BBS made their "LM" series wheel, in C-5 applications for a number of years, when the C-5s were "current models". They've been long since discontinued, and the only ones you'll find are used ones, unless someone or some shop stashed a set, forgot about them, and now wants to sell them.
BBS wheels on a C5 are not very common. I think I've seen the LMs leadfoot mentioned once or twice for sale. BBS is a high quality forged aluminum wheel that will definitely hold up to track use. A big part of their business is making racing wheels for big boy toys. Like F1 uses BBS wheels for example. Though the universal truth of aluminum's finite fatigue life still applies that they will eventually wear out. But none of us could probably find their end of life... If you find them they'll be 17" fronts and you'll probably be dissatisfied by the choice of tires.
Honestly I have not seen many BBS wheels on a Corvette of any generation, at least not around here.
Same where I live. I originally had CCW Classics on my C-5, but sadly, had too many issues with the TPMS sensors, which were "glued in place", coming loose. I sold them, and bought a set of the BBS wheels, and have had them ever since, probably close to 12-14 years. I saw one other C-5 with CCWs, IIRC, and it was the same with the BBS wheels....
