I went onto modded euros website looking at Solowerks Coilovers, and I will most likely be ordering a pair of coilovers from them for my 2009 A4 B8 S-Line. Will It make any difference if it is an s-line or no? I'm pretty sure myself it should be fine if they say they work on both the A4 and S4 sedan with quattro. Just making sure and getting a second word of advice. Thanks
