Product Details
These Yellow Speed Inverted Pro Street coilovers fit the 1999-2006 BMW 3 Series RWD. They deliver a high-performance street suspension upgrade with inverted front strut technology for increased rigidity and reduced unsprung weight. Featuring 1-way damping adjustment, this system allows drivers to fine-tune ride quality and handling characteristics for both daily driving and spirited street use.
The inverted strut design places the larger-diameter tube at the bottom, closer to the wheel, providing improved lateral stiffness and more precise steering response. Full-length ride height adjustment via the lower bracket allows stance and weight distribution tuning without compromising suspension travel.
Each Yellow Speed Racing Inverted Pro Street coilover system is built to order, ensuring precise assembly and quality control for every application.
