T.T. I read what you say and i do agree with a lot of what you right especially with the camber changes.
OK, but with the rear suspension, it isn't just changes in camber. The Golf has variable geometery at the rear - which means that the rear toe alters with suspension compression and rebound, and the caster also alters slightly too.
If you had conventional "rigid" wishbone type suspension, with fixed geometery, like on Caterhams, then altering the ride height would be straightforward, and any geometery changes would be linear and fixed rate. But on multi-link suspension designs, you really do need to know what you are doing. It simply isn't good enough just to go to your local suspension place, and get them to swap over the springs and dampers. They actually need to "understand" how minute differences in geometery affect the car, and then develop custom new settings!
Look in my sticky

When i wrote yesterday that i know good ride and feedback can co-exist i remembered afterwards what car i was thinking about - The EVO VIII MR340. Ok stuffed full of electronicsbut it did do the job remarkably well - weighed much the same as the golf and had fairly trick springs dampers - and it was a tall bugger - the caterham talk i only used to demonstrate that the handeling defficiencies (ok bit strong but...) were not down to my crap driving 
Ahhhh - but the Golf and the Evo are chalk and cheese! The Golf is primarily a 5 seat family hatchback, designed to transport 5 peeps, the weekly shop, the annual holiday, transporting granny to and from the care home . . . etc. The GTI/Ed30/.:R32 obviously have to maintain the very same design brief, but with some "tweaking", to give a more "driver" focussed appeal. The Evo, on the otherhand, is basically a homologation special, purely designed to comply with Rally regulations, and then a road car was developed, with the same "rally-like" fundamentals, but with all the electronic gubbins to make it a "safe" road car. Turn off those electronic aids, and you WILL head for the nearest ditch/tree/armco. I actually spent a whole day at RalliArt, near Dudly, a few years back, and "played" in three different Evo IVs and a Gallant VR6 - absolutley fcuking awful cars - the electronic aids were so "in your face", so obtrusive, that, OK whilst handling superbly, took all the skill away from the driver -
Which comes to my next thought.... i have a few ... and for that i am the opinion that it deserves a new thread.....
OK, keep your thoughts flowing . . .
