BMW M3/M4 Lowering Springs by CTS Turbo

CTS Turbo's lowering springs for the BMW F80/F82 M3/M4 are made from high-quality SAE 9254 / DIN 54SiCr6 spring steel wire, so they're safe, strong, and won't fatigue over time.

They're tuned for the street — focused on handling, braking, and responsiveness without the harsh ride other brands deliver. Engineered in-house and thoroughly tested, they showed no detriment or deterioration to the OEM strut over long-term use, so you can count on them holding their performance for years. Lowering also gives the car a more aggressive stance and that flush look, without compromising daily drivability.
