Yep, tipping your shocks at an angle does reduce that shocks ability to control the tire. No two ways about it.
Low lifts, flexy suspensions and the desire to keep the shocks out of the bed be it a blazer or whatever else all contribute to the end result of inboarding the shocks.
Inboarding the shocks works well for some and is probably not the answer for some others. On our R and D truck it worked awesome! It was a 79 chevy 3/4 ton pickup. Light in the tail.
Alot of your cheapo shocks are valved "stiffer" than they need to be for our purposes. Maybe not stiff enough for some other purposes. Two rigs doing exactly the same thing with exactly the same setup can end up with two entirely different shocks based on nothing more than what the driver likes to "feel".
After everything else you'll have to figure out what works best for your rig, your driving style, and what you do with your rig!
