:: Tuning Tips

Ackermann:

Ackermann is the angle difference between the front wheels when they are turned to steer the car. For minimal tire

slip, it is standard for the inside wheel to steer to a greater angle than the outside wheel. The B5 allows ackermann

adjustments by changing the washer thickness used behind the steering rack ballstuds. The kit setup uses 2mm wash-

ers and is most common for racing conditions. If corner entry steering is too aggressive, try increasing the ackermann

by removing shims from behind the steering rack ballstuds. Increasing the ackermann will increase the angle difference

of the front wheels when steered, resulting in a more stable car on corner entry.

Anti-Roll Bars:

The optional #91468 rear anti-roll bar kit (also called the “swaybar”) allows you to add roll resistance to the rear end

with minimal effect on handling over bumps and jumps. It is an especially helpful tuning item on high-grip tracks

(try the gold bar). The silver and black anti-roll bars are typically used on medium-grip loose tracks.

Trailing Axle:

Trailing axle is the distance from the king pin to the axle that “trails” behind the pin. The B5 includes inserts to allow

adjustments for trailing axle to three positions: 4mm (standard), 3mm, and 2mm. The standard setup uses 4mm

trailing axle for the most stable handling. For more corner entry steering, try the 3mm trailing axle option.

It is important to adjust the ackermann and wheelbase settings to match the trailing axle adjustment. refer to the

chart below for some common settings:
