ST XA Adjustable Suspension Kit for BMW F-Series F20 F21 F22 F23 F30 F32

Unlock sharper handling, a cleaner stance and real everyday drivability with the ST XA coil-over suspension. Built with KW Automotive know-how, this height and rebound tunable damper and spring package gives your BMW F-series the precision and confidence you want for fast-road use and the control you need for the odd track day, while keeping comfort intact.

Looking for a BMW F2x or F3x suspension upgrade, sport shocks and springs, ride height adjustable kit, or rebound adjustable dampers for your 1 Series, 2 Series, 3 Series or 4 Series. This is the one enthusiasts pick for road and performance driving. We run this kit ourselves and our customers consistently praise the improved grip, flatter cornering and composed ride quality.

Why this ST XA kit stands out

• On-car rebound tuning via the top of the piston rod for quick fine-tuning
• Wide ride height range for dialling in stance, clearance and balance
• Twin-tube design with pressure-resistant housings for long-term reliability
• Galvanised steel bodies with multi-layer corrosion protection for UK roads
• Real step up over lowering springs or ageing OE dampers for steering feel and stability

Lowering capability

• Front: 25 to 50 mm drop
• Rear: 30 to 55 mm drop

Dial the rebound firmer for crisp turn-in, body control and mid-corner support, or back it off for broken B-roads and long motorway miles. With ride height and rebound both adjustable, you can set your car for daily duty, fast-road blasts and show-winning stance.
