For 2015–2018 Ford Focus RS

The Flatout GR40 Coilovers are engineered for drivers who demand precision, strength, and consistent performance in rally and motorsport competition. With a fully adjustable 0–2 inch ride height range, the GR40 allows fine-tuning of your chassis for tarmac, gravel, or rallycross while maintaining balance, control, and durability under extreme conditions.
