Product details
OVERVIEW
KW Variant 2 is the sporty, personalized coilover kit. It is built for the driver who wants to set the ride height of the car individually and also wants control over the damper setting, so the suspension can be fine-tuned to their own requirements.
The adjustable rebound damping governs the pitch and roll behavior of the car, letting the balance be adapted to personal driving preference. Compression damping is set at the factory by KW's engineers, so the kit keeps a predictable, road-friendly character while the ride height and rebound are dialed in.
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.
