Stance XR1 Coilover Set BMW M5 E39 1998-2003 Stance

Originally designed for use in professional motorsports, inverted monotube technology has many advantages over upright monotube dampers. Our 45mm strut shaft offers increased lateral rigidity over competitor’s upright dampers that use 20mm shafts. If the shaft is not stiff enough it can cause the damper to bind under heavy loads and limit the suspension travel – leading to premature wear on the shaft seals & piston bands, causing oil leakage. STANCE inverted monotube dampers offer exceptional ride comfort without sacrificing performance.

Our piston has been developed to deliver a large range yet responsive adjustments. Even with this large adjustment range, each click is even and precise to provide excellent fine tuning ability. Winning races has taught us that compliance is key, even for competition setups. Our know how allowed us to fine tune the valving balance providing you the ability to go from compliant & forgiving to firm & responsive with just a few clicks of the knob.

Digressive valving produces high damping forces at low shaft velocities & softer damping forces at high shaft velocities. Low speed damping gives better control of the chassis movement & provides quicker feedback to the driver, enhancing overall feel & confidence on the road & track. Digressive high speed valving profile blows off big bumps forces for smooth response, giving optimal chassis balance for maximum grip.

The Stance damping adjuster knob, or “Clicker”, is designed to offer an easy and convenient way to adjust the damping of your coilover. Our heavy-duty adjuster gives a very positive “click” for each of the 16 levels of adjustment, making it easy to keep track of your personalized settings.

Our coilovers are tested on each and every application to guarantee a perfect fit for your vehicle. Everything from wheel clearances to ride height adjustment is taken into account during the design process to make sure you experience a hassle free install of your new Stance coilovers.

Chromoly steel STANCE piston rods have been heat treated, chrome plated and machined to precise tolerances providing consistent reliable performance.

STANCE monotube dampers offer larger oil capacity and a superior piston diameter compared to a twin-tube design. In our monotube dampers, the oil and charged nitrogen are separated by a free floating piston, which minimizes aeration and fade. These features allow for greater heat dissipation, fade resistance and consistent damping force.

Rubber Dust Boots are designed to protect the piston shaft from road contaminants.

Rubber Bump Stops are utilized on all STANCE dampers to improve ride comfort and protect the damper from bottoming out.

XR1 uses Electrodeposition polymer coating engineered specifically for our coilovers. Damper cases go through additional zinc phosphate pre treatment before our special formulated coating to deliver the ultimate corrosion protection. New and improved coating has exceeded 1000+ hrs of salt spray test, making it our most durable coating!

Offered on strut-type applications, CAD-designed brackets are reinforced to withstand the most rigorous loads for racing. Height can be adjusted separately from the spring without sacrificing damper stroke.
