KW Street Comfort Coilovers – BMW 335i / 335is Convertible (E93)

OVERVIEW

KW Street Comfort is an individual sport suspension built around maximum comfort. The height-adjustable system allows a lowering of roughly 10–40 mm depending on the vehicle, giving the flexibility to improve the stance and to work with aftermarket wheels.

The moderate lowering also has a positive effect on driving dynamics and road contact. Because the drop is discreet, more spring travel is retained, and the comfort-oriented spring is paired with a harmonized damper so ride quality stays the priority.

This application is for the rear-wheel-drive BMW 335i and 335is Convertible (E93).

TECH RESOURCES

Additional Parts Required

• Four-wheel alignment after installation is mandatory — KW requires the suspension geometry to be reset to the vehicle manufacturer's specification once the final ride height is set.
• Professional installation required — KW states that suspension components must only be fitted by a trained workshop. Impact wrenches must not be used on piston-rod fasteners.
• Ride-height sensors must be disconnected and removed before strut removal on cars fitted with adaptive/xenon headlight leveling.
• Driver-assistance systems (radar and camera based) must be re-verified and recalibrated after the car is lowered.
• Check wheel and tire clearance to the strut body after installation; spacers may be required where clearance is marginal.
• Not for cars with Electronic Damper Control (EDC). EDC-equipped cars require a different KW application.
