Now that I've decided not to buy the S3 I have another couple of mods in mind. I really liked the ride height on the S3 so would be interested in lowering my car to the same level or slightly lower. I'm also looking at some 10mm spacers to finish it off. I was looking at the DPM site and can't seem to make sense of it. Do I want lowering springs or coilovers? What's the difference? My car has the S-Line suspension which is 10mm lower than the Sport and 25mm lower than standard. The S3 is 10mm lower than my car, so presumably I need to go down 10mm. There are eibach 30mm lowering springs on the dpm site but what do these do? do they lower the car 30mm lower than standard (i.e 5mm lower than S-Line and 5mm higher than S3)? There are also 50/40mm sportline springs which I presume lower it by 40mm from standard? There also seems to be different springs depending on the engine size. Can anybody offer any suggestions on what I need? I see that there is a huge price difference between the coilovers and the lowering springs, so obviously if all I need are the lowering springs that's what I'd prefer to do. I don't want to spend a fortune on something that isn't really going to do anything for me. Also, are the springs something I can fit myself or will I need to bring the car to somebody to do it?
