Rep Power: 383

Someone i lost all the center caps for my 17 rota subzers, and i cant remember which ones they were , so anyone know? also is it normal for them just to fly off? because i asked rota and they wanted 20 bucks a piece for them , but i found some on ebay that are 20 for all of them bascially, and just wondering if these are them

They flew off? Mine were pretty hard to get on in the first place. I don't think they'd just fly off.
