In theory, I don't see why, with the use of adjustable or shimmed vertical spacers on the steering arms, the Empire Geometric Correction kit can't be used with any ride height or set of shock absorber/spring units, be they Suplex or Spax adjustables.
In pracitice, and being a mere amateur at these things, I find it very hard to differentiate between standard shock absorbers and uprated and vastly more expensive items, in terms of ride quality and road holding, and to know if I truly need to spend money on uyprating them in the first place. Maybe we need to arrange a day where we can meet up somewhere, and drive various cars with different combinations, on a back to back basis, to really see the differences.
