Medium hardness suspension spring - medium ø medium

The starting point for fine-tuning your slot car suspension

When we talk about tuning in slot racing, the suspension is one of those factors that makes the difference between a car that handles well in corners and one that sways uncontrollably. The springs are the heart of that system: they regulate how much the chassis yields to bumps, corners, and changes in elevation on the track. The TT926 from Tectime is a medium hardness spring with a medium diameter, a very versatile balance point that works in a wide variety of configurations.

Features and function

• Hardness: medium, the midpoint between extreme stiffness and excessive softness.
• Diameter: medium, compatible with standard suspension mounts on prepared chassis.
• Contents: bag of 4 units.
• Reference: TT926, from the brand Tectime.

Track behaviour and applications

A medium hardness spring offers a solid compromise for most layouts. On circuits with many slow corners, it provides stability without locking the chassis movement. On faster tracks with high-speed corners, it prevents abrupt roll that can cause loss of grip. It is the spring we usually recommend as a starting point before fine-tuning towards a higher or lower hardness based on track feedback.

If your chassis works with adjustable front or rear suspension, starting with a medium hardness spring allows you to have a clear reference before experimenting with more extreme options.

Installation and preparation

The installation of these springs is straightforward: they are fitted into the designated chassis mounts for the suspension. Ensure that the supports are clean and free of dirt before mounting, as any particle can alter the spring's response. The bag includes 4 units, allowing you to change all four suspension support points at once and maintain uniformity in the chassis response.

Ideal for…

• Tuners looking for a neutral starting point for suspension tuning.
• Club racers wanting to improve their car's consistency without radicalising the setup.
• Any chassis with adjustable suspension that accommodates medium diameter springs.

Considerations

Always check the compatibility of the spring diameter with your chassis mounts before installation. Although the medium diameter is the most common, some competition chassis may require specific measurements. Since the bag includes 4 units, it is advisable to renew all springs at the same time to ensure a homogeneous response throughout the chassis.

Frequently asked questions

How many units does the bag contain?

The TT926 bag includes 4 springs, sufficient to equip all suspension points of most chassis at once.

Which chassis is this spring compatible with?

It is compatible with any chassis that has adjustable suspension with a mount for medium diameter springs. For questions about compatibility with your specific chassis, consult our team.

What is the difference between a medium hardness spring and a soft or hard one?

A soft spring allows greater movement of the chassis, which can improve contact with uneven tracks but reduces cornering stability. A hard spring does the opposite: more stiffness, more stability, but less absorption of irregularities. The medium hardness spring is the balance between both extremes and the most versatile for starting to work on tuning.

Can I mix springs of different hardness on the same chassis?

Technically it is possible, but we do not recommend it as a starting point: mixing hardnesses generates asymmetrical responses that complicate the diagnosis of the car's behaviour. It is better to work with homogeneous hardnesses and adjust from there.

How often should I replace the suspension springs?

It depends on usage and track type. In active competition, it is advisable to check them periodically: a fatigued spring progressively loses its original response and can alter the chassis balance without being easily noticeable at first glance.

The Tectime TT926 is a medium hardness, medium diameter suspension spring for slot car chassis, sold in a bag of 4 units. A versatile setup component for club racers and serious hobbyists looking to fine-tune chassis behaviour, improve cornering stability and find the right balance between flex and rigidity on any track layout.
