70 Dart. Looking for More Castor, QA1 arms or Moog bushings?

I only align to 2*, so I never tried for more cuz it causes a really heavy steering wheel to turn at slow speeds, in parking lots, etc. as a daily driver.
I run lots and lots caster in the RF of my racecar to help turn left.
What is your goal for the car, road-racing ? ?
cheers
