1973 dodge dart 318. it leans way over in turns. I feel every bump in the road. thank you for your time. RR

Evaluate your whole suspension system to see if the rest is in good condition. Bad bushings and shocks can make a car ride and handle like crap.

My dart has stock springs and no swaybar from the factory and rides just fine on 14 inch wheels.
