DIFFERENTIALS
Adjust the characteristics of the differentials by using thinner or thicker silicone oil.
Differential Oil thickness Characteristics
Front
Thinner
· increases steering into corners (off-power)
· if oil is too thin the steering may become inconsistent, especially it can lose forward traction
(and steering) during acceleration out of corners
Thicker
· increases stability into corners during braking
· increases steering on-power at corner exit
Center
Thinner
· front wheels unload more during acceleration
· decreases on-power steering (reduces oversteer)
· easier to drive on rough tracks
· if a high-power engine is used you could waste too much power and sometime “cook” the oil in the
center differential because it “overloads”
Thicker
· more all-wheel drive effect
· better acceleration
· increases on-power steering (reduces understeer)
· better suited on high-bite, smooth tracks
· car can be more nervous to drive especially if a high power engine is used - you might need to be
smooth on the throttle
Rear
Thinner
· increases cornering traction
· increases steering into corner
Thicker
· decreases rear traction while cornering
· reduces wheelspin
Wing position/angle Characteristics
Higher
· increases stability at higher speeds
Lower
· increases stability at lower speeds
Forward
· decreases rear traction
Rearward
· increases rear traction
Flatter angle
· level jumping or nose-diving
Steeper angle
· increases traction at higher speeds
· less nose-diving

CLUTCH
You can adjust the engagement characteristics of the clutch by changing the clutch springs or changing the orientation of the clutch shoes.
Clutch springs
Characteristics
Thinner (0.9mm)
· clutch engages earlier at lower RPM
· more gradual acceleration
· easier to drive but not as aggressive
Thicker (1.0mm)
· clutch engages later at higher RPM
· more sudden acceleration
· car is more aggressive
CLUTCH SHOE ORIENTATION
Adjust the engagement characteristics of the clutch by changing the orientation of the clutch shoes.
Clutch shoe orientation
Characteristics
Trailing shoes
· clutch engages more smoothly
· more ideal for slick track conditions
Leading shoes
· clutch engages more aggressively
· more ideal on high-traction tracks
!
REAR WING
Adjust the position and angle of the rear wing using the different mounting
position of the wing supports.

SILICONE DIFF OIL
XT8 SET-UP
IMPORTANT!
Make equal adjustments on both left and right sides of the rear wing.
Changing the oil in the front differential affects overall steering response.
Changing the oil in the center differential affects the front-to-rear drive.
Changing the oil in the rear differential affects cornering traction and overall steering.
Use only the genuine premium
quality XRAY silicone diff
oils. The differential oils are
availabe in 50ml size in these
viscosities:
CLUTCH SPRINGS
Adjust the engagement characteristics of the clutch by using different clutch springs.
