The aesthetic value of your car is not worth compromising your safety or the safety of the other motorists. Use the correct bolt pattern. As a matter of fact, use only JIS, CSA or US DOT standard wheels. If you can, use the same offset and same width to maintain the same scrub radius. Negative offsets shortens the life of the bearings or outer bearings and shortens the service life of the steering components in addition to a less stable vehicle handling.
