Hi folks got new 18* csl reps today, hope to get them fitted in next couple of weeks when I purchase tyres. I hope to then lower car, what is best make of springs and should I go lowering springs route or performance springs route. My biggest concerns are, how much should I lower by? and Im not sure what springs my car has. For example if I buy 40mm lowering springs and my car has standard springs fitted I should achieve this drop, but if my car has Mtech springs what drop will I achieve.
My car is 320 d ES but has M tech multi function steering wheel, gear knob and black alacantara roof lining, which is why I have the query, im not sure what suspension it has. How could I find out?
