Are those prices for the visible carbon fiber rims, or the painted ones?
Assuming it's visible, I note the Canadian MSRP for them when ordering the Z06 with the Z07 package, is $13,794. Your "dealer" prices, add up to $12,095.72 so $1,698 less for the dealer. Of course that doesn't mean dealers will match the $13,794 pricing, especially these days when some tack on *large increases*.
I wonder if pricing will decrease over the years for the carbon fiber rims, assuming they keep pumping them out...and whether pricing will be even better from a GM OEM wholesaler with their typical discounts, if the rims are readily available down the road. Perhaps that's all unrealistic wishful thinking on my part. Time will tell...
**Note: I just talked to a friend who knows next to nothing about C8's and prices. He was talked into paying $160,000 (+ all taxes) for the 2023 Stingray with the 70th anniversary package (3LT convertible) which is over $50,000 more than MSRP. When his dealership couldn't get one due to constraints, they offered him a C8 w/o the anniversary package for the SAME price. He refused...and isn't too happy now that I've told him the MSRP for the car...
