I own a 99.5 A4 1.8t Avant Quattro, will the suspension off a 2001 S4 Avant fit my car? i want to do a cheap suspension upgrade and i figured the S4 suspension may lower my car and will have higher spring rates but will it fit????

 

Wont lower it much, and you'll be pretty uncomfortable, its made for a way heavier car. Just find a used spring/shock set up.

 

i can't imagine that an s4 avant is much heavier than an a4 avant, only difference being engine size... is the 2.7 bi-turbo that much heavier than a 1.8t???
