I run three cars in our open non-magnet unlimited LMP class (a mouthful). The competition is fast and furious and so improvements are by small increments. My
cars are two Toyota GT-1s and a Sloter Zytex. The Toyotas are lighter and the Zytec is more stable in turns. I have been going through each part of the cars
and asking how I could improve it. The Sloter pod is not as precisely made as the SlotIt. It lifts the front of the motor up. I was working on that and
playing with the motor and noticed that the space between the rear bearings was quite narrow and allowed the axle to move back and forth quite a bit if you
measure outside edge of tire to outside edge with one side pulled forward and the other back. This is because of the narrow spacing between the axles. Increse
the spacing and the amount of movement diminishes. The problem is the pod is not adjustable. Solution? Find a set of bearings with closer tolerances.
Problem? Had none but did have a pair that fit the axle very tightly. Dilemna, reduce axle size or bore out the bearing? Reduce axle size as it is easier.
Method? Chuck the axle and hold fine grit paper to the area where the bearing will turn. The bearing fits the axle, but too snuggly but now in the area where
the axle rest I get a very close but smooth fit.
Where does this help the car? I don't notice a difference in the turns, but when the axle is spinning at high revs it does not cause a high speed vibration. Vibration is always bad.
