RC Suspension Tuning Guide – Ride Height
What is Ride Height?
Ride Height is the distance measured from the bottom of the chassis to the ground. This adjustment should always be made with the car in race ready condition, meaning all electronics installed, including the motor and battery. Basically, Ride Height changes the speed of how the car reacts while changing directions. It will be really noticeable in chicanes, or S-turns, where changing directions is crucial.
Ride Height is easily changed on all cars. Some cars have ‘pre-load clips’ on the shocks, others threaded shocks. To change the Ride Height, first place the vehicle on a flat surface (this is crucial!!!). Make sure you have some sort of gauge to keep accurate measurements (simply making the shock collars or pre-load clips even on each side of the car will not work). Some companies sell a Ride Height gauges for a couple bucks, and can be invaluable in this situation. Slide the gauge under the car until one of the steps comes in contact with the bottom of the chassis. This is the Ride Height of this part of the car. Add/remove pre-load clips, or adjust the shock collars, until the desired Ride Height is achieved. Now repeat for the other side of the car, making sure you take the measurement from the exact place you took it from on the other side of the car.
Tuning with Ride Height
For high bite tracks, use a lower Ride Height. For low traction surfaces, raise the car up slightly. Raising the Ride Height will cause the car to roll more, allowing for more traction. Raising the car up will also help in bumpy situations.
