Best setup for a daily driver

[PGSigns]

Many of us have our trucks with a similar setup as what I have in my truck. It is a 66 long fleet with a crate 350 and a 4L60. Front has 73 to 87 swap with 2" springs, 2 1/2" drop spindles and the 1" sway bar. Rear has 4" springs and a 1" block. Rear has the short adjustable panhard bar. Shocks front and rear are KYB's and no relocators. Power steering and brakes with the master cylinder and proportioning valve from an 88 and up 1500. Now the question is for the suspension guys is where can we make improvements in our daily drivers to make them not only more fun to drive but also improve ride quality since our butts are in them every day. My thoughts are the improvements would be in a longer rear panhard bar and shocks and shock locations. And what about tuning the brake balance to the truck?
