Product Details

This KONI STR.T Kit fits the 1997-2003 BMW 540i Sedan. The KONI STR.T Kit for the 1997-2003 BMW 540i Sedan (E39) is a complete bolt-on suspension package: four matched KONI STR.T shocks paired with a set of Eibach Pro-Kit lowering springs. The result is a 25-35 mm drop, tighter handling response, and a noticeably more composed ride than the factory setup.

STR.T is KONI's non-adjustable street-tuned shock, slightly firmer than OE but engineered for long daily-driver service life. The Eibach Pro-Kit springs are progressive-rate and engineered to preserve stock-shock travel, so wheel hop and harsh bottoming aren't part of the deal.

Features

  • Complete shock + spring package: everything for all four corners
  • KONI STR.T non-adjustable shocks (slightly firmer than OE)
  • Eibach Pro-Kit progressive-rate lowering springs
  • Typical drop: ~25-35 mm front and rear
  • Bolt-on fitment with factory hardware
