Now who is selling these springs that Mark knows??? Im not selling them thats for sure. To be honest it's hard to say how much they lower the car by. Craig N's car was mega high before and now he has some 50mm Tein springs on his and i'd say it has lowered it close to that. I think other springs lower the car more than 50mm but the thing about the Tein springs is they are very good springs. I'd personally uprate the shocks as when i had them on mine the rear shocks went within a year. I realised when i came to put new suspension on my car. Marks car also has 16" wheels with a 45 profile if i remember correctly. Bourkey
