3D motor mount compatible with NSR OFFSET 1 mm

Sloting Plus 3D Anglewinder Mount: 1 mm Offset to Lower the Centre of Gravity in 1/32 Slot Cars

The motor mount SP610103 from Sloting Plus is a 3D-printed anglewinder mount designed for chassis that use the NSR mounting standard. Its distinguishing feature is the 1 mm offset, which raises the rear axle relative to the motor shaft, allowing the motor-body assembly to sit closer to the track, effectively lowering the car's centre of gravity.

Function and Performance

The offset geometry in an anglewinder mount has a direct effect on the car's dynamic behaviour: by lowering the main mass point, it reduces body roll in corners and increases stability during acceleration and braking phases. With a 1 mm offset, the SP610103 offers a measured and predictable adjustment, particularly useful on technical circuits with tight corners and long straights where traction is critical.

The 3D-printed structure provides controlled flexibility that traditional injected mounts cannot match. This micro-vibration absorption capability translates into more consistent contact between the axle and the bearings, resulting in cleaner and quieter transmission.

Compatibility

• Compatible with the NSR mount standard (anglewinder).
• Designed to accommodate standard brass bushings.
• Compatible with COMBI PLUS (SP053102) bearings from Sloting Plus, which combine brass bushings with internal bearings to minimise friction.

Installation and Preparation

The installation follows the same procedure as any NSR standard mount, requiring no modifications to the chassis or special tools. It is advisable to check the alignment of the rear axle once installed and ensure that the bearings are properly seated before adjusting the crown gear. When using COMBI PLUS bearings, axial adjustment improves significantly, reducing the need for frequent readjustments during the session.

Common Mistakes

• Confusing the mount offset with the crown gear offset: these are independent adjustments. The mount offset affects axle height; the crown gear offset affects the lateral position of the gear.
• Installing bearings without checking the inner diameter: always verify that the chosen bearings are compatible with the diameter of your rear axle.
• Not checking axial play after installation: an axle with too much lateral play can negate the advantages of the offset and generate unwanted vibrations.

Frequently Asked Questions

What is the difference between a mount with 0 mm offset and one with 1 mm offset?

With 0 mm offset, the rear axle and motor shaft are at the same height. With 1 mm offset, the rear axle is raised by 1 mm relative to the motor, allowing the motor and body to sit closer to the track and lowering the car's centre of gravity.

Is this mount exclusive to NSR chassis or can it be used for others?

It is designed to be compatible with the NSR mounting standard. If your chassis accepts NSR mounts, the SP610103 will fit without additional modifications.

Can I use bearings from other brands besides COMBI PLUS?

Yes. The mount accepts standard brass bushings of the appropriate size. The COMBI PLUS from Sloting Plus is the brand's recommended option for its precision and friction reduction, but any brass bushing with the correct measurements will be compatible.

What type of competition is this mount intended for?

It is suitable for both club racing and more demanding setups where fine-tuning axle height and achieving consistency in driving is desired. The 1 mm offset is a common adjustment for circuits with tight corners and significant traction work.

Does 3D printing affect the durability of the part?

The 3D mounts from Sloting Plus are made from high-strength materials designed for competition. The controlled flexibility of the material is a design feature, not a weakness: it absorbs micro-vibrations without compromising the structural rigidity necessary to maintain axle geometry.

The Sloting Plus SP610103 is a 3D-printed anglewinder motor mount compatible with NSR standard chassis, featuring a 1 mm offset that lowers the centre of gravity for improved cornering stability in 1/32 slot car racing. Designed for brass bushings and fully compatible with COMBI PLUS bearings (SP053102), this precision motor pod is a trusted choice for club racers and serious builders looking to fine-tune rear axle height and drivetrain efficiency.
