Pro Sport Coilovers with 33-Way Adjustable Dampening

The Dynamic Pro Sport Coilovers from Yellow Speed Racing are engineered for the Audi A4 B9 chassis (2017-2024), offering a blend of handling performance and ride comfort. This system provides 33 levels of adjustable dampening, allowing drivers to fine-tune their suspension for anything from daily commuting to spirited track sessions. A key feature is the full-length ride height adjustment capability, which typically allows for a drop of 2.5 inches or more from the stock height. The front spring rate is consistently 10k. For the rear, spring rates vary by drivetrain: 8k for Front Wheel Drive models and 10k for All Wheel Drive (Quattro) variants. The coilovers come equipped with aluminum upper mounts featuring hardened rubber bushings for improved noise, vibration, and harshness (NVH) isolation, and include adjustable camber plates on most applications to enhance steering precision and alignment tuning. Construction includes steel lower brackets for MacPherson strut applications to ensure rigidity, with integrated brake line brackets where applicable. For Double-A Arm strut types, forged alloy aluminum lower brackets are used. Both steel and aluminum brackets receive electroplated or anodized surface treatments to resist corrosion in demanding conditions. The ride height is adjusted by the lower bracket, maximizing suspension travel without compromising shock stroke. Note that these coilovers are built to order, with an estimated lead time of 2-3 weeks. Vehicles equipped with electronic damping may require an EDC cancellation module to prevent dashboard warning lights.
