New to this forum but not to 'upgrading' my current/previous cars. I'd like some oppinion/advice on sorting out the suspension on our A4. It's a blach 53 plated B6 car with fully coloured coded lower valence /silver roof rails etc on Audi Sportline17" alloys. Car benefits from some nice extras and even at this mileage we get between 42-45mpg on the motorway. It's done 155k and is in my oppinion one of the best cars family we have ever owned amongst lots of other newer / different marques cars owned previously. One of things bugging me is ride height. Usual rule of thumb at this mileage is change the lot which I don't fall out with but it's such a comfortable ride therefore I'd like something that's S Line height so I'm not interested in coilovers. I still want comfort but not too harsher ride. Question is can I get away with a set of springs and which provide the best comfort...Eibach / H&R / Audi Sportline. I suppose you cannot get 2nd hand Sportline kit? If I can get away with just springs I will unless there's a decent cheaper alternative of spring/damper set up. Wondered if you can get a Sachs/Eibach set up on a budget....I don't want cheap / poor quality which will compromise the car.
