Basic Chassis Tuning
If front end of kart is not gripping in corners (understeering):
Move out one wheel spacer on both spindles.
If front of kart becomes too wide, move wheels back to original spacing and change
caster/camber adjusters from II/II to II/III or III/III (be sure to re-check toe settings).
Fit shorter hubs to rear axle. Be sure to measure from the hub face that meets the wheel to the
chassis first (typically around 8-3/4”), so you can keep the same rear width measurement.
Raise the hot rear tire pressures .5 to 1 psi.
Remove seat struts, if fitted.
Use a softer rear axle.
If back end is sliding (loose) at entrance of the corner or there is too much front bite:
Move in one wheel spacer on both spindles.
Lower .5 to 1 psi in the rear tires.
Move weight away from the front of the kart.
Lower the front of the chassis (be sure to re-check toe settings).
Put less caster in. Adjusters at I/II or I/I (be sure to re-check toe settings).
Tighten the front bumper, if not already tight.
Check to make sure your toe is set properly. 1-1.5mm on each side, while the kart is on a stand
(slightly more for heavier drivers).
Fit a stiffer axle.
Fit longer rear hubs. Be sure to measure from the hub face that meets the wheel to the chassis
first (typically around 8-3/4”), so you can keep the same rear width measurement.
Fit seat struts (maximum of 4 total).
Tighten rear bumper if not already tight.
Raise rear ride height.
The kart is hopping in the corners:
Set the rear track as close to the legal limit, if not already there.
Fit shorter wheel hubs on the axle. Be sure to measure from the hub face that meets the wheel
to the chassis first (maximum legal width will be around 8-7/8” at the hub face), so you can keep
the same rear width measurement.
Raise the air pressure in the rear tires by .5 to 1 psi.
Lower any ballast to a lower vertical position (especially in the rear of the kart). This includes
the driver. In some very high grip situations, moving the seat forward, then angling the rear of
the seat down will greatly lower the kart’s center of gravity (cg).
Lower the rear ride height to the maximum, if not already done.
Change to a softer axle.
Remove seat struts.
