Chassis B. M4 GT3 Std Black

The standard Sideways chassis for the M4 GT3: original spare part, perfect fit

The SWM4A is the standard replacement chassis in black finish that Sideways supplies for its BMW M4 GT3. If, after an accident on track or due to natural wear, your car's chassis has lost geometry, this is the direct replacement you need to restore the original behaviour of the model without compromising any other component of the set.

Function and performance

The chassis is the backbone of the slot car: its rigidity, flatness, and dimensional accuracy determine the alignment of the rear axle, the play of the guide, the load distribution on the tyres, and ultimately, the cornering behaviour. A bent or cracked chassis can result in understeer, oversteer that is difficult to correct with standard adjustments, or even loss of electrical contact. Replacing it with the original part is always the cleanest solution.

Compatibility

This chassis is specifically designed for the BMW M4 GT3 from Sideways in its standard configuration. Before placing your order, check that your car reference corresponds to the Std version; Sideways may offer chassis variants for different motorisation configurations or body styles within the same model family.

Assembly and preparation

As it is an original component from the brand itself, the SWM4A fits directly with the screws, body mounts, motor bracket, and axle supports of the M4 GT3, without the need for adaptations. Nevertheless, take the opportunity to check the condition of the braids, guide, and rear axle bearings before reassembling the set. This is the ideal time to get the car ready.

Common mistakes

• Confusing chassis versions: always verify the exact reference (Std, EVO, etc.) before ordering, as geometry may vary between versions.
• Assembling with screws overly tightened: excessive tightening can deform the new chassis. Adjust with just the right tension to maintain flatness.
• Not checking the rear axle parallelism after assembly: a small misalignment can negate the advantages of the change.

Frequently asked questions

Is this chassis compatible with all versions of the M4 GT3 from Sideways?

It is designed for the standard version (Std). If you have a different variant of the M4 GT3, check the specific chassis reference that corresponds to it before placing your order.

Do I need special tools for the chassis change?

Generally no. The disassembly and assembly of the chassis in slot cars of this range is done with standard precision screwdrivers. However, a flat working surface and a bit of organisation when storing the screws will make the task much easier.

Can I reuse all components from the previous chassis?

Yes. As it is an original replacement, all subcomponents (motor, axle, guide, braids, wheels) transfer directly to the new chassis without modifications.

Does Sideways manufacture chassis in other materials or colours for this model?

This listing corresponds to the standard black finish. Sideways may market other variants; check the updated catalogue if you are looking for a different configuration.
