Hey all,

Picked up a new car this weekend and I am curious if anyone recognizes these rims since I have never seen them before. Also, does anyone know what tool I need to remove the center caps?

Thanks guys!

Actually, looks like I figured it out. I believe they are ACT Ronal LS 4x100. Does anyone know how much these are worth?
