Spring replacement

Hi guys can anyone help me out? So I'm currently replacing the springs and shock on octavia combi and I'm wanting it to sit slightly lower . I had fitted aftermarket vrs springs to my hatch and it made a real difference but I know the Greenline model sat lower and I'm just wondering how much lower did it sit than the vrs. Im also looking any part numbers so i can cross reference i have tried to google what im looking for but it just becomes a mish mash of numbers and gets confusing. Im just looking either greenline or vrs estate spring part numbers for a manual estate/combi . If anyone can help it would be greatly appreciated.
