We were and wanted to come up with a solution. The Flop Stop.! Made from tough and durable ABS plastic the Stop Flop cup holder has a smooth black finish that will fit right in with your Corvette interior Collaspe down the Flop Stop to close the cup holder lid when not in use. Extend the Flop Stop to secure those tall spillable drinks. Note: Will not fit yeti cups or larger coffee mugs. Base diameter of 2.5 inches. Mostly meant for typical soda cans and tall water bottles. The Stop Flop was invented by Corvette enthusiasts as a way to solve the shallow cup holders on the C7. This product is mainly intended for open soda cans or typical water bottles. The base diameter is 2 1/2 inches while the top opening is 2 5/8 inches. The Flop Stop cup holder is built from aircraft grade ABS plastic so it may feel light and maybe filmsy but take comfort in knowing it is tougher than it looks.
