BMW M8 GTLM Chassis - Standard Hard

The chassis that keeps the Scaleauto BMW M8 GTLM finely tuned to the millimetre

The SC-6679A is the official replacement and tuning chassis from Scaleauto for their BMW M8 GTLM, made from injection-moulded plastic with a minimal thickness of 0.65 mm to minimise weight without sacrificing stiffness. The Standard Hard version is designed for those seeking predictable and consistent track behaviour, especially in configurations with the RT3 motor.

Technical features

• Material: injection-moulded plastic with a thickness of 0.65 mm, black colour.
• Hardness: Standard Hard, for greater stability and uniform response.
• Motor compatibility: specific support for RT3 motor.
• Front axle: height adjustable via M2.5 allen screws.
• Pod: 6 optional suspension points to customise suspension geometry.
• Body: adjustment of front and rear sections via M2.5 screws.

Function and performance

The minimal thickness of the injection-moulded plastic is a deliberate engineering decision: to reduce unsprung mass and lower the centre of gravity of the assembly. In club racing, those grams of difference translate into tighter lap times and a more responsive feel in fast corners.

The Standard Hard hardness of this chassis distinguishes it from the softer versions in the Scaleauto catalogue. A stiffer chassis transfers the car's movements to the guide with greater fidelity, which particularly benefits drivers who prefer a clean driving point without excessive lateral flex, albeit at the cost of slightly less grip on tracks with many irregularities.

Compatibility and assembly

This chassis is specifically designed for the Scaleauto BMW M8 GTLM body. The adjustment of the front and rear body is done with M2.5 screws, allowing for quick disassemblies in the pit without special tools beyond the corresponding allen key.

The 6 optional suspension points for the pod open up a range of configurations that allow for adapting the car's geometry to different types of track or to each driver's personal preferences. This flexibility makes the SC-6679A a chassis suitable for both competitive preparation and recreational tuning.

Ideal for…

• Drivers competing with the Scaleauto BMW M8 GTLM who need a replacement or tuning chassis.
• Enthusiasts wanting to try different chassis hardnesses to optimise their car's performance on Sport track (Scaleauto, Slot.it).
• Tuners looking to extract maximum performance from the mechanical assembly without modifying the original body.

Points to consider

Before mounting the chassis, check that the M2.5 screws are in good condition and that the front axle is perfectly level after height adjustment. A small imbalance in the front axle can result in erratic behaviour in slower corners. If you are changing the chassis hardness from what you were previously using, dedicate a few sessions to readjusting the guide position and the braid load to get the most out of the new configuration.

Frequently asked questions

What is the difference between the Standard Hard chassis and the softer chassis from Scaleauto?

The hardness of the plastic determines how much the chassis flexes during operation. A harder chassis, like this Standard Hard, offers greater consistency in load transfer and a more predictable behaviour, although it may be somewhat more demanding on tracks with many surface irregularities. Softer chassis absorb those imperfections better at the cost of some precision.

Is it compatible with any Scaleauto motor?

According to the information provided by the manufacturer, the motor support of this chassis is optimised for the RT3 motor. Consult with Scaleauto or with us before mounting a different motor to ensure mechanical compatibility.

Does it work on Scalextric track or only on Sport track?

This chassis is part of the Scaleauto car ecosystem, designed for Sport track (Scaleauto, Slot.it). The guide and the width of the assembly are optimised for that type of track. It can run on universal track (Scalextric, Ninco) with the appropriate adapters, but its design is oriented towards Sport track.

Can I use this chassis as a base for competition preparation?

Yes. The 6 optional suspension points for the pod and the fine adjustment of the front axle make it a very versatile base for tuning. It is a common starting point for tuners working with the Scaleauto BMW M8 GTLM in club categories.

Does the chassis include screws, axle or any additional accessories?

The manufacturer's information does not specify that additional accessories are included with the chassis. If you need M2.5 screws or axles, consult them as independent spare parts.

The Scaleauto SC-6679A is the official replacement and tuning chassis for the BMW M8 GTLM slot car, featuring injection-moulded plastic at just 0.65 mm thickness in Standard Hard version. Designed for Sport track systems, it supports the RT3 motor, offers height-adjustable front axle via M2.5 allen screws, and includes six optional suspension points for the pod. A go-to choice for club racing preparation and slot car tuning enthusiasts looking for consistent lap times and precise handling.
