Another feature of all of our spindles is that they come with 2 steering hole locations. We send all of our karts out with the steering in the outside hole. This gives no ackerman advance and gives us the highest cornering speeds.
The ackerman hole on the inside will put ackerman advance on the inside tire which will make the front steering much more sensitive and also transfers more weight to the rear tires. On dirt, some people will run ackerman only on the left spindle. You should give it a try if your steering is not as good as you would like it to be.
Ackerman steering will also make the kart steer a little harder , for small kids this may be a problem.
The Oval karts have been changed in the rear end of the chassis to allow for ground clearance adjustments. The axle plates have a 2 hole bolt pattern and have 2 sets of holes which will allow the kart to be lowered closer to the ground in 1/4" increments. The purpose for this is to allow you an easy way to compensate for large tire diameter differences from 5" and 6" tires and also for when you are mixing tire brands.
We are installing our "state of the art" caliper mounting bracket which attaches to the cassette; keeping the brake system in perfect alignment no matter what the height, even if one side is lower than the other. We have not found too much merit to wedging the rear end but there is definitely some advantage to keeping a level ride angle.
Martin brakes has developed a new, smaller rear brake system for the Oval 4 cycle karts. We do stock the brake bracket for that size also. The advantage is that the brake is significantly lighter.
