Finally I found the time to fit my SUPLEX kit. Fantastic result - I couldn't even tell if it was a pence or a 10 crown coin (Swedish) I was running over.
Except fitting the kit including springs, Bilstein dampers and the roller bearings I have adjusted the steering rack, fitted new Vesconite bushings (press fit and reamed), new adjustable dampers in the back. I left out the damper blades and have a slight shimmy around 50 mph to work on.
The car is a lot more controllable and has very little kick back and keeps the desired line easily. At higher speeds one can feel the dampers and springs really working in harmony and at lower speeds everything is just a lot softer but still quite firm (as it should be). My rack-and-pinion is very direct and I will fit a steering damper later to help controlling fast straight line driving. Maybe a little less toe in will help also.
All-in-all I think the SUPLEX kit makes the steering, springing and damping work better together. The whole car feel more harmonious.
Thank you all for your input in this thread
