Details

The Stance+ Street Coilover Kit for the BMW 4 Series (F33) Convertible is engineered for drivers who want their car lower, tighter, and better looking without sacrificing everyday usability. The Stance+ Street coilovers are made from tough steel construction, and powder coated black to help protect against harsh British winters. The dampers are oil-filled and uprated by 25–30% over standard.

The Stance+ Street Coilover kit is a huge upgrade over the stock suspension. It keeps your BMW 4 Series (F33) Cabriolet more composed where the factory setup feels soft and vague. With the 25% firmer spring and damper rates corner entry is more predictable, body roll is significantly reduced, and the whole car feels firmer and more predictable when driven hard. The ride is firm but forgiving. Stiff enough to feel sporty, smooth enough for everyday use. A very popular coilover kit used by plenty of BMW (F33) customers.

The BMW 4 Series (F33) already has the looks, however, you can't beat the look of a lowered BMW 4 Series Convertible. Bolt on a larger diameter set of wheels and it's one of the best looking cars BMW ever produced.

The Stance+ Street kit lowers from 30-80mm, giving you a huge range of lowering. A lower ride height fills the arches, sharpens the handling, and gives your Convertible the road presence it deserves. 

Fitting is a straightforward swap with your factory suspension. The kit Reuses your OE top mounts and bearings (though we'd always recommend fitting fresh ones). Get it fitted by a qualified mechanic, have the tracking and alignment reset on a proper Hunter laser alignment machine, and you're good to go. Backed by a 2-year unlimited mileage warranty.
