Cast. I've only had the car for 6 months so I just had them swap over the original tires and TPMS sensors. As for liking them, I've only had them on for the weekend but no complaints so far.
I've narrowed my wheel choices down to two options (for the time being). Both are 18x8, 40mm offsets.
I've got a white 2.5 Limited
GWG Flare with Blue undercut
Mach ME1 in Hyper Silver
