Rear Roll Center
Rear roll center affects on- and off-throttle
situations in all cornering stages.
Lowering rear roll center
• more on-throttle grip
• less grip under braking
• use to avoid traction rolling at
corner entry (increases rear grip)
• use under low traction
conditions
• increases traction, reduces rear
tire wear
Raising rear roll center
• use to avoid traction rolling
mid-corner and corner exit
• reduces rear traction

Adjust the rear roll center by changing the orientation of the rear
pivot pin inserts. Note that when setting the upper inserts to positions
UTO and UBO, you have to shorten the upper arms by turning in the
upper pivot ball; this gives more camber change under suspension
compression and chassis roll.
IMPORTANT! Changing roll-center settings impacts camber and
downstop settings. When changing the lower rear roll center inserts
please note that the default setting of the rear toe-in linkage also
changes. See page 25 for further details.
