Hi,
Thank you, the garage I take it to have done a great job and I am very pleased.
the Eibach's will bring the front down nicely and the 15mm fill the arches with no issues at all.
I went for 20mm at the rear but if i hadn't had the coilovers fitted would have gone for 30mm. 20mm looks nice at the rear but still doesnt quite fill the arches and you may be disappointed at the drop at the back from the springs, it does still leave quite a gap and gives the nose down look that some like, but wasnt what i was looking for, hence the coilovers.
good luck
