FRONT MASTER CYLINDER

The Front Brake Master Cylinder size can be changed to alter the line pressure to the front brake calipers. A larger master 
cylinder will reduce the line pressure to the front brakes, this will shift the brake bias rearwards and increase the pedal effort 
required to lock the front wheels. A smaller master cylinder will do the opposite and increase brake line pressure to the front 
brakes, shifting brake bias forward and reducing required pedal effort. 7 Different master cylinder options are available ranging 
from 15.9 mm / 0.626” (highest line pressure) to 23.8 mm / 0.937” (lowest line pressure).

REAR MASTER CYLINDER

The Rear Brake Master Cylinder size can be changed to alter the line pressure to the rear brake calipers. A larger master cylinder 
will reduce the line pressure to the rear brakes, this will shift the brake bias forwards and increase the pedal effort required to 
lock the rear wheels. A smaller master cylinder will do the opposite and increase brake line pressure to the rear brakes, shifting 
brake bias rearward and reducing required pedal effort. 7 Different master cylinder options are available ranging from 15.9 mm / 
0.626” (highest line pressure) to 23.8 mm / 0.937” (lowest line pressure).

BRAKE PADS

The vehicle’s braking performance can be altered via the Brake Pad Compound. The “Low” setting provides the least friction, 
reducing the effectiveness of the brakes, while “Medium” and “High” provide more friction and increase the effectiveness of the 
brakes while increasing the risk of a brake lockup.

CROSS WEIGHT

The percentage of total vehicle weight in the garage acting across the right front and left rear corners. 50.0% is generally optimal 
for non-oval tracks as this will produce symmetrical handling in both left and right hand corners providing all other chassis settings 
are symmetrical. Higher than 50% cross weight will result in more understeer in left hand corners and increased oversteer in 
right hand corners, cross weight can be adjusted by making changes to the spring perch offsets at each corner of the car. 

IN-CAR DIALS

BRAKE PRESSURE BIAS

Brake Bias is the percentage of braking force that is being sent to the front brakes. Values above 50% result in greater pressure 
in the front brake line relative to the rear brake line which will shift the brake balance forwards increasing the tendency to lock 
up the front tyres but potentially increasing overall stability in braking zones. This should be tuned for both driver preference and 
track conditions to get the optimum braking performance for a given situation. It is important to note that differing combinations 
of master cylinder size will necessitate differing brake pressure bias values, this is because increasing or reducing the split in 
master cylinder size difference between front and rear axles will produce an inherent forward or rearward bias in brake line 
pressure. 

TRACTION CONTROL SWITCH

This option determines if traction control is enabled, allowing you to completely disable the system if desired.
