They will actually be a wheel adapter (with lug bosses for your existing lugs and new studs to bolt the wheel up). DO be sure to go with hub-centrics (not lug centrics). Both shown are hub-centric (that ring on the ID is the hub-centric part).
Eibach, MM and H&R are all top notch.
You might have to shave your stock lugs down a little if your wheels dont have an open spot on the backside.
Good luck.
