Flat hubcaps?

[GasSavers_DaX]

Anyone ever thought of fabbing up their own smooth wheel hubcaps like the Progress/Vortech landspeed civic? Would this be worth the time?

There was a fellow on an insight message board that wanted to do this. he wanted to make the insight SUPER aerodynamic. Here was his photoshopped proposal for his car:



Someone pointed out however that there needs to be some air to cool the brakes or else they will overheat and break.

I've considered putting wheel skirts on my rear two wheels though like the insight. I'm not sure how much work is involved in something like that, but it would be pretty cool if you ask me

I still say your can do the rear wheel covers easily if you just fab up some fiber glass.

yes i am looking into this heres a link not the expensive. you would also like to lower the car so that the wheel fills up the wheel opening more to keep air from piling up in the wheel well

Damn, not bad, I'm tempted to make some myself though, it'd take some damn fiberglass to my wheels. Good stuff though, really not that expensive.

I just put a set of smooth hubcaps on my escort. I will be watching my mpg's to see if there's an increase. It's hard to find any data on them. I know they use them on experimental cars striving for mileage and also on racing bicycles so I can't help but to think they help, but how much I have no idea.

Heya gene. Do you have any pictures? I'd like to see the hubcaps in action.

I don't know about those. There is a reason that wheels have holes in their design. You need to cool the brakes. If you cover up the wheel like that you better find an alternative way to cool down the brakes.

Lowering the car and using a wind diffuser will give a better mileage gain. Just using the wind diffuser will give a really small gain but the diffuser with a lower car combined will save some money on fuel, not only that but the car will be faster.

They can't help enough to notice. Maybee a few hundreths of a mpg. My wheels are relativly flat already.

I just drove my Ocean Drive run the other way and when I got back I found ice buildup on the leading edge (when they travel forward on the top of the rotation) of the rear wheel hubcap spokes. Seems to me if they are catching ice from the spray from the front wheel or for that matter any flying around from the rear wheel that they have to present some air drag. My Geo had rather smooth hubcaps with oval holes near the outter edge which I like for aerodynamics and am thinking of some simular ones for the xB.
