    Maintain the same wheel widths will ensure a true back to back comparison. The Ignite Series uses a spec wheel width and type for each class. Please refer to the Ignite Series rule book for more information.

  • Page 11: Front Track Width

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 FRONT TRACK WIDTH Front track width can be adjusted by moving spacers to the inside or outside of the wheel. Adjusting front track width can adjust the front responsiveness on turn-in and also the resulting inside rear tire lift.

  • Page 12: Front Torsion Bar

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 FRONT TORSION BAR Front torsion bars allow you to adjust the front end rigidity of your kart. Adjusting the rigidity of the front end allows you to control the stability and responsiveness on corner entry and exit.

  • Page 13: Front Ride Height

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 FRONT RIDE HEIGHT Front ride height can be adjusted for two reasons: to adjust cross weight percentages and to adjust front end responsiveness. A standard Ignite K3 has three adjustment shims on top of the spindle, and three adjustment shims on the bottom of the spindle.

  • Page 14: Caster/Camber/Toe

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 CASTER / CAMBER / TOE Front end geometry is crucial in creating the perfect handling kart. Caster, camber and toe can be adjusted to achieve almost any desired handling characteristic.
  • Page 15 2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 CASTER / CAMBER / TOE (CONT) PROBLEM: The kart is hopping through the center of the corner. SOLUTION: The kart is trying to transfer more weight than the flex in the chassis will allow.
  • Page 16 2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 CASTER / CAMBER / TOE (CONT) PROBLEM: The kart is “darty” and too responsive in the front end. SOLUTION: Decrease the camber (increase the negative camber). This will reduce the contact patch and reduce front end grip levels.

  • Page 17: Rear Track Width

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 REAR TRACK WIDTH Rear track width is described as the measurement of the rear width, from the outside edge of the LR wheel to the outside edge of the RR wheel. Adjusting the rear track width helps determine the rear weight transfer of the kart.

  • Page 18: Rear Wheel Hubs

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 REAR WHEEL HUBS Rear hubs come in variable lengths, which can be used to adjust rear end stiffness and rear track width. If rear track width remains the same, and a longer hub is installed, the leverage point on the axle decreases, causing it to become stiffer and thus working the outside rear tire harder.

  • Page 19: Rear Axle

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 REAR AXLE Rear axle stiffness can be adjusted to create more or less flex in the rear end. Ultimately, the rule of thumb is: softer axles create less grip and stiffer axles create more grip.

  • Page 20: Rear Ride Height

    REAR RIDE HEIGHT Rear ride height can be adjusted to raise or lower the center of gravity toward the rear end of the kart. The Ignite K3 comes with two vertically adjustable axle positions. The standard placement is with the axle in the highest position, which keeps the rear end of the frame low.

  • Page 21: Supplemental Seat Struts

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 SUPPLEMENTAL SEAT STRUTS Adding additional seat struts to a kart can help a driver dictate rigidity towards the rear of the kart. Much like a torsion bar in the front, rear seat struts help direct energy towards the rear of the kart.

  • Page 23 2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 SEAT STYLE AND POSITIONING (CONT) PROBLEM: The kart slides through the corner and oversteers on exit. SOLUTION: Although there are plenty of chassis adjustments to help solve this issue, adjusting the seat can correct the problem as well.

  • Page 24: Chassis Scaling

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 CHASSIS SCALING It is important to scale your chassis when you first purchase it, along with a few other scaling sessions throughout the year. Scaling the kart helps you determine if the kart is mathematically balanced in its neutral position.

  • Page 25: Wet Conditions

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 WET CONDITIONS CONDITIONS Track conditions play a major role in how you should set your kart up for rain. It is important to note if the track is merely damp, retaining water, or entirely submerged.
  • Page 26 2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 WET CONDITIONS (CONT) TIRE PRESSURE Bridgestone YLP: 12-24 PSI cold. Track conditions and ambient temperature play a big part in determining the correct tire pressures for any given run. As the track gets increasingly wet, you will generally increase tire pressures to ensure the tires get to temperature.

  • Page 27: Adjusting For Understeer

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 ADJUSTING FOR UNDERSTEER Understeer can cause many reciprocating effects on chassis handling. It is important to notice where in the corner the understeer is taking place. Most often, a kart will understeer on entry, the driver will put in more steering input, and once the kart grabs become loose on exit.

  • Page 28: Adjusting For Oversteer

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 ADJUSTING FOR OVERSTEER Oversteering, or the rear end being ‘loose’, is when the rear end of the kart has less grip than the front, causing the kart to slide around or through the corner.

  • Page 29: Adjusting For Hopping

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 ADJUSTING FOR HOPPING A driver may feel the kart hop through the middle of the corner, all the way to the exit. This is usually a result of the chassis binding up through the corner. This happens when the chassis does not flex properly through the center of the kart.

  • Page 30: Adjusting For Flat Tight

    2015 IGNITE K3 SET-UP BASELINE SET-UP INFORMATION FOR THE IGNITE K3 ADJUSTING FOR FLAT TIGHT There are different kinds of tight that a driver will need to communicate. Flat tight is when a driver cannot feel the inside rear tire pick up on the entry to a corner, and as a result, the inside rear drags along the racing surface and causes the kart to lose momentum on exit.
