I have been upgrading my Electrathon over the summer...Pics to come...

I really wanted to upgrade the wheel discs I made from plastic and held on with zip ties

Do these really help that much ?

I always imagined the air would flow around the tire and the spokes would cause minor drag..... no ?

I don't think they do a whole lot, but I am sure they help some. And they give the car a nice look. If they are using them on the time trial bikes where every last bit of help is needed than I am sure they can't hurt.
