ST Suspensions XTA Adjustable Coilovers 08-13 BMW 1Series

Adjustable suspension for improved handling and ride control: ST Suspensions XTA Adjustable Coilovers 08-13 BMW 1Series deliver precise chassis tuning and consistent response under varied driving conditions.

Designed and supplied by ST Suspensions, this XTA coilover kit combines a linear race spring setup, adjustable dampers, and aluminum unibal camber-adjustable top mounts to provide repeatable adjustment and targeted control.

• Linear race springs — provide consistent spring rate progression and predictable compression behavior, aiding repeatable cornering balance and suspension tuning.
• Adjustable dampers — allow fine-tuning of compression and rebound to tailor ride firmness and body control for street, track, or mixed use.
• Aluminum unibal camber-adjustable top mounts — enable precise camber correction and maintain suspension geometry under load for improved tire contact and steering accuracy.
• Precise adjustment — full kit-level adjustability permits ride-height and damper setting changes to optimize handling dynamics and driver feedback without replacing components.

Value and functionality:

• Modular tuning — component-level adjustability supports stepwise upgrades and setup changes while retaining core kit compatibility.
• Durability focus — metal top mounts and a race-oriented spring design prioritize long-term mechanical stability during intensive use.
• Application-specific fit — developed for BMW 1Series model years 2008–2013 to ensure correct mounting interfaces and suspension geometry integration.

Use cases:

• Street performance drivers seeking improved turn-in and body-control without compromising day-to-day usability.
• Enthusiasts and club racers who require repeatable suspension settings for lap-by-lap consistency.
• Owners performing suspension setup work who need camber adjustment and damper tunability in a single kit.
