Tein Standard Springs 12KG ID 70mm Free Length 150 (Pair)

Starting with a 12kg/mm spring rate, these Tein Standard springs are built for performance applications where a firmer ride is desired. They measure 70mm inside diameter and have a free length of 150mm, making them a popular choice for custom coilover setups or replacing worn-out springs on existing coilover systems. The consistent spring rate helps provide predictable handling and improved body control during spirited driving or track use.

Tein is known for its suspension components, and these springs are well-built to handle the demands of performance driving. The steel construction is solid and designed to maintain its rate over time, resisting fatigue that can lead to a softer ride in lesser springs. When building or rebuilding coilovers, choosing a spring with a known, consistent rate like these ensures your suspension geometry and tuning efforts are based on a reliable foundation.

This pair of springs is a great starting point for tuning your vehicle's suspension. Remember to consult your coilover manufacturer's specifications to ensure these springs are compatible with your specific shock bodies and intended use.
