Show original supplier description

Building upon the foundation of 36 distinct levels of damping adjustment for precise tuning, the Kontrol Sport model incorporates 30% stiffer valving and spring rates. This upgrade results in a more aggressive and direct feel, translating to tighter cornering capabilities and more responsive handling. With front spring rates at 14.0 kg/mm and rear spring rates at 8.7 kg/mm, these coilovers are designed for aggressive street use and intermediate track applications. The system allows for fine-tuning of suspension characteristics to optimize performance based on driving conditions and driver preference. Ksport Kontrol Sport kits are built to order, and customers should anticipate a production and delivery lead time of 2-3 weeks. This kit is specifically designed for 2014-2019 BMW M4 models, with specific fitment noted for convertible variants (F83). Fitment Industries provides a comprehensive search tool to verify compatibility with your specific vehicle year, make, model, trim, drive, engine, and body style. It is crucial to confirm fitment before ordering to prevent potential issues.
