Sport spring set for BMW 3 Series F3x — balanced 30 mm drop front and rear

Transform the stance and road manners of your BMW with this ST performance spring package delivering an even 30 mm ride-height reduction at both ends. Engineered for the F30 Saloon, F31 Touring and F34 Gran Turismo from 05/2013, it’s a straightforward upgrade that sharpens handling, cuts arch gap and keeps everyday comfort intact.

Ideal for owners seeking a subtle, OEM-plus suspension upgrade without going to coilovers, these precision-wound springs work seamlessly with factory dampers, including cars equipped with electronic/adaptive damping. We’ve fitted these on customer cars and in our own builds — feedback on turn-in, stability and looks has been outstanding.
