Yup, it makes all the difference. I always find that the Impreza offsets make the wheels look sunken into the fenders too much. Great if you're "layin' frame" like the lowrider boys, but lame if you're doing anything else.Good eye... I am running the same (.19 inch) 5mm spacers on all four corners that I have had on for about two years with my other set of rims. The offset is back to 48mm with them on the STI rims. It makes a nice subtle change.
