High-Performance Coilover Spring (Multi-dimensions)

What you lose by neglecting the spring on your coilover setup

The spring is the most stressed element of your suspension system. Choosing an unsuitable spring or continuing to drive with a fatigued, cracked, or non-compliant spring compromises the very effectiveness of your coilovers. For the owner of a sports vehicle (Renault Sport, Audi S/RS, Porsche...), this neglect leads to:

• Unstable handling: Loss of steering precision and the tire's inability to maintain optimal contact with the road, especially in fast corners or under braking.
• Unpredictable behaviour: The vehicle may react differently between the front and rear, or side-to-side, creating a feeling of insecurity and nullifying the benefit of your caster and camber settings.
• Premature damper wear: A spring whose stiffness (or rate, expressed in $\text{N/mm}$ or $\text{kg/mm}$) is incorrect overloads the damper, drastically reducing its lifespan and its ability to control body movements.

The Optimiz Access Quality Choice for a Perfect Setup

Our springs are designed to offer maximum tuning flexibility and consistent performance. They are available in various dimensions to meet the needs of personalization and repair across a multitude of coilover brands (contact us if you are looking for a specific reference). Our customers' search intent is to find performance springs and suspension parts to achieve optimal road behaviour.

Tuning: Height, Diameter, and Stiffness (Rate)

Each spring is clearly identified by its characteristics. These parameters determine your chassis's reaction:

• Diameter (Inner/Outer): Ensures physical compatibility with the top mount and the body of your coilover damper.
• Height: Influences ride height and spring pre-load.
• Stiffness (Rate): Measure of the force required to compress the spring. A stiffer spring is essential for competition and extreme lightening.

FAQ: Questions you ask about suspension springs

Is this spring compatible with my XYZ coilovers?

Our springs are designed with standardized diameters very common on universal coilovers and performance-oriented brands. To confirm compatibility, you must absolutely check the inner diameter (ID) and outer diameter (OD) of your current springs or the damper perch. Feel free to contact us.

I want to replace a broken spring, is it sufficient to change just one?

We strongly recommend always replacing springs in pairs on the same axle (both front or both rear springs). A new spring and an old spring will never have the same elastic constant or free height, creating an imbalance detrimental to the safety and performance of your sports vehicle.
