With any wheel Konig develops with Flow Forming Technology, the end result is stronger, lighter and offers greater elongation and shock resistance than a traditional cast design.
Note we STRONGLY recommend our numerous upgraded lug choices with any of our new wheels, stock lugs too short and fat and will scratch these wheels. Unlike the short and fat stock lugs that will result in scratching new wheels, all our replacement lugs have the socket tool bottom on the lug rather than the wheel surface, and are longer for more engagement with stud surface so they also stay tighter.
For this 15x8 +30mm size, an NB with 1.5 negative camber or better typically needs no fender roll for 205/50/15 tire size. NA needs more camber or fender roll for same 205/50 tire size.
