well i have a 70 chevelle that seems to a little floaty goin over bumps.i changed the shockswith kyb and it helped alot.the springs look alittle worn out so i am going to replace them as well.i like the stance of the car the way it is right now so i am thinking about 1.5 inch drop springs.my question is what brand to go with,will 1.5 inch drop springs work with stock a arms.and will these help get the floating feeling out of the car.i also plan to change the front sway bar and install a rear sway bar.

It will definitely help to go with a higher spring-rate.
