I would never go cheap coil-overs over springs & dampers.
And given ours only truly get coil-overs on the front...it makes it difficult to choose even good coil-overs over springs & dampers for a daily.
I was pretty low on my third set of springs and I came to dislike the constant worry of potholes and lot entrances...and how to avoid damage. But I did crack the core support last year. So I raised mine, last summer, from 24" to 25-1/4" FTG (fender-to-ground measurement) with a fourth set of springs.
