Mitsubishi Lancer EVO Medium Grey Chassis - Inflex 2.0

The Scaleauto Inflex 2.0 Medium Chassis: Control and Consistency for Your Lancer EVO on Track

The SC-6669B is the replacement and tuning chassis that Scaleauto has specifically developed for its Mitsubishi Lancer EVO, integrated within the Inflex 2.0 family. This range of chassis represents the evolution of the brand's controlled flex system: a design philosophy that seeks to balance the structural rigidity necessary for cornering precision and the ability to absorb track irregularities, keeping the car in contact with the track at all times.

Features and Highlights

• Medium Version (Grey): the colour coding in Scaleauto's Inflex 2.0 range indicates the degree of flex of the chassis. Grey corresponds to the Medium version, an intermediate point between the stiffer and more flexible chassis, suitable for a wide range of racing conditions.
• Inflex 2.0 Technology: second generation of Scaleauto's flexible chassis system, with improvements in the geometry of the flex points to provide more predictable and consistent behaviour throughout the session.
• Specific Compatibility: designed for the Scaleauto Mitsubishi Lancer EVO body, ensuring a precise fit without additional modifications.
• Reference SC-6669B: exact manufacturer identification to facilitate ordering as a spare part or as a tuning base.

Function and Performance

In competitive slot racing, the chassis is the element that defines the dynamic character of the car. A chassis that is too rigid can cause traction loss on surfaces with micro-vibrations; one that is excessively flexible can penalise response in fast corners. The Medium version of the Inflex 2.0 family seeks precisely that middle ground: enough absorption to keep the guide settled on the track and the braids in contact with the rails, without sacrificing the lateral rigidity needed to corner confidently.

The Inflex 2.0 system works with controlled flex zones integrated into the chassis structure itself, allowing the car to adapt to track imperfections without compromising the overall geometry. The result is more consistent behaviour lap after lap, especially in long races where driver fatigue makes errors more frequent and the car must be more forgiving.

Compatibility and Assembly

This chassis is designed to fit the Scaleauto Mitsubishi Lancer EVO body. As it is a product from the same brand, compatibility with the motor groups, axles, wheels, and guides of the Scaleauto ecosystem is guaranteed. It is compatible with the Sport track (Scaleauto, Slot.it), although with the appropriate guide it can be adapted to other systems.

The assembly does not require structural modifications: follow the standard assembly process for Scaleauto chassis, respecting the original mounting points of the body.

Ideal for…

• Drivers looking to replace the original chassis of their Scaleauto Lancer EVO after an accident or wear.
• Tuners wanting to try different flex versions (soft, medium, stiff) to adjust the car's behaviour to a specific circuit.
• Clubs and slot racing enthusiasts working with Scaleauto's rally range and seeking consistency and reliability in their setups.

Points to Consider

If you already have the Scaleauto Lancer EVO and want to experiment with different flex configurations, remember that the Inflex 2.0 range offers different versions identified by colour. The choice of the appropriate version depends on the type of circuit, track grip, and your driving style. The Medium (grey) version is a good starting point for most conditions.

Frequently Asked Questions

Which body is this chassis compatible with?

The SC-6669B is specifically designed for the Scaleauto Mitsubishi Lancer EVO body. Compatibility with bodies from other brands or models is not guaranteed without modifications.

What does the "Medium" version mean in the Inflex 2.0 range?

The Medium version indicates an intermediate degree of flex. Scaleauto colour codes the different stiffness levels within the Inflex 2.0 range, with grey being the balanced option between absorbing irregularities and rigidity in corners.

Is it compatible with Scalextric or Ninco track?

The chassis itself is compatible with any track system if the appropriate guide is mounted. For Universal track (Scalextric, Ninco) you will need to adapt the guide; for Sport track (Scaleauto, Slot.it) it fits directly with the brand's components.

Can I use this chassis for club racing?

Yes, as long as your club's regulations allow the use of Inflex 2.0 range chassis. It is a tuning product aimed precisely at drivers looking to optimise their car's performance on track.

Does it include any additional components besides the chassis?

According to reference SC-6669B, the product corresponds to the chassis itself. Please consult the manufacturer's complete data sheet or contact us if you need to confirm whether it includes any additional mounting elements.

The Scaleauto SC-6669B is the Medium Grey Inflex 2.0 replacement chassis for the Mitsubishi Lancer EVO slot car. Part of Scaleauto's controlled-flex chassis range, it delivers a balanced combination of structural rigidity and flex absorption, ideal for Sport track systems. A go-to choice for club racers and slot car builders looking to fine-tune their Lancer EVO's handling characteristics on the track.

Unconfirmed Information

We have not been able to verify whether this chassis includes additional standard components (axles, wheels, guide…) beyond the chassis structure itself. We recommend consulting directly with the manufacturer or our team before placing an order if this information is relevant to your setup.
