Thankyou for the input guys!

...
So in the end i dissreguarded the 18's wheels & i picked up a near new set of genuine vw Tocatta 17's instead..
I'm going for 225/45's....& something like either dunlop fast response OR a good ol set of Conti's.
Now then...given Eibach are good german quality springs..my original dampers are in servicable shape...so as i'm only going 30mm....i'm sure i'll be ok here methinks.
I'm chuffed with the wheels

Just seen the B8's on ebay. seem cheap enough..
