Sure...I'm game! What's the information you've got to share?

I can't believe someone with the alias Christ is giving me flack for being offensive.

Hi All,

My .010" thick aluminum flashing flat disk wheel covers still look good from a distance, with the only apparent defect a dent in one where one of the ME's from work walked up to one and said "These will never last" and kicked the dent in it. This after about 1 and a quarter years of usage. On close inspection one can see 1/16 inch diameter dents from the inside out along the outside diameter, apparently where pea-gravel has gotten between the Prius trim ring and the flashing. I have heard a road debris bounce off them on occaision. The Prius being so quiet at speed, one can hear the drumming noise. But this occurs very rarely. Even with all the pot holes. Its usually when a truck goes buy and hits a pot hole, and the debri goes sideways. But apparently its enough of a glancing blow as to cause no damage.

If these had been hard anodized before installation, there would not be any scratching. AL2O3 is the second hardest material known to man. And hard anodizing puts a layer of that compound on the surface of aluminum.

Does the lip of the wheels have alot of effect on the aerodynamics, because i was wondering if something like this would work.

Centerline smotthies, comes in sizes 16"-24"

Now that's a good lookin' wheel! I hope somebody does some test with those this spring.

Its a good question about the lip though ... hmm I'm wondering the same thing here...

A deep "dish" or lip isn't as good as a smooth wheel cover. Hard to say how much worse that style would be than a flush mounted treatment.

Ok well I am going to make clear plexiglass covers for my new wheels.

Hopefully, they woun't get too scratched by road debris but only time will tell... I wonder how those Mercedes covers would really hold up...

And I am planning on "sticking" them on with some n42 neodymium magnets (probably 3 on each wheel) on the outer part of the rim, and then with three bolts in the center cap... hopefully that will hold up.

Hi!
I searching disc wheel cover. I guess 100$ for 4 disc are very unfair price.
Sure is enough classical plastic wheel cover like on image.
Shame they have only for 13' wheels. I asked shop for 14" for me.
Price for these 13"
are 30$.
