i'm on coilovers.. too much hassle if u ask me..

If i were to get 19" rims.. what would be the best dimensions.. ? cause most 19's are at least 8.5 wide.. and what would be the offset.. it seems quite difficult to find 19" wheels that would fit perfectly on a euro without having a negative camber <-- is this correct.. i'm a bit of a novice so correct me if i'm wrong..

There are 19x8.5 +38 5x114.3 - i'm assuming these will protrude too much as well as my car is lowered and this would be wrong offset.. ?
