The Koni 1125 1039 STR.T Kit provides a complete suspension solution for the first-generation Mazdaspeed3. This performance-matched set combines Koni’s signature orange STR.T high-performance dampers with Eibach lowering springs to enhance handling, reduce body roll, and provide a more aggressive stance. By pairing specifically valved dampers with engineered spring rates, this kit eliminates the guesswork of mixing and matching individual components.

Designed as a direct bolt-on replacement for the factory suspension, the STR.T kit offers improved chassis control and feedback for spirited driving while maintaining a composed ride for daily use. The dampers feature fixed-rate performance valving that is optimized for the included Eibach springs, ensuring a balanced and predictable driving experience.
