ST Suspension XA Coilovers for BMW 3 Series E91 Touring/Estate/Wagon & E93 Convertible/Cabriolet (2007-2013) - Height & Rebound Adjustable Lowering Suspension Kit - Adjustable Shocks & Springs - 325i 328i 330i 335i - Part 18220033

Dial in your BMW E91 Estate or E93 Cabriolet with ST XA adjustable sports suspension

Unlock sharp turn-in, confident body control and a purposeful ride height with this ST XA adjustable suspension package, engineered with KW know-how for the E91 Touring and E93 Convertible from 2007 to 2013. This height and rebound tuneable damper and spring set is perfect for fast road use and the occasional track day, giving your 3 Series a precise, planted feel without sacrificing everyday comfort.

We run these on our own builds and have installed them for many customers. Feedback is consistently strong: flatter cornering, improved grip over B-roads, better steering response and a stance you can set exactly how you want it. If you are searching for a serious handling upgrade for 325i, 328i, 330i or 335i E9x models, this is the set-up we recommend.

What you will feel

• Ride height adjustment front and rear for the perfect stance and centre of gravity
• Rebound tuning at the top of the piston rod, so you can go from compliant to firm in seconds
• Twin-tube dampers for consistent performance on UK roads and track
• Galvanised steel struts with multi-layer sealing for strong corrosion protection
• Chromed piston rods and low-friction internals for smooth, predictable damping
• KW engineering heritage for durability, precision and ride quality

Lowering capability

• Front: approx. 30 mm to 61 mm
• Rear: approx. 20 mm to 51 mm

Note: Actual drop depends on vehicle specification. Adjustment is via the continuous thread on the struts and can be set with the kit installed.
