My heart sank.
But on hearing that I had kept a hollow 18mm adjustable rear bar fitted, he smiled and said that's your problem..."just throw it away and refit the standard bar!".
Two days later on the same loop, he jumped out with a huge smile and said "that car is an absolute delight....I just wanted to keep driving all week"
Basically the new dampers and springs can do much more of the 'work', much more precisely, and independently from each other.
Stiffer sway bar, less compliance.
So the moral of the story is that even 'mega' dampers can be compromised by a sway bar. My friends view is that ideally in a perfect world you should not need a sway bar, and that it is in itself a very agricultural solution to what is usually a complex problem... in other words its at its most useful at a fine tuning level.
(NB this is only relevant to this car's (rough, fast) road driven development, I'm sure there are many other thoughts and practices with sway bars that are also legitimate)

so what change did the aftermarket bar make? was it stiffer or less stiff?
i've read of a similar sentiment in other suspension posts, where people get fixated on controlling body roll in corners, and start trying to to beef up the sway bars to counteract the physics of body roll without taking any time to understand how it negatively affects specific corner dampening that can have a much larger effect on overall performance.
