Sport suspension 1BE

Notes:
The toe-in curve must also be checked in the following cases (in addition
to those specified in table page 44
-10
): A Spring compression
B Spring extension (rebound)
B1 Defined starting position (vehicle at curb weight)
On vehicles with sport suspension, suspension must be extended
20 mm (0.78 in.) to this position.
B2 Vehicle suspension extended 60 mm (2.36 in.) compared to position
B1 page 44

C Toe-in
C1 Toe-in measured in position B1
C2 Toe-in measured in position B2
D Toe-out
V Toe-in curve
S Toe constant, C2 - C1
If the vehicle has been in an accident or sustained damage to the
suspension components and/or bodywork. If the vehicle does not maintain direction of travel over bumps and
when braking or accelerating.
