MMX Performance BMW F8X M2 M3 M4 Height Adjustable Sport Springs
1 IN STOCK
The MMX Performance BMW F8X M2 / M3 / M4 Height Adjustable Sport Spring Kit is the most versatile suspension upgrade available for the F-Series M-Cars short of full coilovers. Unlike conventional fixed-drop lowering springs, the MMX HAS kit gives you a fully customizable ride height, front and rear, infinitely adjustable through the entire travel of the threaded perch, so you can dial in your stance exactly where you want it without ever sacrificing the factory adaptive M damper.
The kit retains your factory adaptive M dampers, making it a far more cost-effective path than a full coilover conversion while preserving the high-quality, sophisticated electronic damping the F8X chassis was engineered around. Four threaded adjustable perches install underneath the progressive-rate sport springs. The method of adjustment is exactly the same as on coilover suspension, a simple turn up or down on the threaded platform changes ride height, letting you fine-tune front and rear independently until the car sits exactly the way you want.
The total adjustment range is generous: 20–45mm of front lowering and 10–35mm of rear lowering versus the factory ride height. That's enough range to dial in anything from a subtle, OEM-plus stance for a daily-driven car all the way down to an aggressive, level, track-day rake, without ever needing to swap springs or guess which fixed-drop kit is right for your build.
The springs themselves are progressive-rate units, finished in MMX's signature metallic grey. The progressive rate was specifically chosen to match the damping characteristics of the factory F8X M2 / M3 / M4 suspension, delivering improved dynamics under hard driving without sacrificing ride quality during normal use. Push on through the corners and the F8X chassis really comes to life, lighter, more direct, and with significantly sharper turn-in.
