The angle of adjustment of the front lip is decisive for aerodynamic performance and correct
aero-balance. For this purpose, the splitter height is set according to the assembly instructions
using the enclosed measuring tool and fixed by tightening the union nut to the specified tightening
torque of 13 Nm (10 ftlb.) and tool T10395/5. If the union nuts are not tightened or not
tightened sufficiently, the inner part may slip out and the front lip rod may fail in the further
course.

Assembly of front lip rods
– Pull front rods (2x) apart. Union nut must never be completely released from the clamping
sleeve/must remain on the clamping sleeve.
