As mentioned, I said I'd come back and post here as I'm sure there are plenty of people that don't want to go down the route of coilovers & all of the other potential parts (I've done it before ).
This is purely just a preliminary quick blurt of thoughts as I've not had a chance to go for a 'proper' drive.
So I installed them Thur/Sat, so my set up at this moment is:
Bilstein B6 shocks
Tein S springs
Standard sway bar (with poly bushings)
MPSS Tyres
(this week will see other poly bushings fitted by Sly and a very much required alignment !)
So once the old shocks were off, I compressed them to see how long it would take for the piston rod to extend - the front ones took probably 15+ mins hah, the rears probably about 1-2 mins. So obviously they were for the bin anyway about 20k miles ago I think.
I've not had a real chance to push them as of yet, so I can only comment right this moment on initial impressions of typical daily driving. Which was driving from Surrey back into London.
The ride now rebounds far quicker, so it feels harder but the actual sensation from this is more rounded, it's not harsh at all and certainly gives you a more confident feel.
I've noticed that the tyres remain in contact far better than before, as a couple of joins on a bridge near here would slightly unsettle the car, it doesn't at all now.
So far, so good and I can only echo what the other guys have said.
