ST Suspensions Lowering Springs 40/30mm – BMW E46 3 Series 330d Diesel Saloon/Sedan 1999-2005 – Sport Drop Kit Coil Spring Set – Chassis 346L/346C/346R/346K

Transform the way your BMW E46 330d saloon drives and looks with a premium performance spring set engineered for a 40 mm front and 30 mm rear ride height drop. Expect sharper turn-in, reduced body roll and a purposeful stance that complements the 3 Series chassis while retaining everyday comfort on factory shock absorbers, including cars fitted with electronic damping.

Perfect for owners who want a handling upgrade without the expense of coilovers, these sport coils deliver a balanced rake, improved stability in fast corners and a cleaner, lower road presence. We have fitted these on customer E46 diesel saloons and feedback has been excellent for both drivability and aesthetics.
