Brett, thanks for the very informative post. Lots of food for thought!

So, I'm just left with the struts and the springs to order. I've looked at the Bilstein B6 option, but I'm leaning towards the Koni FSD's as so many people on here seem to have positive opinions about them. Springs are something else. Rightly or wrongly I'm going to fit the 9 spoke 17" Sport wheels, purely on looks to be honest.
I think it's pretty clear that if I go down this road I'm going to have a very firm ride, so I'm wondering if there's a halfway house where I can calm things down a little- maybe standard SE springs all round? I might even be able to re-use what I've got on at the moment if I go for this option.
The alternative I think is either Sport springs all round or the Eibach +30/00 option, which I understand now is Eibach's at the front with SE or Sport's at the rear?
How hard a ride am I going to get with FSD's, 17" wheels and the Eibach option? Boneshaker or nice firm ride? Difficult one as everyone's ride preference is different I guess....
