Kart Chassis

WHEELS:

Since I am changing the intended purpose of the chassis, I had to also replace the wheel hubs. You should avoid this, as it is quite expensive. The chassis came with 5" wheels with the international bolt pattern. I needed wider wheels, so I had to switch to 6" wheels with the U.S. bolt pattern. I first tried an adapter, but it was not a good fit and required lots of work, so I purchased new wheel hubs. The front wheels hubs are 17mm wheel hubs with the U.S. bolt pattern that I got from Margay. The rear wheel hubs are 40mm wheel hubs with the U.S. bolt pattern that I got from Comet Kart Sales.

It's now time to adjust the wheel hubs. We will not be able to get the ideal results on this chassis because it is planned for use on a clay, oval track. However, the goal is to set the mounting surface of both front hubs to approximately the center of the front spindles. Then, set the rear hubs so that the left side of the left rear wheel is in line with the left side of the left front wheel. This is when an offset chassis would be easier. Now, set the left side of the right rear wheel to the left side of the right front wheel, or as close as possible. Since we could not move the left, rear wheel in as far as it should go, we will probably need to add weight on that corner. This can be determined by weighing the kart and calculating the cross weight. This is only a starting point and should be adjusted at the track according to track conditions and driver's racing style.
