hi, can somebody pls. explain to me the basics on what to do when changing your car's wheels. i mean the lowering, suspensions, and the shock absorber stuffs. what's to and not to do. i'm really not familliar to those things (shock absorber, coilover, suspensions, etc.) so i would really be glad if someone would take the time out to explain these things to me. btw, i'm changing my wheels from 15 to 17. thanks again.
