OK, so I'm thinking of lowering my S-Line (2007 model, sportback TDI 170 quattro) and have some questions:- * Are Eibachs the best choice of springs? * Which part nos fits the S-line? * How much will they lower the car? * Are there any issues with the ABS/quattro when lowering? I'm also considering swapping the 18s for 19s:- * What offset are the Audi 18s? * What width/offset are required when fitting 19s? * What size tyres are recommended? * Do they rub with std suspension and will they rub when lowered?
