AC Schnitzer Coil Spring Kit for BMW 8 Series G14 G15 M850i xDrive

Give your 8 Series the chassis upgrade it deserves. This genuine AC Schnitzer front and rear coil spring set delivers a lower centre of gravity, crisper turn-in and calmer body control while keeping the day-to-day ride exceptionally civilised. Expect a planted feel on British B-roads and motorways, with better traction out of bends and less pitch under braking. We have installed these on customer M850i xDrive builds and the feedback has been consistently glowing for the balance of comfort and performance.

Key advantages

• Reduced body movement for flatter, more stable cornering at speed
• Enhanced traction and weight transfer for stronger drive out of bends
• Noticeably less nose-dive under braking for extra control
• Refined ride quality retained for commuting and long-distance cruising
• Subtle, OEM-plus stance that complements the 8 Series body lines

Why choose this spring kit

Engineered specifically for the M850i xDrive platform, these performance springs are tuned to work with factory dampers, giving you a genuine sport suspension feel without the harshness. The result is a tidy drop in ride height, improved composure over uneven UK roads and a more dynamic driving experience that feels OEM-plus rather than compromised. Our customers love the improved confidence on corner entry and the cleaner, more aggressive stance.
