ive been messing around withthe ride height on my 2004 vectra sri dti, i managed to get hold of some rear coils springs from a 2005 cdti breeze and fitted them but ended up with the rear lower than the original sri ones, it looks ok but am getting a bitof a clonk on slightly bumpy roads only from the passenger side, rather annoying is the ride height is perfect. heres a some pics. front is lowered 45mm on pi springs and the rear on the cdti breeze springs, as you can see looks pretty level.iphone 5 039 (640x480).jpgiphone 5 042 (640x480).jpgiphone 5 040 (640x480).jpg
