NSR soft triangular cradle suspension

The NSR Soft suspension that your triangular mount was asking for

When working seriously with an NSR chassis, every component counts. This suspension in soft version is specifically designed for NSR triangular mounts, references 125x and 126x, and its function is clear: to better absorb track irregularities and keep the guide in constant contact with the rail, especially on circuits with elevated sections or pronounced joints.

Function and performance

The difference between a standard suspension and a soft version lies in the stiffness of the spring or elastic element. A softer response allows the mount to yield more easily to changes in the track plane, resulting in:

• Better guide contact with the rail in areas with elevation changes or track joints.
• Reduction of bounces in chicanes and changes in gradient.
• Greater overall stability of the front end at high-speed conditions.

Compatibility

This suspension is compatible with NSR triangular mounts references 125x and 126x. It is important to verify that the mount installed on your chassis corresponds to these references before proceeding with the installation, as NSR has several types of mounts depending on the chassis model and car configuration.

Installation and preparation

Changing the suspension on an NSR mount is an operation accessible to any enthusiast with basic experience in slot car preparation. Simply remove the mount from the chassis, replace the existing suspension element with this soft version, and reassemble. It is advisable to check that the guide is correctly seated and has vertical movement freedom before putting the car back on the track.

If you are going to combine this change with an adjustment of the braids or the guide itself, it is a good time to review everything together and ensure that the front end responds coherently.

When to choose the soft version?

The soft version fits particularly well on tracks with many joints, uneven surfaces, or where grip is generally low. On very smooth and technical tracks, some tuners prefer firmer versions to gain precision in steering. Knowing your circuit is key to making the right choice.

Frequently asked questions

Is this suspension compatible with all NSR chassis?

Not with all of them. It is designed for NSR triangular mounts with references 125x and 126x. If your chassis uses a different type of mount, consult the corresponding reference in the NSR catalogue.

What is the difference between a soft suspension and a standard one?

The soft version has a softer response, allowing for greater travel of the mount in response to track irregularities. The standard version is stiffer and offers more precision on very smooth surfaces.

Can it be installed without special tools?

Generally yes, although having a pair of fine-tipped pliers and some practice with NSR chassis greatly facilitates the process and prevents damage to the components.

Is it worth changing the suspension if I am already running with the stock one?

It depends on your track and your level of demand. If you notice that the guide loses contact with the rail in certain sections or that the car bounces at the joints, trying a soft suspension is one of the first optimisations we recommend.

The NSR1228 soft suspension for triangular motor mounts (ref. 125x–126x) is a key tuning upgrade for NSR slot cars. Designed to improve guide contact on uneven track surfaces, this soft version enhances front-end stability and reduces bouncing at track joints. A straightforward yet effective improvement for competitive club racing or serious home layouts.
