Bilstein Suspension B12 Sportline VW Golf Jetta 99-06 99-05

Bilstein Suspension B12 Sportline provides a complete performance suspension solution with extreme lowering between 30–60mm and application-specific damper/spring pairing that delivers predictable, tuned response.

The B12 (Sportline) kit combines Bilstein Performance dampers with Eibach Sportline springs in a matched assembly engineered for each vehicle application. This configuration is intended to deliver consistent damper characteristics across the lowered travel range and preserve the engineered behaviour of the damping system.

• Bilstein Performance dampers — Matched to the Sportline springs to maintain controlled damping across the lowered ride height, ensuring the dampers operate within their designed range.
• Eibach Sportline springs — Provide extreme lowering between 30–60mm (depending on application); the spring rates and lengths are selected to achieve the target ride height while maintaining preload and geometry compatibility.
• Application-specific tuning — Dampers and springs are tuned for each specific vehicle application to preserve the intended dynamic balance and to ensure component interaction is optimized for the lowered specification.
• Complete kit — Supplied as a full set of front and rear dampers and springs (as applicable to the vehicle) to ensure uniform ride height and damping characteristics across the axle set.

Why this matters: the matched Bilstein/Eibach pairing minimizes the need for aftermarket adjustment by providing components engineered to work together, and the application-specific tuning reduces the risk of mismatched spring rates or damping that can compromise performance when lowering a vehicle.
