I have just bought a 2010 Insignia SRi (Diesel). I think the standard car sits a little to high and want to lower it 20 mm. I'm based in West Sussex, any idea of a garage/specialist who I can visit to get this done. Or maybe a place I can get the springs?
Any garage will fit new springs for you - it's a couple of hours work maximum.
Eibach Pro-Kit springs are probably a safe bet, should lower it another 15mm or so. Google LMF Vauxhall and give them a call - the guys there will be able to supply the right springs at a good price.
