ST Suspensions Sport Shock & Spring Lowering Kit 30/20mm for BMW 3 Series E90 E91 E92 E93 (2005-2012) Saloon Touring/Estate Coupe Convertible | E9x Fast Road Suspension Upgrade | 316d 318d 320d 323i 325i 330i | Handling Pack | Drop Springs + Dampers

Transform your BMW 3 Series E9x with a proper handling upgrade that delivers confidence, comfort and a purposeful stance. This fixed-rate spring and damper package is engineered to drop the front by approximately 30 mm and the rear by approximately 20 mm, giving your car a lower centre of gravity for sharper turn in, reduced body roll and improved road holding without ruining ride quality.

Why enthusiasts choose this suspension package

• Matched shocks and progressive-rate coils for balanced, predictable handling on British roads
• Approximate 30 mm front and 20 mm rear ride-height reduction for a cleaner, sportier look
• High-strength steel springs with multi-layer coating and final epoxy finish for long-term corrosion resistance
• Temperature-stable twin-tube dampers with model-specific valving and low-friction seals for consistent performance
• OEM-level refinement with a genuine performance feel

Real-world results

We have installed this setup on our own builds and for many customers. Feedback is consistently positive: tighter steering response, flatter cornering and a comfortable daily ride, all while achieving the stance E9x owners want. It is a fantastic upgrade if you want a fast-road suspension that looks right and feels right.
