This is a relatively easy install. I purchased these: (Thanks javi_ID4 for finding these)
35.13US $ 18% OFF|Exterior Parts For Volkswagen ID.4 2020 2021 Mudguards block mud and sand to protect cars|Mudguards| - AliExpress

The fronts are held on with 2, T-25 existing screws and one existing push pin trim type faster. The kit comes with new longer #2 Philips screws and push pin fasteners.

The rears are held on with 3 existing T-25 screws. Again, the kit comes with longer #2 Philips screws. You don't have to remove the wheels to do this install. The front wheels can be turned out of the way and the rear can be done with a tip and a 1/4 ratchet. I think they look good and offer some protection.

Very nice! How long did it take for it to arrive?

Amazon also sell it for $10 more and arrives in 8 days.

If I remember correctly it was about 3 weeks to arrive. I was impressed with this kit. Everything fit properly and it looks like it was well engineered.

Nice, are the screw holes all already there for the install?

It's Alibaba/Aliexpress, so this should go without saying, but don't get these if you are in a hurry. I ordered these exact mudguard 10 days ago, and estimated delivery time is the end of June.

Has anyone calculated the increased aerodynamic drag from mudflaps? But then as flaps are typically used in aviation to increase lift perhaps they serve to lighten the ID.4 effectively offsetting same? 🤣

My first bought-new car was a 1977 Toyota Celica GT Liftback and my first 'mod' was mudflaps, so .... ;)

I was hoping the "flaps" would make it fly, but all 4 feet are still planted firmly on the ground ;)

So, in aviation, particularly in jets, the first couple of notches of flaps mostly increase lift but the last couple are mostly about increasing drag so the engines can stay spun up and ready to go. Jets take a long time to come up off idle.

But fly, ID.4, FLY! 🛫

I'm considering adding mudflaps at some point, they were nice on my last car. I have to say after driving around in pouring rain for the last week here in Texas I'm not sure about their need on the ID.4. The car is surprisingly clean. And it's an odd thing to say, but this car is really, really nice to drive in the rain. I can't put my finger on exactly why, but it's just much nicer than other cars in the rain.

VW has obviously done some extensive range-enhancing aerodynamics testing in their design phase and one of the offshoots of same does seem to be a better "laminar flow" of rainwater over/around the planform. The OEM tires are particularly good for rain as well. And of course the low/heavy center of gravity affords a very positive planted feel for more assurance even if 'only' RWD.

The low center of gravity I'm sure helps a lot with handling performance in the rain. I ordered and installed a set of those TOPGRIL flap off of Amazon too. Super easy install, comes with a T25 tool and extra screws which you don't need. I like the look, integrates well with the overall look of the vehicle.

Same here, I installed the TOPGRIL on my ID4

Well, I installed the Amazon TopGril Mud Flaps today and not as much fun as I had hoped. :rolleyes:

Turning the front wheels afforded plenty of access. However when affixing the flaps the bottom screws had a tough time clasping plastic to plastic. I used the longer/thicker Phillips head screws that came in the kit and had enough room for a stout screwdriver. Eventually I got the passenger side to catch but on the driver's side I ultimately had to substitute a plastic pop-screw that you see on other such trim. That actually appears to have worked well (but will be post drive checking it). The front upper screws were no issue.

Ironically despite very cramped tire-fender liner access in the rear those flaps were done in no time as the attachment points are far more positive. I even reused the Torx screws and employed the small right angle Torx/Phillips driver that came in the kit. Three screws on the back (one underneath) added assurance as well.

No jacking nor wheel removal in my effort. That would have benefitted the rears with more space but again not an issue without doing so.

btw: no push pins with the Amazon kit. Just Phillips-washer screws.

No, the Amazon TopGril flaps on the rear wheelwells reused the torx or a new Phillips that’s just underneath. 3 total screws used.

The front units were 2-screw In the wells, only.

Your flaps are somewhat different.

The existing fastner for the bottom attach point wasn't a push pin? View attachment 3788

Sorry you had so much difficulty installing these flaps. Weird that it wasn't a easy job, maybe the panel behind the wheel well isn't lined up correctly?

@Huey52 Could you please post some photos showing the flaps on the car? I'd be interested mainly in seeing a zoomed out shot (of whole car) to get an idea on how the car looks with the flaps. Also, a separate zoomed in photo showing flap plastic color & texture match compared to fender plastic would be good too.

Lastly, any recommendations on size of push pin rivets. I probably just need to buy an assorted kit on Amazon. Thank you!

Yes, I think it was a poor factory retainer/alignment on that driver's-front panel in my case. But a lot of these factory connectors are really only intended to be "one use" to get it quickly built and on down the line.
