Another technical videos regarding the offsets of aftermarket wheels. This guy is a ME major graduate and he’s pointing out that aftermarket wheel that have offsets than stock have negative impacts on how car handles. Below is a picture showing that more negative offsets (changing from stock et64 to et50 for example) will actually make the springs softer, which change the car’s overall handling characteristic. However, there r tons of people running aftermarket wheels that have different offsets than stock spec on track. Whether or not it is a theory, I would like hear some expertises’ explanation on this topic. If what he claimed is true, would R spec wheels serve better for our cars in term of handling since they are factory offset specs.
