KW V2 Coilover Kit – BMW 135i Convertible (E88)

OVERVIEW

The KW Variant 2 coilover system is aimed at the experienced driver who wants to set both the ride height and the damping character of the car. On top of the continuously adjustable ride height, the Variant 2 adds infinitely adjustable rebound damping, which is what governs the pitch and roll behavior of the car — wind it up for a tighter, flatter platform, back it off for a more compliant ride.

As with every KW coilover, inox-line stainless steel technology is included at no extra charge and the adjustment parameters are German TÜV tested. Comprehensive KW documentation is supplied so the kit can be set up correctly.

TECH RESOURCES

Additional Parts Required

• Four-wheel alignment — a full four-wheel alignment is mandatory after installation and after any subsequent ride-height change.
• Professional installation — KW specifies fitment by a qualified suspension shop; installation at a KW specialist dealer is also what qualifies the kit for KW's extended warranty coverage.
• Tire-to-strut and fender clearance check — verify clearance at full lock and full compression, particularly with aftermarket wheel and tire packages.
• Ride-height sensor handling — cars fitted with headlight-leveling or adaptive-damper ride-height sensors require the sensor links to be relocated or adapted to the new ride height per KW's instructions.
• Installer-supplied tools: spring compressor, torque wrench, and the standard BMW suspension service tools.

Installation

• KW supplies vehicle-specific printed installation instructions and a parts certificate (Teilegutachten) in the box with every kit.
• Speed Logic could not confirm a downloadable KW installation PDF for order number 15220062; contact us if you need a copy before purchase.
