:: Tuning Tips
Ride Height:
Ride height is the distance from the ground to the bottom of the chassis. The standard front ride height setting is
19mm (Ride Height Gauge #1449).
Check the ride height by lifting up the entire car about 8-12 inches off the bench and drop it. After the suspension
“settles” into place, measure ride height (Ride Height Gauge #1449). Raise or lower the shock collars as necessary.
The rear ride height setting you should use most often is 19mm (Ride Height Gauge#1449).

Wheelbase Adjustment:
You have three options for rear hub spacing, Forward, Middle, & Back.
The kit setting of Middle is the most neutral, and will be used most often.
For improved handling in bumps or rhythm sections, try moving the hubs to the
Back position. Hub forward is typically used on low grip or lots of tight corners.

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 B6 allows ackermann
adjustments by changing the washer thickness used behind the steering rack ballstuds. The kit setup uses 2mm
washers 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.
Shock Mounting Position:
There are two positions for mounting the rear shocks. Mounting the shocks on the front of the arm reduces rear
weight bias. This causes the car to turn quicker and also steer more on-power. Usually this is used on high bite tracks in
order to keep the car steering while applying throttle. Front mounted shocks can only be used with the #91708
lay-down gear box. Mounting the shocks on the rear of the arm increased rear weight bias and keeps the rear end
planted while making the steering radius larger. This setting is typically easier to drive and will produce more rear
traction and can be used with any gear box configuration.
Axle Height:
Axle height is used to keep roll centers similar when large ride height changes are made. As a rule of thumb, high axle
heights are used for lower ride heights (< 20 mm) and low axle heights are used for higher (> 22 mm) ride heights. The
idea is to keep the arms close to level at ride height.
Anti-Roll Bars:
The optional #91735 and 91736 anti-roll bar kits (also called the “swaybar”) allows you to add roll resistance to the
front and /or rear end with minimal effect on handling over bumps and jumps. It is an especially helpful tuning item on
high-grip tracks.
Kickup:
Kickup is the angle the front suspension arm mounts at where the front of the arm is higher than the rear.
The standard kickup angle for the B6 is 25
°
, and is most common. If more corner entry steering is desired, try the
included 30
°
front bulkhead.
