One thing I noticed with all the wheel and tire packages which are niceNice look with the Legacy rims!
I wanted to see how they would look on the Impreza, too. My buddy traded in his Legacy before I could try them on.
Eg. Oem wrx rim is say 16 lbs
The rims from 17 impreza is between 22-25lbs
Wheel Weight and Unsprung weight
Bearings and suspension will thank you
