GENERAL INFORMATION GENERAL INFORMATION Toe InToe Out
Never toe the machine inTry to run 116 to 18 toe out, depending on the amount of bump steerThis measurement should be taken off of the ski's carbide when the machine is supporting its own weight (i.ewith jack stands under the rear bumper and under each trailing arm) for the most accurate measurementWhen setting toe out, in ice racing only, use the inside ski for adjustmentThis will help your sled corner by pulling to the inside of the race track (self steer)Support Sled
Measure at front and rear of carbide
Stock caster can be changed if building new trailing armsTip the spindle angle back to give more camber change throughout the turning radiusThis creates quicker, heavier, more aggressive steering and will help the machine track better in rough portions of the race trackIt is important to note that when caster is altered the stock suspension geometry is changed, resulting in bump steerTo correct this, shim tie rods and change steering arm lengths
