ok, ive today bought a vectra c 1.9 cdti sri on a 56 plate after owning an astra h for 4 years and i have a few questions

1. what would be the best springs to get to lower, ive been looking at pi and eibach but unsure and wheres the best place to buy??

2. are the sri skirts and rear spoilers the same as the vxr styling ones or are they totally different ??

cheers all
