springs to improve handling on different driving surfaces. Before installing, turn off your vehicle and controller and detach the car body.

• You do not always need to upgrade the tie 

rods, dampers, and springs at the same 

time. There may be driving conditions where 

you only want to modify one at a time. 

• Different combinations of tie rods and 

springs will give you optimal driving 

performance. The higher the degree, the 

tighter the turning radius of the car. 

• When upgrading your car, it is best to work 

on a large, level workbench or table.

• To adjust for oversteering, use softer springs 

in the front and stiffer springs in the rear. 

To adjust for understeering, use stiffer 

springs in the front and softer springs in the 

rear.
