Well, as far as my insurance company goes, mag wheels are no problem (ie, the premium is unaffected) however lowering the car IS a big problem. They also have a limit on how many modifications are allowed for different age brackets on drivers younger then 25. Being 20 years old, I'm only allowed 2 aesthetic modifications (absoloute maximum).
Bottom line is, this is something you are going to have to discuss with your insurance company over the phone.
