    U8333 - Wheel Hex Spacers 0.25, 0.5, 0.75mm - (pk12) U8720 - Alloy Wheel Hex - Mi9 (pr) U8762 - Alloy Narrow Wheel Hex (-0.75mm) - Mi9 (pr) Increasing the rear track width provides more rear stability/less rotation and vice versa.

  • Page 31: Front Toe

    STATIC REAR TOE See Page 11 Step 8b Static rear toe is measured on setup gauges such as SK-600069-01 or AM171040-LE and is the toe angle of the rear wheels when at ride height. The kit setup is 3°. This is adjusted simply by altering the length of the rear turnbuckles shown. More rear static toe in provides more stability, rear grip and forward traction.

  • Page 32: Anti Roll Bars

    ANTI ROLL BARS See Pages 21 & 22 Steps 19a & 19b Anti roll bars allow the tuning of roll stiffness and change the way that the weight is transferred. A stiffer rear roll bar will reduce entry steering but increase on power steering.

  • Page 33: Weight Distribution

    CHASSIS FLEXIBILITY See Page 2 Step 1 High grip conditions=Stiffer chassis setup. Low Grip conditions = Flexible chassis setup. The Alloy chassis is the stiffest option and is best in very high grip conditions. The CF chassis is best in low or medium grip conditions. It will generate more traction.

  • Page 34: Shock Oil

    ACKERMANN See Page 14 Step 14 The front steering arm features two positions for different Ackermann. Position A provides the most Ackermann. This gives a smoother steering feeling and is the best option for an easier to drive car. This is the most common position and prefered by the team for most large outdoor tracks.
