does concave wheels look funny on the front?

[creekwood08]

I haven't seen any concave wheels in person yet but I'm thinking about forge line rb3c wheels on my 69 camaro. Does the concave design allow for very much of a lip on the front wheels. My car will have a DSE sub. I haven't seen any first Gen Camaros with rb3c yet. I've seen pics of ring brothers mustang and 2nd Gen with these wheels. A rendering on here looks really good with them.
