on my 74 Duste360, I upgraded the t-bars with 1.06" and left the factory front sway bar - added urethane bushings to it ! Then added ADDCO 3/4" rear sway bar, used KYB Gas-A-Just shocks on all corners . . . car handled great, and I really did not see or feel change in ride - put over 100k miles on that combination . . .
