RC Suspension Tuning Guide – Track Width
What is Track Width?
Track Width is measured from the outside edge of the wheels, ie, front track width is from the outside edge of one front wheel to the outside edge of the other front wheel. Track width must be adjusted equally on both side so that the left and right wheels are the same distance from the center of the vehicle. You can do this by placing thin shims between the wheel and axle hex. Unfortunately you can’t adjust track width on vehicles that don’t use a wheel hex adapter, ie, most offroad vehicles.
Tuning with Track Width
Making the track width wider on the front of your car reduces front grip and slows steering response. It also helps reduce traction rolling. Making the front track width narrower increases front grip and quickens steering response.
Making the track width wider on the rear of your car increases rear grip and high speed steering. It also helps reduce traction rolling. Making the rear track width narrower increases rear grip on tighter turns. It also induces a bit of high-speed understeer.
