Chassis 9x8 LmdH / Hypercar Grey - Medium

The medium-hard grey chassis that brings the Scaleauto 9x8 LmdH to life

The SC-6675B is the official chassis from Scaleauto for the 9x8 LmdH / Hypercar body, made from injection-moulded plastic with a minimum thickness of just 0.65 mm. This reduced thickness is no coincidence: the less material, the less unsprung weight and better suspension response in corners. The grey – medium hardness version sits in the middle of Scaleauto's hardness range, making it a versatile option for both home circuits and Sport club tracks.

Technical specifications

• Material and thickness: injection-moulded plastic with a minimum thickness of 0.65 mm.
• Colour / hardness: grey – medium hardness.
• Motor compatibility: prepared for RT4 motor mount.
• Front axle: height adjustable using M2.5 allen screws, allowing modification of front ground clearance without changing parts.
• Suspension points: 6 optional points for the pod, offering different suspension configurations based on driving style and track type.
• Body fixing: adjustment of front and rear body using M2.5 screws.

Medium hardness: when is it the right choice?

In slot racing, the flexibility of the chassis directly influences how the car absorbs changes in elevation, track joints, and vibrations on straights. A chassis that is too rigid can lose grip on tracks with imperfections; one that is too soft generates unpredictable behaviour in fast corners. The medium hardness of the SC-6675B balances both situations:

• Performs well on Sport tracks with regular surfaces.
• Better absorbs joints than a hard version, without losing precision in steering.
• Facilitates initial setup sessions before deciding if a softer or stiffer chassis is needed.

Assembly and preparation

The height adjustment of the front axle using M2.5 allen screws is one of the strengths of this chassis. It allows for precise ground clearance (ride height) adjustments without the need for spacers or additional parts. The 6 optional suspension points for the pod provide room to experiment with different degrees of lateral movement, something that the most demanding tuners will appreciate.

The front and rear body fixing with M2.5 screws ensures that the 9x8 body is firmly secured and aligned, avoiding play that could affect track behaviour or the visual appearance of the model.

Ideal for…

• Owners of the Scaleauto 9x8 LmdH / Hypercar kit or car looking for a replacement chassis or wanting to try a different hardness.
• Club tuners working with the RT4 motor who want a balanced starting point.
• Enthusiasts starting in chassis tuning who prefer a medium hardness before moving to more extreme versions.

Frequently asked questions

Which body is this chassis compatible with?

It is specifically designed for the Scaleauto 9x8 LmdH / Hypercar body. The front and rear fixing is done with M2.5 screws included in the chassis's anchoring system.

What motor does the SC-6675B support?

The chassis is prepared for the Scaleauto RT4 motor mount. Check the range of motors compatible with this mount before purchasing a new one.

How does medium hardness differ from soft or hard?

Medium hardness offers balanced behaviour: more control than a soft chassis in fast corners and better absorption of imperfections than a rigid one. It is the usual starting option before fine-tuning with more extreme versions based on circuit characteristics.

Is it compatible with Scalextric or Ninco track?

Scaleauto works on Sport track, the same system used by Slot.it. It is compatible with Sport track. For universal track (Scalextric, Ninco), the guide and braids of the mounted car would need to be checked, not the chassis itself.

Can I also adjust the rear ground clearance?

The manufacturer's description specifies the height adjustment of the front axle using M2.5 allen screws. For the rear axle, adjustment is usually done through the pod and the optional suspension points included in the chassis.

Does it come with the M2.5 allen screws included?

Scaleauto does not specify in the official description whether the screws are included. We recommend confirming this with us before placing the order if you need additional screws.
