Lowering range

The ST X coilover system provides a broad, usable range of lowering. On BMW E9x chassis you can typically expect:

Front: 30 to 60 mm lowering (approximately 1.2 to 2.4 inches)
Rear: 25 to 55 mm lowering (approximately 1.0 to 2.2 inches)

This ride height adjustment gives you the flexibility to dial in the perfect look and performance balance for street, fast road or show.

Real-world performance

Designed in conjunction with KW Germany, ST X coilovers deliver a tighter, more composed chassis with clear feedback and confidence on B-roads and motorways alike. Customers love the improved turn-in, reduced body movement and the way the car feels planted without becoming harsh for daily driving. We run and recommend ST coilovers because they work.
