Transform the way your BMW F33 cabriolet drives and sits with this AC Schnitzer sport spring kit. Expect a confident, planted feel on British B-roads and motorways, a tasteful ride height drop for a cleaner stance, and sharper steering response while keeping day-to-day comfort intact. This is a precision chassis upgrade designed specifically for the 4 Series Convertible 435i and 440i.

Ride height reduction
