Chassis P-963 GTP / Hypercar Black - Standard Hard

The chassis that tunes your Porsche 963 LMDH GTP for the track

The SC-6673A chassis from Scaleauto is the reference piece for those who are deeply involved in preparing the Porsche 963 LMDH GTP. Made from injection-moulded plastic with a minimum thickness of 0.65 mm, in black and with standard hardness, it offers the right balance between structural rigidity and dynamic behaviour on Sport track.

Features and highlights

• 0.65 mm thick injection-moulded plastic: minimal weight without compromising the integrity of the assembly.
• Black colour, standard hardness: designed for general use and as a starting point for tuning.
• RT4 motor mount: compatible with Scaleauto's RT4 motor.
• Adjustable front axle height using M2.5 allen screws: allows for precise adjustment of the front geometry.
• 6 optional suspension points for the motor pod: expands configuration possibilities according to the demands of each circuit.
• Front and rear body adjustment using M2.5 screws: secure and repeatable fixing in each assembly.

Function and performance

The choice of chassis is one of the most decisive decisions in the preparation of a competition slot car. A thickness of 0.65 mm reduces the total weight of the assembly and lowers the centre of gravity, enhancing stability in corners. The standard hardness is the most versatile option: it performs well on mixed circuits and is the usual starting point before testing softer or harder versions depending on the track type and racing conditions.

The height adjustment of the front axle is particularly valuable on circuits with elevation changes or when optimising the guide's attack angle. The 6 optional suspension points for the motor pod add a level of customisation that the most demanding preparers will know how to exploit.

Compatibility

This chassis is specifically designed for the Porsche 963 LMDH GTP model from Scaleauto and is compatible with the RT4 motor. It integrates into the Scaleauto tuning ecosystem, a brand with a wide range of spare parts and tuning options for its own models.

Assembly and preparation

The assembly is straightforward for those already experienced with injection-moulded plastic chassis. It is advisable to check the flatness of the chassis before first use and to ensure the correct tightening of the M2.5 screws without over-tightening, to avoid compromising the plastic. If using the optional suspension points for the motor pod, it is recommended to test different configurations in practice sessions before finalising the setup for competition.

Ideal for…

Preparers and club drivers looking for a solid base to build or repair their Scaleauto Porsche 963 LMDH GTP, with real adjustment margin and the possibility to evolve the configuration according to the circuit and championship regulations.

Frequently asked questions

What is the difference between standard hardness and other available hardnesses?

Standard hardness is the most balanced: it offers good rigidity for most circuits and conditions. Softer chassis provide more flex and usually improve grip on technical tracks, while harder ones are preferred on fast circuits with few slow corners. The standard is the ideal starting point for tuning.

Is this chassis compatible with motors other than the RT4?

According to the manufacturer's information, the SC-6673A chassis is designed with specific support for Scaleauto's RT4 motor. We cannot confirm compatibility with other motors without data from the manufacturer to support it.

Can it be used on Scalextric or Ninco track (universal track)?

This chassis is part of the Scaleauto ecosystem, aimed at Sport track (Scaleauto, Slot.it). Its use on universal track (Scalextric, Ninco) will depend on the guide and braids mounted, but the chassis itself does not limit the type of track.

Are M2.5 screws included?

The manufacturer's description does not specify whether screws are included in the package. We recommend checking the exact contents of the product before assembly.

What advantage do the 6 optional suspension points for the motor pod provide?

They allow for adjusting the torsional rigidity of the chassis according to the circuit, varying the number and position of the active points. It is an advanced tuning tool to optimise the car's behaviour based on the layout.

The Scaleauto SC-6673A is an injection-moulded chassis in black with standard hardness, purpose-built for the Porsche 963 LMDH GTP slot car. At just 0.65 mm thick, it minimises weight while offering a fully adjustable front axle (M2.5 allen screws), six optional suspension points for the motor pod, and body fixing screws front and rear. Compatible with the RT4 motor, it is a key tuning component for club racers and slot car builders looking to fine-tune their Hypercar GTP build on Sport track systems.
