T bar will not give a harsher ride when combined with the right shocks. On the Dart I went up from .92s to the 1.03s, combined with Bilsteins, and the car handles the best it has in the 12+ years I've owned it. I also boxed the LCAs, added PST solid tie rod adjusters, adj strut rods, and welded in SFCs. The ride isn't harsh at all.
