Lol, i have 2 different pics then you sir, A spec is a red rim of i believe a Ford GT, and B spec i can't recall.
Pretty neat to see this actually...![]()
I'm pretty sure my A-Spec has always been a chrome rim, but I did notice my B-Spec changed yesterday. I really don't think it's been changing with level though.

One other observation, there is enough space above the Endurance Series events for another tab to open up. Not that there will be, but as in GT1 & GT2 there was hidden events such as the Hi res version of SSR11 in GT1 & the Events Generator in GT2. The space could also be left for future events yet to be added by PD, just speculation.
