i have a c320 with 18inch rims with stock suspension that BARELY rubs against the front wheel well when i turn my wheel. if i lower my car with the cupkit, does that mean it will rub even more? i guess it's sort of a physics question. but anything will help, cuz i want to lower my car and not have it tear through my wheel well.

 

it really depends on where it rubs .....

put some masking tape all the way around the fender arch and drive the car to determine exactly where it rubs and then come back here and post the question with all of the needed facts and then we can help you with an answer
