Porsche 917/10K Medium chassis

The Medium chassis from NSR for the Porsche 917/10K: a solid foundation for a track classic

The NSR1613 is the official replacement chassis that NSR allocates for the Porsche 917/10K in its Medium version, finished in black. This piece is designed both to replace a damaged chassis and to provide an additional base for preparing an alternative setup without altering the original assembly.

Function and performance

The chassis is the backbone of the slot car: it determines structural rigidity, weight distribution, ride height, and the mounting geometry of all components. NSR manufactures its chassis from high-strength plastic with controlled flex that allows adaptation to different track types without losing stability in fast corners.

The Medium size indicates the level of flex of the chassis: an intermediate point between the rigid chassis (Hard) and the softer one (Soft), making it the most versatile option for most enthusiasts and for mixed circuits with varying radius corners.

Compatibility

This chassis is specific to the NSR Porsche 917/10K model. As an original spare part from the brand, it fits precisely with the NSR components designed for this body: motor, mount, rear axle, guide, and other platform elements.

Assembly and preparation

As a direct replacement chassis, assembly does not require modifications. It is sufficient to transfer the components from the original car —motor, mount, axles, braids, and guide— to the new base following the same factory assembly process. It is also an ideal starting point for those who want to prepare a second set of mechanics with a different tuning configuration.

Considerations

Before purchasing a replacement chassis, it is advisable to verify that the car model it is intended for is indeed the NSR Porsche 917/10K. NSR offers chassis in different stiffness levels for the same model; if you are looking for more rigidity or softness in handling, consult the Hard or Soft versions of the same reference.

Frequently asked questions

What is the difference between the NSR Medium, Hard, and Soft chassis?

The difference lies in the rigidity of the plastic. The Hard offers greater rigidity and stability on fast tracks with wide corners. The Soft provides more grip by flexing better over uneven track. The Medium is the intermediate point: versatile for most circuits and driving profiles.

Is this chassis compatible with other NSR models apart from the 917/10K?

No. This chassis is specifically designed for the NSR Porsche 917/10K. Other models from the brand have their own chassis references, which are not interchangeable.

Can I mount components from other brands on this chassis?

The NSR chassis is optimised for the brand's own components. While some generic elements may be adapted, it is recommended to use NSR parts to ensure proper fit and geometry.

Is it complicated to change the chassis?

Not particularly. The process involves disassembling the components from the original chassis and transferring them to the new one. With some practice and the right tools, it is an affordable operation for any enthusiast accustomed to maintaining their slot cars.

What type of track is this chassis suitable for?

As a Medium chassis, it adapts well to both Scalextric and Ninco (universal) tracks as well as Scaleauto or Slot.it (Sport) tracks. Its intermediate flex makes it functional in most club and home installations.

The NSR1613 is the official Medium replacement chassis for the NSR Porsche 917/10K slot car, finished in black. Designed for hobbyists and club racers looking for balanced flex and precise geometry, this chassis is the ideal base for tuning or rebuilding your 917/10K. Compatible with NSR components and suitable for both Scalextric-style and Sport-style tracks, it offers a versatile setup for mixed circuits. A reliable NSR spare part for scale slot car racing enthusiasts.
