Transform the stance and handling of your BMW 3 Series F3x
Give your BMW a purposeful ride height drop and sharper road manners with this ST sport spring set.

Why enthusiasts choose this spring upgrade
- 30 mm uniform drop front and rear for a level, OEM plus appearance
- Noticeably tighter turn in, reduced body roll and more planted high speed stability
- Engineered to pair with standard shocks, including vehicles with electronic damping systems
- Crafted from chrome silicon spring steel, multi tempered for long term performance
- Durable epoxy coated finish for corrosion resistance through British weather
- Vehicle specific rates for the F3x platform to keep ride quality intact
