Product Details
The Stance XR1 coilovers for the 2006-2011 BMW 3 Series (E90/E92) are 1-Way adjustable coilovers for daily driving, canyon roads and occasional track days. Every Stance XR1 kit is dyno-tested at the Stance facility in Texas and ships ready to install.
The XR1 line replaces Stance's older Super Sport coilovers with stronger materials, a wider damping adjustment range, and Stance's most durable corrosion-resistant coating to date.
The Stance XR1 coilovers for the E90/E92 3 Series lower the car to an adjustable ride height and keep the factory suspension geometry. Spring rates and damping come preset. Ride height and damping adjust independently for daily driving, autocross or track use.
Features
- 16 levels of damping adjustment, single-knob clicker on each corner
- Inverted monotube front damper with 45mm shaft for racing-grade rigidity
- Digressive valving: sharp low-speed control, smooth high-speed compliance
- Pillowball front top mounts for direct steering response
- Heat-treated chromoly piston rod and CNC-machined T6061 aluminum brackets
- Two-stage zinc + electrodeposited coating, 1,000+ hour salt-spray rated
- 100% rebuildable and revalvable at Stance Suspension's Texas facility
- Swift Springs and helper spring upgrades are available, contact us to add them
16 Levels of Damping Adjustment
The Stance damping clicker gives a positive, audible click for each of the 16 levels of damping adjustment, so you can dial the ride from compliant street settings to firm track settings without losing your reference point. Each corner adjusts independently for precise chassis balance.
Inverted Monotube Damper
Originally developed for professional motorsports, the inverted monotube design uses a 45mm strut shaft for far greater lateral rigidity than competitors' 20mm upright dampers. Less shaft flex means consistent damping under heavy load and longer seal life.
Digressive Damping
Digressive valving produces high damping forces at low shaft velocities for sharp chassis control, and softer forces at high shaft velocities to absorb big bumps without unsettling the car. The result: better feel on transitions, more grip on rough surfaces.
Two-Stage Corrosion-Resistant Coating
Damper bodies are finished with a zinc phosphate pre-treatment plus an electrodeposited polymer coating engineered specifically for Stance coilovers. The finish has cleared 1,000+ hours of salt-spray testing, Stance's most durable corrosion protection to date.
Rebuildable & Revalvable for Life
Stance XR1 coilovers are 100% rebuildable and revalvable. Stance's Texas facility services them and offers custom valving.
