A. Detaching the standard wheels

1 Remove wheel covers on steel disk wheels.

2 Slacken wheel bolts.

3 Raise vehicle.

4 Unscrew wheel bolts.

Note

When unscrewing the final wheel bolt be sure that the wheel does not suddenly tilt off the hub.

5 Remove wheel.

Five of the standard wheel bolts removed must be retained for the spare wheel.

B. Modifications to the body

1 Adjusting the front fender

1.4 Press the side part of the bumper downwards and unscrew the bolts for fender fixing (A and B). Clamp a spacer between fender and body on the left and the right. The bore holes must align to permit troublefree fixing.

1.5 Place one spacer on the left and right between the fender and body in the side area of the bumper.

1.6 Tighten all bolts slightly in accordance with layout. Tighten bolts after a visual inspection.

2 Reworking the body at the front fenders.

2.1 Flattening down front fender flange:
When converting to wider wheels and tyres the inside edges of the front fender must be flattened down to an angle of 110° over the complete wheel cutout.

2.2 If excessive PVC underbody protection has been applied, grind off excess before folding back the fender flange.

2.3 Using a hot air gun carefully heat up outer edges of fender to a maximum of 70° - 80°C.

Note

Do not overheat paint whilst applying heat
(max. 80°C).

2.5 Allow front fender flare to curve smoothly back towards original, unflared line within the marked area (B).

Note

Rectify any damage to paint or underbody protection.

2.6 Grind off side panel to match the reworked fender contour and assemble.

3 Folding back the edge of rear fender

3.1 If excessive PVC underbody protection has been applied, grind off excess before folding back the edge of the fender.

3.2 Using a hot air gun carefully heat up outer edges of fender to a maximum of 70° - 80°C.

Note

Do not overheat paint whilst applying heat
(max. 80°C).

3.3 In the marked area (A), the edge of the fender is flattened down as far as the inside of the fender in several stages.
A plastic hammer must be used to avoid damaging the paint.

Note
Rectify any damage to paint or underbody protection.

3.4 Treat wheel arch again with underbody protection. Spray the folded back fender edges with body cavity preserver.

C. Fitting the special wheels

1 Screw in centering bolts (tool kit) in upper tapped hole of the wheel hub.

2 Put on AMG light alloy wheel and press onto wheel hub.

3 Screw in wheel bolts and tighten positively. The wheel bolts must be dry and free from grease.
Ensure that the wheels are not tensioned by tightening the wheel bolts on one side. (Tighten wheel bolts diagonally in several stages).

Only M12 x 1.5 x 40 mm spherical collar bolts supplied with the rims are to be used for the wheel fixing.

4 Unscrew centering bolt and replace by a wheel bolt.

5 Lower vehicle.

6 Evenly tighten wheel bolts diagonally to a tightening torque of 110 Nm.


AMG light alloy wheel bolts must be retightened after 100-500 km. (Tightening torque 110 Nm).

Note

Fitting snow chains is not permitted.

D. Correction of tyre inflation pressure

The minimum tyre inflation pressures required can be obtained from the tyre inflation pressure table (appendix).

The front axle or rear axle tyre inflation pressures determined are to be noted on the AMG sticker using a waterproof felt tip pen.
Attach sticker to a suitable point on the loading edge of luggage compartment.

Comments:

Tyre inflation details only apply for vehicles with a maximum speed of up to 250 km/h.

The tyre inflation pressure can be reduced by p = 0.1 (bar) per 100 kg reduction in axle load.

Remember that tyre inflation pressure details only apply for cold tyres!

On warm tyres values of up to 0.5 bar higher are permissible. Do not reduce pressure of warm tyres!
Tyre inflation pressure may only be corrected when tyres are cold!

Tyre inflation pressure details relate to the use of permitted maximum speed and permitted axle load.
