Hi Pete, sorry it has taken me a while to get back to you but I've been waiting to get on to a computer as I hate writing lengthy posts using my phone.
I originally had the strut and damper combo and I didn't think the cabin vibration was anything to shout about really; akin to starting the car in the depths of winter, that kind of vibration.
I then proceeded to fit lots more braces, stripped the car, fitted coilovers, and fitting racing gearbox and engine mounts. At that point the vibration (which is only ever noticeable whilst the car is stationary) was quite prolific, where if you stared at the steering wheel for too long it'd make you ill/ dizzy; but even then I would have never said it was too much. To drive the point home, my wife absolutely hated everything about the car but the cabin vibration was never mentioned in the five years I owned it. Take from that what you will.
My thought process regarding people that do moan about them is that if you want a fast sofa with no character, buy a Golf. :lol:
