ST Coilovers BMW M135i M140i F20 F21

ST Suspensions coilovers for your BMW M Performance are derived from competition and KW's expertise while retaining versatility for everyday use.

Of impeccable quality, these coilovers replace the original components without modification, offering sportier handling with better control of body movements without sacrificing comfort.

• Galvanised treatment and anti-corrosion coating for increased longevity. (VS stainless steel for KW)
  
• Kit supplied complete with spring, elastomer bump stop (VS anodised aluminium on KW), dust boot, travel limiter, etc.
• Front lowering: 20-40 mm
• Rear lowering: 20-40 mm

ST Suspensions offers 3 versions in its STX range; we offer all 3 references, each with at least height adjustment:

• The ST X range includes height adjustment and uses OE-type springs.
• The ST XA range adds damping adjustment to height adjustment, but without the top mounts
  
• The ST XTAplus3 range adds 3-way adjustment and top mounts to the XTA for optimal setup

PLEASE NOTE FOR X DRIVE: the XA is not available for this drivetrain (contact us, we have other solutions)

Mike's tip: "With damping adjustment and threaded bodies but no top mounts, the ST XA kit suits those who want to replace tired original dampers while improving the look. It is also enough to have fun on track 1 or 2 times a year without compromising comfort, keeping the original top mounts. For a more aggressive setup, moving up to the ST XTA+3 makes sense."
