Mine aren't ACS, but they are similar (drop, spring rate etc). It's not too harsh at all and it has reduced to nothing that wallowy feeling I was getting when pushing the car hard.......but the standard dampers now can't cope with the stiffer springs and instead I have the occasional bottoming of the bump stops and a whole new bouncy feeling at low speed when the shockers are trying to correct the stiffer suspension!
It's still better (subjectively) from the standard setup, but it can be further improved with shock absorbers to match the springs. I wish I'd done both in the first place to minimise the labour costs.
I should probably grow old gracefully and remember this is a bit heavier and more laid back than my previous rice rocket - it isn't designed for B roads. Where's the fun in having all that power and not being able to use it occasionally, other than in a straight line though?
