Hi all,
So I received the “Amazon Premium” versions yesterday so now have all 3 sets that are currently on the market. I hope the information that follows will help you make the right choice for your desires and vehicle.
All measurements and images shown on a 2021 Model Y Performance that is all stock.
Overall thoughts
Tesla OEM: Highest build quality. Lower ⅔ of the flap is a sturdy yet flexible material. Side that faces the wheel is flat. Width covers the entire contact area and profile of the tire to provide maximum protection. Looks a bit like a rally-style flap when on. Front only. Fit is OEM quality.
Amazon “Premium” molded: Soft-touch plastic material. Good build quality. As seen from the pics and photos, these are shorter and wider than the Amazon “Regular” flaps. For the fronts, the width covers the entire contact area and profile of the tire to provide maximum protection. Side that faces the tire is flat. Scratch fairly easily, however shouldn’t affect outward appearance - only on the side that face the wheel. Rears are comparable to the Regular in terms of coverage. Overall fit is slightly worse than Regular but not bad - just small details. Example: the hole for the OEM bolt you use for the fronts isn’t far enough out to account for the diameter of the washer on the bolt (you can still screw it in, just make sure it’s tight). The rear requires drilling into the plastic fender trim for one screw, however you can use double sided tape or just disregard it.
Amazon “Regular” molded (these are also what RPM is selling, and what you find on eBay): More basic plastic construction. For the fronts, these are the narrowest and just barely cover the contact area on stock Pirelli’s but don’t cover the entire tire width. If you have a Michelin PS4AS, Vredestein AS, or another tire with a wider contact patch, these probably wouldn’t cover that entire contact area. However, they extend about an inch farther down than the Premium set, so what you give up in width you gain in length. The side that faces the tire has a repository to collect dirt, debris, snow, etc. This may be good or bad. Fit is good and follows the contours of the car a bit better than Premium. For the rears, fit and width of coverage is comparable to the Premium versions. OEM bolt hole has the same challenge as the Premium fronts. Hang down 3/4" more than the Premiums. No drilling required.

Conclusion
IMO, there is still no perfect mud flap for the Model Y. If someone combined the Amazon Premium width with the Regular length, that would be a winner in my book. OEM delivers the most protection by far if you like the design. But that said, it’s good to have these options out now.
Hope this helps.
