Improper wheel hub spacers or none at all. Had the same issue on my Audi and had to order a proper set. Tire companies don't give a crap about proper spacing. They got your money.
Bought direct from Maxton, was all in stock back in April. No idea now. All V2. I put the red striping on to break up the black some. It can be peeled off at any time. Wife kept telling me it looked like the Batmobile.
Install was easy. I did not drill any holes. I used 3M tape and the holes designed into the parts. I have all the hardware. Wasn't sure if I would keep it so I refrained from drilling into my baby. I am on the fence.
