Product Details
Yellow Speed Racing Premium Competition Coilovers for the 1983-1993 BMW 3 Series (E30) deliver race-ready performance for track day enthusiasts, weekend racers, and club-level competitors without sacrificing daily drivability. Featuring inverted front strut technology for increased rigidity and reduced flex, this 1-way damping adjustable system gives drivers precise control over chassis behavior across varied driving conditions.
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 Premium Comp coilover system is built to order, ensuring precise assembly and quality control for every application.
