Yellow Speed Racing Gravel Rally Coilovers for the 2005-2007 Subaru Impreza WRX STI (GDB Applied E-G) are purpose-built for gravel rally competition and demanding off-road conditions. Featuring additional lower mount reinforcement, thicker upper mounts when applicable, and approximately 2 inches or more of additional ride height over factory setting with similar to OEM suspension travel, this system is engineered to withstand the extreme demands of rally stages.
The Gravel Rally system offers 1-way damping adjustment, allowing drivers to fine-tune compression and rebound characteristics to match varying terrain conditions. Full-length ride height adjustment via the lower bracket allows stance and weight distribution tuning without compromising suspension travel.
Each Yellow Speed Racing Gravel Rally coilover system is built to order, ensuring precise assembly and quality control for every application.
