2008 b7 suspension??
 

good day all, i own a 2008 b7 a4, 2.0T, s-line with sport suspension. i just bought 18" rs4 replica wheels with a 35 offset. the wheels look great but i wanna lower the front end to close the gap in the wheel well.
how much should i lower it?? keep in mind i live in northern ontario and don't want to go too low, because of the snow in winter months.
Thank you for any suggestions
