KONI Yellow Sport rear shock for the E89 Z4 is designed for sport/lowered springs and features digressive valving combined with two-position adjustable rebound. Digressive valving is stiffer than OEM shocks on slow suspension motions (cornering) but gets softer as shock piston speeds increase (bumpy pavement). This shock is tuned for sporty handling but engineered to maintain a level of ride comfort acceptable to most. The adjustable Sport shock has more control and is tuned for higher performance than the self-adjusting FSD shock.
The shock rebound (extension) is adjustable - use the base setting at first and as the shock ages you can switch to the stiffer setting. Or jump right to the stiffer setting for ultimate control. Rebound adjustment is made by removing the shock, compressing it, and turning the shock body to engage the new setting. Shock travel has been optimized for lowered springs such as Eibach or H&R but can also be used with stock springs if more ride control is your only goal.KONI Sports Feature:
- Adjustable rebound settings (compress and turn adjustment)
- Significant handling improvement
- Reasonable ride quality
- Re-buildable for custom vehicle setups
- Best KONl shock for all lowering springs
- Lifetime Warranty
This KONI Z4 shock uses all of the factory mounts, bump stops, and dust covers. We suggest new mounts and bump stops if yours have more than 50,000 miles.
With a lifetime warranty these are the likely the last shocks you will ever need to purchase.Click here for KONI shock adjustment procedures.
