Hi! I just want to let you know that my English is not perfect so dont get mad for some spelling errors. So I bought 2001 A4 and I love it but it needs new suspension. But Im only 18 and I dont know what to do. My dad who is a mechanic says that I need to replace joints and and lower control arms on the front. There is a noise when I break or turn but only sometimes. I was also thinking about "converting" my A4 to S4 but only the look. Some bumpers, grille, maybe lower it a little bit but how to lower it? I know I need new springs and shocks but what else? Thanks for answers!
