A few months ago I posted about a different way to mod wheels for racing. Here is the original article for those that want to give it a read: www.redlinederby.com/topic/cone-shaped-wheels/3989#comment-48446
After testing this technique numerous times it resulted in faster runs on the track as it reduces friction greatly. But I noticed that on cars with a wide wheelbase it provided other contact points. 6 to be exact. I used 2 Ferrari Italias for this demonstration since it has a wide wheelbase. In the first pic you can see how the outside-inside coned wheels rub against the track a total of 6 times (including on the wall) Here is picture #1:
Cars are going to ride the track walls on occassions so I had to find a way to eliminate that problem. I then started coning them from the inside-outside instead of from the outside-inside. It worked! If the car decides to ride the wall it will only do so on one contact point per wheel. Now I have 4 contact points in total. This resulted in faster runs since friction was reduced even more. Here is picture #2:
I hope this helps anyone that wants to be faster on the track!
