It's not going to improve the ride quality that’s for sure,
Engineers spend countless hours on both suspension geometry and ride heights etc, every car has what called ''roll centre's'' this is a fixed point in space below the car that it rolls or arcs around when it rolls in a corner, it is this 'point' that dictates where and how much the weight transfers either across, longitudinally, diagonally around the car (asd do springs and anti roll bars)
Dampers also need to be matched to springs, rebound within the damper controls the release of the spring after say hitting a bump or exiting the corner, whilst the compression part of the damper could be seen as assisting the spring, of course in adaptive suspension these settings are also altered to assit the spring dependant on the cars attitude and your inputs.
It is very easy to f**k all this up by messing with springs, height and wheels spacers, wheels spacers will affect roll centre's, and the cars Ackermann principle, I know this lot from countless years engineering race cars, when you take a well set up (Factory settings) performance car it can be very difficult to find any quick improvements...............as an eg in 1991 we raced 2 911 Carrera RS's, straight out of the box they were only just over a second off the pace at Donnington, finding that 1.5 seconds is very time consuming and made the cars terrible on the road
