In my non-mathematical, non-engineering mind, a trackbar that's too short could potentially raise the driver side due to torque. 3/4"? Not my place or skill level to say.
However, if your front passenger tire is scrubbing on the inside of the fender, an adjustment to the trackbar definitely couldn't hurt. Center that puppy the best you can.
