Extra Soft Short Springs

Slot.it Extra Soft Short Springs: the finest adjustment for your suspension

When tuning makes the difference between winning and losing tenths per lap, details matter. The Slot.it SICH55D Extra Soft Short Springs are designed for drivers and tuners who need to maximise chassis response, with a soft feel that allows the car to follow the track with millimetric precision.

Function and Performance

The suspension springs determine how the chassis reacts to track irregularities and changes in load during braking and acceleration. An extra soft hardness offers:

• Greater grip on less uniform surfaces, as the chassis better absorbs imperfections.
• A more progressive and smooth response, especially useful in cars with high grip or in configurations where rear tyre wear is to be minimised.
• A feeling of greater contact between the guide and the rail, improving electrical conductivity and stability in slow corners.

The short format makes them specific for Slot.it suspension systems that require this spring length. Each pack includes 8 units, sufficient for several test configurations or to equip multiple chassis at once.

Compatibility

Designed by Slot.it for its own ecosystem of chassis and suspension systems. Before installing them, check on your Slot.it chassis that it requires the short format and extra soft hardness. If you have doubts about which hardness is most suitable for your current setup, Slot.it offers a full range of springs in different lengths and hardnesses that you can combine according to the type of track and race conditions.

Installation and Preparation

Changing springs is a straightforward operation but should be done carefully to avoid damaging the suspension system's anchors:

1. Carefully remove the existing springs, preferably using fine-tipped pliers.
2. Place the new springs ensuring they sit correctly in the chassis mounts.
3. Check the freedom of movement of the system before closing the car.
4. Perform some warm-up laps and observe the behaviour before adjusting other parameters.

Common Mistakes

• Mixing different hardnesses in the same chassis can create asymmetrical and unpredictable behaviour.
• Forcing the spring seat can deform the part and alter the effective hardness.
• Not checking for wear on the springs after many sessions: over time they can lose tension and affect the performance of the setup.

Ideal for…

Club racers looking to fine-tune their setup in each session, tuners working with multiple Slot.it cars who want to always have hardness options on hand, and enthusiasts who enjoy the tuning process as much as the race itself.

Frequently Asked Questions

How many units are included in the SICH55D pack?

The pack includes 8 extra soft short springs, sufficient to equip several chassis or conduct different tuning tests.

What is the difference between an extra soft spring and a standard or hard one?

Hardness determines the resistance the spring offers when compressed. An extra soft spring yields with less force, allowing the chassis to react with greater sensitivity to track irregularities. Harder springs, on the other hand, provide greater stability on smooth tracks and at high speeds.

How do I know if I need the short or long format?

You should consult the specifications of your Slot.it chassis. The spring housing in the suspension system determines which length is compatible. If in doubt, check the chassis documentation or physically compare the length with the springs you already have installed.

Can these springs be used on chassis from other brands?

They are designed for Slot.it suspension systems. They may be compatible with other chassis if the housing dimensions match, but we cannot guarantee compatibility outside the Slot.it ecosystem without prior verification.

How often should I check or change the springs?

It depends on usage. In frequent competition sessions, it is advisable to inspect them every few race days to detect possible loss of tension or deformations. Having a spare pack like this allows for changes at any time without interrupting preparation.
