Kyosho makes them in blue and red
The holes in the hub allow you to change the roll center of the car and this change also effects how he dog bone plunges into the outdrive and is effects dog bone angles as well.
In general Raising the hub will increase on power traction, decrease traction when breaking. It will also help in rutted conditions. I have not raised my hubs yet but I going to try it at my next club race. The car has worked really well with the hubs low so far so I have not changed that yet.
You should be able to get wings anywhere Kyosho parts are sold.
