• A negative camber on the rear wheels reduces the tendency of the rear of the vehicle to swing when turning corners.
• In contrast, a positive camber reduces the cornering force on the tyres and is generally not recommended.

a specially shaped steering knuckle, two spherical-head
screws (A) and (B) and two outer plastic set screws (C).
Toadjustthecamber,thespherical-headscrews(A)and

which is inserted through the hole of the set screw (C).

Never use force to tighten the set screws (C), as this may
prevent the wheel suspension from moving freely. How-
ever, the set screws (C) must not be too loose, otherwise
the spherical-head screws and the steering knuckle may
wobble.
