Caster:

Caster describes the angle of the kingpin as it leans toward the rear of the vehicle.  Positive caster means the kingpin 

leans rearward at the top.  The B5 includes two inserts to adjust caster angle at the caster block, 0

°

 and +5

°

.  The total 

caster angle is the sum of the kick-up angle and the caster block angle.  Standard total caster angle for the B5 is 30

°

, 

with 25

°

 kick-up and 5

°

 caster block angle.  For less entry steering and more exit steering, try 0

°

 caster block angle.

Rear Camber:

Camber describes the angle at which the tire and wheel rides when looked at from the back.  Negative camber means 

that the tire leans inward at the top.  A good starting camber setting is -1°.  Adding a small amount of positive camber, 

where the top of the tire is leaning out, will tend to improve straight-line acceleration on loose tracks.

Optional #1719 camber gauge can be used to more accurately set camber.

Front Camber Links:

Changing the length of the camber link is considered a bigger step than 

adjusting the ball end height on the tower.  Shortening the camber link 

(or lowering the ball end) will give the front end less roll and quicken steering 

response.  Lengthening the camber link (or raising the ball end) will give the 

front more roll and slower steering response.  Longer camber links are 

typically used on high grip tracks and shorter links tend to work better on 

medium-grip loose tracks.

Rear Camber Link:

Changing the length of the camber link is considered a bigger step than adjusting 

the ball end height on the rear chassis brace.  Shortening the camber link 

(or lowering the ball end) will give the rear  end less roll and the car will tend to 

accelerate or “square up” better.  Lengthening the camber link (or raising the ball 

end) will give the rear more roll and more cornering grip.  Longer camber links are 

typically used on high grip tracks, while shorter links tend to work better on 

medium grip loose tracks.  The kit setting is the best compromise of cornering grip 

and acceleration.

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.  This can also make the car handle better in 180° turns.

*Spacers to the rear 

will place hubs for-

ward, shortening 

   the wheelbase

Front Camber:

Camber describes the angle at which the tire and wheel rides when 

looked at from the front.  Negative camber means that the tire leans 

inward at the top.  A good starting camber setting is -1°.  Positive camber, 

where the top of the tire is leaning out, is not recommended.  

Optional #1719 camber gauge can be used to more accurately set camber.

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 B5 is 25

°

, and is most common.  If more corner entry steering is desired, try the 

included 30

° 

front bulkhead.  It is important to adjust the bumpsteer to match the kickup angle adjustment.
