Smoothie center cap issues

[71PICKEMUP]

I need some help! I'm so disappointed with my new Wheel Vintique center caps. I love the style, but after buying five of them, I have only two that I believe "may" stay on the wheels beyond the first trip around the block. The retention rings are too flimsy and deform when trying to pop them onto the wheels. I bought them for my new Wheel Vintique Smoothie wheels. I am sending the caps back to Summit for exchange for a better fitting style, so I'm looking for recommendations for a nice looking center cap that actually fit these wheels and will stay in place.
