Aero caps or stock Gemini wheels?

I hope they make silver as well as black. Don't particularly care for black wheels.

-Like anything else that induces drag, the plastic hubcaps help at high speeds more than low speeds. They help at 70-100mph more than at speeds like 35-50. The 5-7% efficiency loss without them is going to happen at high speeds. At low speeds the loss is probably more like 1-3%, hardly noticeable. Do you drive really-fast highway speeds often?

5-7% at speed? You have a source for that? Seems pretty high.

Search YouTube. There are a number of videos about this.

WITHOUT Gemini wheel covers:

I just completed a 2k road trip, FW-Denver-Aspen-FW. 60% interstate, 75-80mph. Over Independence Pass TWICE, never a thought about efficiency.

289 wh/mi for the trip. I'll be keeping the Geminis in the storage bag I purchased from Abstract Ocean.

I removed the Aero Caps almost immediately and had my Apollo wheel paint gloss black along with the calipers.

But am intrigued with RIMETRIX's new Aero Cap's for the Model Y and am on their waiting list.

Two days ago my wife "curbed" one of my wheels, which cost me $80 to have repaired.

So now I'm even more interested in the new Aero Caps.

You could try rim protectors, and if you get it in black, may cover up this rash.

I tried the suction cup again and it works if moisten the suction cup with water first.

I bought these too and it worked great. Thanks for tip.

Ditto. I just did about 700 miles to/from Cape Cod MA from NJ. Cruise was set to 73 mph, and I did about 275 wh/mi for the trip (this is just the highway part). No covers on. And I just stopped once each way when the car told me to!
